Beretta PX4 Storm - Underrated is an Understatement!

[arcfide]

I've read some people have some grime and dirt congeal inside of the action/firing pin channel of the gun, even under relatively low round counts which lead to light strikes. After taking down the slide and thoroughly cleaning the slide and all parts, and keeping excess lube from getting in there, they apparently had no further issues.

[DRJ]

So, I've been waiting for this spring to arrive. Saturday it was at the USPS distribution center in Lafayette, LA, which is normal. Then checking the tracking number showed it as being "In transit - delayed". I checked this morning and got this:




I had to google "GU" - it's Guam. Guess that USPS thought it needed a Pacific island vacation. :rolleyes:

I have a couple due to arrive tomorrow. I sure hope mine don’t end up in Guam. ��

I ordered a replacement and it's supposed to be here today, though I doubt it'll make it since it's in Baton Rouge. The other one is on its way back from Guam. I wouldn't be surprised to have them both show up the same day.

The replacement I ordered got here yesterday. I installed it and took it to the range today and put about 100 rounds total of S&B, MEN and Federal AE hardball through it and it ran fine. When I got home from the range, the one that went to Guam was in the mailbox. I love it when a plan comes together. :)

[revchuck38]

Using various 124-grain loads, the gun seems to print an inch or two low at seven yards using the top of the front sight as the POA. It could well have to do with the way I hold my mouth or something else unrelated to the pistol. Has anyone else experienced this?

I'm planning on sending the slide to Ernest for the Ameriglo sights he offers. Do these change the POI relative to the stock sights?

Worst case, I could switch to 147s for this gun, but keeping two 9x19 loads would be a hassle.

Our experience with the Storm 9 has been that on a 1.5" square @10 yards the front sight needs to be aligned with the top of the sight even with the top of the square to hit the center with 115 grn loads. We would have to hold the top of the front sight even with the bottom of the square to hit the center with 124 grn loads.

[DRJ]

I got my springs and immediately put them in my two PX4s. My new compact turned out great but I already had a 12# in my sub compact and could feel little deference in it. The compact 9 has a much better trigger with a much shorter reset than the sub 40 and I’m not sure I understand why.

At 20,000 rounds on your test PX4 you replaced certain parts and springs. 30,000 rounds later, at 50,000, did you replace any parts and springs?

I did replace parts along the way. Recoil springs ever 10k until I hit 30K. I did the parts listed at 20K. The Cam Block at 44Kish (whenever it broke). That's it, nothing was replaced after 30K other than the cam block. Gun has not been fired since the end of the test. So as of now, it sits at 50,000 rounds in my safe.

I have thought about it, I think it would do it with no problem.

[revchuck38]

I've been shooting my full-size PX4 for a while now. I've installed the large grip insert, but still find that my strong-hand thumb occasionally leans on the slide release hard enough to keep the slide from locking back on an empty magazine. This hasn't been an issue with my CZ-75B because my thumb rests on the frame-mounted safety and can't hit the slide release.

Would installation of the stealth slide release help with this?

Used PX4 mags on sale

[MGW]

OK, so I don't want to over-promise and under deliver. There are a lot of things in the works right now. I will list some and do my best to make the list in order of when I think they will be available;

1. Full-Size PX4 MOD 4 guns available from ROBAR at the same price and configuration as the Compact Carry.
2. PX 4 Compact Carry MOD 5. More stuff that I do to my gun. Spurless Hammer, 17 round Mags, Mag bevel, maybe a cool barrel crown?
3. Beretta 92G Elite LTT. Details on another thread.
4. Full-Size PX4 Carry Comp (or something like that) from Beretta.
5. New safety de-cocker design that is easier to use but still low profile. Some people really struggle with using that Stealth Lever and that needs to be addressed.
(I have made a few prototypes, but to make it right Beretta Italy is going to have to make it)

Ameriglo is working on both T-Cap sights (just like the PX4 CC) and Fiber Optic sights for the full-size.

Keep your fingers crossed and keep talking here on the forum. I am trying to listen and get the right info and decisions made at the right places to build the things that you guys want.

Any hints on when we might see the LTT Elite?

Just had the first decent day of weather and days off to get a solid range session in. Ran a whole bunch of various drills the PX4CC Full Size. Various tests,, modified Vickers 300, stuff at speed and stuff slow. I am really impressed with the handling of the gun, the trigger and the sights. Love my PX4CC,s for daily concealed carry, but the full size will be a dedicated OWB training gun. Tried the 92’s in that role, but I seem to just meld much better with the PX4CC platform.

Finally handled one of these today at the LGS. Had never seen one in the flesh, much less touched one. Trigger wasn't bad, controls seemed well placed. Grip was definitely slick, though. Think I'd prefer stippling to Talon Grips. Been thinking about this as an option for the retirement carry gun (the CC version), along with the CZ P07. Gonna have to get ahold of a C model to shoot.

Also realized why I don't go to gun stores anymore. Nice older man behind the counter nearly had a stroke when I dry fired the pistol in DA and SA. Informed me I may have broken the gun by doing so. *Sigh*. Oh well. His store. I just apologized and left. Nice gun, though.

[revchuck38]

I really like my PX4, but it shoots low for me, about 1-1/2" at 12 yards. What I'd like to do is send it to LT and have the Ameriglo sights installed, but I don't want to go through the expense and end up having to use Kentucky elevation (it's on for windage).

I've got a class next Saturday that I'd like to use for final vetting to make this my new carry gun. I'm going to go old-school next week and take it to the range with ammo and a flat file and get the POI where I want it. I've already noted that I've blacked out the rear dots and painted the front sight bright red for the redneck version of the Ameriglo sight picture. I'd really like it to end up a bit more...elegant.

One option is to go with the Ameriglo front sight and the adjustable rear sight that Beretta offers. Two possible issues are incompatible notch width and the robustness (or lack thereof) of the adjustable rear sight.

I haven't been able to find out if Ameriglo offers different heights for their rear sights; their website shows one rear for everything.

If anyone has any input on this, I'd appreciate it!

The PX4CC for me has become a stellar retirement gun. It simply carries small like everyone else’s sub compact but shoots like a full size. The only drawback for me is that magazines are not something you can find anywhere. Other than that....a great choice combined with a lightweight J frame.

[revchuck38]

Done. I had to take the front sight down to the top of the dot to do it, but it shoots to POA now.

[rsa-otc]

I have been concentrating on the M&P platform for the last 5 years as my competition & duty weapon. I recently picked up a stock PX4C as a project gun, to fiddle with. With only 10 rounds through the gun and just changing the hammer spring to a 14 lb hammer spring, installing Talon Grip Panels; I shot an IDPA match with it. So call me an idiot or gutsy (probably a gutsy idiot) I placed 7th overall out of 40 shooters, not bad for not having spent any time with a DA/SA gun since the 80's. With only a 110 rounds down the pipe I equaled my best score 299/300 on our company's Q course that uses a 6 inch bull out to 15 yards (No one has shot a perfect score on this course). When I do my part the bullets land where I aim.

I have since converted it to a G variant and installed a 12 lb hammer spring. The instillation of the 12 LB spring made a bigger difference in the quality of the trigger than the 14 lb did. Future plans are to shave and refinish the right side lever of the slide release, install Langdon Ameriglow sights and install Earnest's new safety/decock levers when they become available. I also see a Full Size gun in my future.

[willie]

Revchuck, you may find a higher rear sight by checking with Beretta customer service.

[revchuck38]

willie - Thanks, you're probably right. I kinda like the way it is right now, redneck though it may be.

I can't stand gun stores anymore to the point where I'm more than willing to take the chance on a gun sight unseen most of the time. A few different online retailers have good return policies and I'd rather not deal with the bubbas and the down-talk from the shop owners.

Done. I went through Karl Rehn's Defensive Pistol Skills 3 (https://www.krtraining.com/KRTraining/Classes/defensivepistolskillsthree.html) course. The gun ran flawlessly using my 124-grain FMJ handloads. The DA trigger has smoothed up to the point where it's almost revolver-like and my only mod has been to install a 12 lb. hammer spring. The only issues I had were due to excessive operator headspace. :rolleyes: I used a JMCK OWB2 and it also performed excellently. I have a new carry gun. Now I just need to sell some stuff to finance a backup.

Great report. I am only running a 12lb Hammer Spring as well, plenty happy with the trigger pull.

Yeah, I really want to try the dot on a PX4. I just got to shoot one of these yesterday http://www.shieldpsd.com/portfolio-posts/reflex-mini-sight

Pretty impressed with how low profile it was. You would not need suppressor sights with this setup, very low profile.

Is the PX4 designed in such a way that one could mill the slide for an RDS? All the pics I’m seeing have the RDS mounted really high on an adapter, which seems less than ideal.

I am not sure as the PX4 uses the same firing pin safety design concept as the 92-series. At the very least, the sight and/or base would have to be able to accommodate the firing pin safety's vertical movement. My concern with such an arrangement is that dirt/debris could be trapped with such a setup, leading to no firing pin safety function or no ability to fire the pistol (depending on which position the safety gets "trapped").

This is the only thing holding me back from getting a px4 to be honest. Currently, I still shoot more accurately and faster with irons, but I am confident that I will be able to overcome that soon and open up some new possibilities.

Agreed. After fondling the 92 and PX4 at the LGS, I’d be very tempted to join the Beretta cult if there was a way to mill for a RDS.

A LTT 92/PX4 “MOS” would be too much to resist.

[LockedBreech]

I wonder if there would be a way to have a sight base that allowed the vertical movement of the firing pin safety but also kept it housed/shrouded, like the hammer on a Smith 642, to avoid debris issues.

It's a fuzzy development goal, yes.


It could be done fairly simply in the same manner we did it on the APX actually, but it's a matter of finding time/resources to do it.

The pics I’ve seen have the adapter mounted in the rear sight dovetail so it sits higher than a milled slide. I don’t know how much it matters for practical shooting, but I ASSume that height increase is less desirable.

I have one being built right now, hopefully, it comes out right.

I got to play with a students gun, PX4 Compact Carry MOD 4, that had a low mount RDS on it. It looked really nice, but I did not get to shoot it and forgot to take a picture. It looked really good.

I think low mount on the 92 with current optics is a not starter. Mainly because of the shape of the slide and the fact that the firing pin channel is so high and close to the top of the slide.

[David S.]

That’s kinda what I thought.

Yes, we can do that as well. The process is exactly the same between the full-size and compact.

[revchuck38]

I had LangdonTactical add the Ameriglo sights to my PX4, and while they're dead-nuts-on for elevation, I'm hitting about an inch left at ten yards. Both sights are perfectly centered in the slide. I tried drifting the rear to the right using a 1/4 lb. brass hammer and a brass punch and only ended up with a brass-colored smear on the sight. When this happened with my CZ-75, I reverted to a 1 lb. claw hammer and a steel punch. Any reason to NOT do this with the PX4?

So, there is more to moving the sight than what you use. How are you holding the slide is very important as when the slide is in the vice. The Beretta sight tool is OK for moving sights in this case because the sights have already been replaced and will alow you to make a small adjustment without banging on the sights with a bunch.

Factory sights have been painted in place as they are installed before the slide gets final finishing. They are very difficult to move unless they are factory night sights of some type, like the Compact Carry.

For removing or moving standard factory sights, I suggest using a large vice, with smooth sided jaws, and a leather cowhide padding to protect the slide (Brownell's), and a stout brass bunch with a BFH. Rubber jaws are going to allow the slide to move too much and you will likely never move the sights. This method could also be used for small adjustments with other sights, but it is not a very precise technique.

[PX4 Storm Tracker]

Additionally, I have found that heating the Bruniton with a blow drier a little first loosens it slightly. A trick I learned from Beretta years ago.

So if you can actually give me a comparison/description from experience, I would appreciate it.

So it looks like I'll be the owner of a PX4 Subcompact here in a few days. If I understand correctly, safety/decocker levers and hammers are interchangeable with the other two models but the chassis or whatever it's called that houses the trigger group is different so competition trigger groups or Langdon TJIBs won't work. I'm guessing the hammer springs are different lengths too. But I'm having trouble wading through all the pages of all the threads to find out what parts are interchangeable between the subcompact and the fullsize/compact. The plan is stealth slide release and decocker levers and a spurless hammer to reduce the external dimensions as much as possible and whatever I can do to improve the trigger. The gun I'm getting is pretty well used so it's just going to be a test bed to see if I like the subcompact and if I can make it work for me along side it's larger brethren.

A lot of your observations are correct. The SubCompact will use the same decocker levers and slide catch, though it normally comes stock with a low profile slide catch, anyway. The hammers are the same in the different Storms, but the struts are different in a SubCompact. It will take the same hammer spring, though.

You are correct that the hammer assembly unit is different in a Sub. It seems to go by different names... confusing. It is a hammer assembly unit in Beretta speak. Some call the competition version a competition trigger group because it will help single action trigger pull. But, it does not contain a trigger or trigger bar. In Gunsmith terms it is a fire control group. A rose by any other name...


You could find a part of interest here: https://www.brownells.com/schematics/beretta-/px4-sc-sid878.aspx And see if it is the same part number as here: https://www.brownells.com/schematics/beretta-/px4-compact-sid928.aspx Or here: https://www.brownells.com/schematics/beretta-/px4-sid879.aspx to see about any other parts that come to mind.

I have a PX4 Type C Constant Action as well as both flavors of S&W 3rd Generation DAO and HK LEM. To me, the trigger is very much like the original S&W 3rd Generation DAO or a well-tuned S&W DA revolver. The trigger pull has about 8# of weight but does not stack. There is no stacking to the break, and the break itself is not telegraphed. The trigger resets a bit before full return travel with very little tactile feel other than there is no weight pushing the trigger back.

The hammers are the same in the different Storms, but the struts are different in a SubCompact. It will take the same hammer spring, though.

You are correct that the hammer assembly unit is different in a Sub. It seems to go by different names... confusing. It is a hammer assembly unit in Beretta speak. Some call the competition version a competition trigger group because it will help single action trigger pull. But, it does not contain a trigger or trigger bar. In Gunsmith terms it is a fire control group. A rose by any other name...


You could find a part of interest here: https://www.brownells.com/schematics/beretta-/px4-sc-sid878.aspx And see if it is the same part number as here: https://www.brownells.com/schematics/beretta-/px4-compact-sid928.aspx Or here: https://www.brownells.com/schematics/beretta-/px4-sid879.aspx to see about any other parts that come to mind. Brownells is Beretta’s official distributor of OEM parts.
On the schematic a little number will be next to a part, click on it and it will show up below the schematic. Remember that parts found on the PX4 full size page might be for Type C or D and not compatible with Type F or G.

Awesome man. Thank you. If the 12# hammer spring works as well in the subcompact as it does in my compact that'll do just fine.

That spring has a good reputation. If your SubCompact is well used, you might consider replacing the slide rebound spring, if the prior owner has not.

Yeah, first thing I do is put in a new a recoil spring and shoot it. If I like it I'll try and find one in a known condition if not brand new for carry.

I have a PX4 Type C Constant Action as well as both flavors of S&W 3rd Generation DAO and HK LEM. To me, the trigger is very much like the original S&W 3rd Generation DAO or a well-tuned S&W DA revolver. The trigger pull has about 8# of weight but does not stack. There is no stacking to the break, and the break itself is not telegraphed. The trigger resets a bit before full return travel with very little tactile feel other than there is no weight pushing the trigger back.

farscott - Have you tried the Type D version as well? I've got one and the DAO is pretty nice, but I'd be interested in a comparison between the two.

Glad to know. Hard to go wrong with a full-size Beretta pistol for less than $300 out the door, including FFL fees.

Once it arrives, I will have full-size PX4 samples in Types C, D, and G. I will probably add a Type F to complete the series.

Anyone have experience on the FDE Compact version? Seems hard to find, I know the slide is cerakote but was wondering if the frame was cerakote or actual dyed FDE?

I have the FDE compact. The actual polymer is FDE, not coated. So you can sand it, stipple, whatever and it'll still be fde.

Picked the gun up today. In typical PX4 fasion the trigger isn't bad as-is. I'll test fire it this weekend to make sure it works then I'll steal the 12# WC hammer spring from my compact to put in the subcompact and the compact will get a TJIB.

I tried a PX4 at the gun store a few years ago (when they were hated). The trigger seemed smooth and better than most.

For a standard model mass production DA/SA pistol, it's the best out-of-the-box trigger I've ever felt.

Yeah, on a factory gun they are impressive. After a little use,, they are even better. We had some old show guns side by side with the Compact Carries when the first came out. Old show guns had had the triggers pulled a few hundred thousand times likely, and were pretty impressive. It was hard to tell people that the Compact Carry had a better trigger on them because the DA was better on the old trade show guns.

This stuff is why I really like the combination of NP3 with the rotating barrel. Everything is a give and take. The design of the gun gives great recoil characteristics and easy of slide manipulation. The negative is it can rotate stuff inside. On my Guns, which are now all NP3’d, I have not seen some of the issues others noted, except in one case with a bad round. In that case, that hard PX4 lock up the NP3 allowed me to at least clear that bad round. It was some work, but at least did not require any tools of hard object assistance.

[Guerrero]

https://m.youtube.com/watch?v=4Y5akPAgYkA

Watched that, too. Remember, "for entertainment purposes, only." Not sure how seriously MAC takes his own test, as he doesn't carry an Arex Rex Zero 1 (the only gun to do really well in the "Gauntlet" test), and he's never tested (that I know of) his own carry gun, the CZ P01 Compact.

So, make of this what you will.

[Swamp Buddy]

I am not going to sell all my PX4's due to his test

[Trukinjp13]

I agree. But usually his tests have shown valid problems with certain guns. I take what data I can pluck from them. They are entertaining to me and he seems to have a pretty good control at least.

He also states that certain parts of the test would give him no pause in a carry gun. But failing the basics makes him nervous. And also second Dagga on the np3 treatment, seems like that would help slick things up quite a bit without lube.


Didn’t Msparks do his own little test and the px4 choked but the p30 chugged along? Or am I mistaken? Also, I absolutely loved my px4cc and this would not make me sell mine.

That test is so far from a real test it is not even funny. He is clear that it is for "entertainment purposes only" but he still likes to draw conclusions from the test. It is not even close to the way the military runs an environmental test. I have watched several of the videos and there is not a lot of consistency between test when it comes to the sand, dirt, mud etc. In the case of a true test, even the moisture level of the sand has to be the same. Not to mention the size of the sand, how it is placed on top of the gun, the amount of sand that is placed on top of the gun, the direction it comes from, the velocity of the sand when it hits the gun, etc. The same controls would need to be in place for all the other parts of the test.

Even if he was controlling all of those factors, it is still only a sample of one. In order to get any kind of real statistical data, every pistol would have to be run multiple times through the exact same test with all the proper controls in place.

I also find it funny that he clearly has a bias against the rotating barrel as he thinks that is a problem. I mean what other military grade guns would have a rotating barrel/bolt. Like, say an AK47/74, M4/M16, M1 Garand, M14...... I don't think I need to continue.

[LockedBreech]

The traction those gauntlet tests have gotten makes me want to buy more PX4s out of spite. My PX4 is headed on to 11 years and at this point close to 16K rounds with 2 recalled stoppages. My tactic is avoiding placing containers of gunk on my nightstand or in my glovebox.

Someone also pointed out he hasn’t done the gauntlet on his own carry gun and doesn’t carry the Arex himself. That’s confusing. If he really thinks his tests are sound why not abide by their results?

Though buying a beat to hell PX4 for pennies and having it Robar np3+ treated is an idea I now wanna try thanks to Dagga Boy.

[PX4 Storm Tracker]

When designing a pistol, decisions have to be made on what it will be used for most.

In WWII the 1911s had to endure long terms of not being cleaned correctly, being dropped in dirt or sand, and not being taken care of. These pistols had very loose tolerances in order to be able to function reasonably with these abuses. The accuracy of these pistols was very poor because of the loose tolerances. Colt later made a Gold Cup pistol with tight tolerances for very good accuracy, but it required more cleaning and maintenance.

If the PX4 was designed to be soaked in water and then put in sand, pressed into every place, then that would have been the way it would be designed. But then, the sloppy tolerances would give 5 inch groups at 10 yards.
Reasonable compromise between the more popular need for good accuracy and longevity of the pistol outweigh the rare need that if someone drops it in water and then drops it deep into sand and steps on it that they won't be able to stop, shake it out, rack the slide a time or so and then shoot.

If a person perceives that this risk is there for them, I would suggest installing the optional lanyard loop and a lanyard.

Well, like Mac says these "tests" are for enterainment only, and, he would not recommend buying or selling a pistol based on the tests.. To me, that pretty much says it all.. It's enterainment only, not to be taken too seriously. As far as Mac testing his P-01,(I think that's what he's carrying, if I'm wrong, someone please correct me) that would be fun to watch. I don't know if he has ever tested a 75 series CZ or not. I've got a SP01 tactical (decocker), and one of the steel framed "SP01" compacts. Both are excellant pistols. IMO, these pistols have lots of nooks and crannys, plus numerous small springs,detents, which I'm sure when loaded up with a small amount of sand, dirt, mud, would stop working, I'd guess a decocker version may even be worse as it's sear cage is a bit more complicated. So, I don't put alot into these "tests" except they're fun to watch.. My two pennies of advice is.. don't get butthurt if "your" pistol dosen't make it..after all, it's the internet..

There is always the choice of the PX4 Subcompact. Smaller and more beachwear friendly.:p

True. Mac is honest enough to state that that tests are for entertainment only, and that decisions on buying or selling should'nt be made based on these tests.. Still, you're right, people will take these test as gospel.. look at the firestorm that was caused when Mac "tested" the VP9, Granted, for a striker fired pistol, the VP9 is, IMO a bit overly complex, and failed after being dunked in a stream and stepped on. The butthurt fallout from that was epic, some hardcore HK fanboi's wanted Mac's head on a pike, others sold their VP9's in disgust.. others still, snapped up backplates for the slide that did'nt have the hole in it for the back of the striker, in a vain effort to keep mud, dirt etc, from getting in, just as soon as they came to market.. They did'nt even think twice, this was an issue that had to be fixed, and fixed NOW.Some aftermarket parts vendors make a small fortune.. All of that because of one, half-assed "test". Now that, was entertaining....

[Doc_Glock]

Watched video. The PX4 did not do any worse than other of several popular, quality guns I have seen go through this particular test. I don’t think anyone needs to get defensive about it.

I found my PX4 more ammo and lubrication sensitive than I liked. This did not improve after a trip back to Beretta. I didn’t find it’s benefits compelling enough to keep it around despite its amazing out of the box trigger.

[Bigghoss]

Usually even Tim doesn't take his gauntlet tests too seriously but this time around I felt like he was drawing way too many conclusions from this.

[MattyD380]

Scientific? No. But he presents a body of informal data points that one can draw their own conclusions from. Here are mine:

The PX4 system is less tolerant of massive amounts of crud in the action than, say... a USP45... or an Arex.

Based on what I've seen, I'd conclude that's pretty much a fact. And it doesn't really surprise me. But... short of burying the gun in gunk... I think a PX4 is just as reliable as conventional designs--with added benefits. As Storm Tracker mentioned... you have to decide what's important to you. If I was slogging through swamps, sneaking up on bad guys... I'd carry a USP45. But I'm not. And honestly, the gun did fine once the sand cleared out... and it continued to function fine with zero lube. Under "normal" circumstances, I think you could drop it in the dirt without having to worry about it.

I will say that my PX4cc has been one of the most reliable guns I've owned. Over 2200 rounds now, and zero issue of any kind. I've missed cleaning between range sessions a few times (no problems), but, generally speaking I keep the gun clean and lubricated. I don't expect any issues. Don't have any.

[BobLoblaw]

[PX4 Storm Tracker]

When designing a pistol, decisions have to be made on what it will be used for most.

There is another interesting factor that I never hear mentioned or hear misapplied. Quite a few years ago, when I was researching about the PX4 Storms, I used to pick the brain of the, then Customer Service Rep Supervisor ( e_stern ). He told me that the PX4s in .40 & 9mm were made for Police use primarily. The PX4 Storm .45 was made for military use and had better tolerances for such harsh conditions.

Normally, non-Storm folks lump all PX4s into "full size 9mm" and its Compact version. But the .45 is built differently. You hardly see anyone using the .45, much less testing it.

The point being that the PX4 full size 9 was not made for military use, primarily. Not as many LEOs encounter water levels and then sand, etc.

Interesting. Makes sense, given the SD .45's military intentions. I guess that's a distinction we often think about--certainly there are different design considerations. I would guess some guns are "consumer grade," as well.

[karam.19]

His “entertainment” disclosure is BS because he calls other guns the “competitors” and cites fairness to other manufacturers. Then, he draws reliability conclusions. I think the test is stupid and not entertaining. I take very good care of my guns and I don’t foresee myself being submerged in water or having to crawl through mud and dirt. I don’t even consider it a possibility unless I’m abducted and taken to another location. I evaluate a gun based upon how it operates in the conditions in which I live. The PX4 is a great gun specifically because of the rotating barrel. When you take care of it, it will take care of you. Lastly, which is a better “gauntlet” test, MAC’s 2 minute Poncho Test or the 50,000 rounds fired by Ernest Langdon on a PX4 he STILL CARRIES?

I have had my gun submerged in nasty lake water. No choice on going in. I sure as hell hope
It could survive being dirty or wet. Hell Glock has released specific parts to help with that.

The hammer fired guns seem to be the most reliable in these tests. Also the px4 ran great after a tap water bath with no lube. Some pistols were done once they lost all lubrication. The p07/arex/USP/92 have done the best. Which are based on or are battle proven pistols. Cz 75 series have been there and done that. The usp is proven HK badassery and the arex is basically a Sig pre Cohen to a extent. Which last time I checked p226 used to be one of the top dogs in the world. The Beretta 92 also did awesome from what I recall. Another proven pistol.

As far as strikers I think Glock and p10c did the best. Which happens to be Glock, pretty well sorted out in combat and a Glock like clone.

So yeah entertainment purposes and what not. But still I think you can pluck some knowledge from them. If you dont like it dont watch it. Move on. Plenty of other dumbshit on youtube.

I handled a PX4 for the first time at a steel challenge match last evening. I was pleased that the gun fit my hand so well, since I can't quite get the groove of my finger on the trigger of a 92FS. The double action pull was a surprise, in that it reminded me of my HK DA/SA before I converted it to the LEM trigger, i.e., heavy and kind of off putting.

There is currently a lot of love for the PX4 but in stock / base form it is a bit of a diamond in the rough. I’m willing to bet all the PF’er guns referenced here have either factory D mainsprings (16 Lb) or the reduced weight Wilson mainsprings (14 lb or 12 Lb). These make a significant difference. A LTT Trigger Job in a bag should be even better.

I've got an F version (bought new) and a D version (bought used). The slides for both went to LTT for the Ameriglo sights plus I had the F converted to decock-only using the stock safeties, and I've installed 12 lb. hammer springs in both. I'm pretty pleased with both guns. They don't need anything else done to them.

That said, I'm considering sending the D version to LTT for a trigger job with a D spring to see how smooth it can get with a factory-weight spring. I'm pretty sure the D spring would reliably fire small rifle primers and I've got a case of Federal 205s just sitting there. Primer savings would about cover the cost of the trigger job. :)

OK, let me hit this detail up again. The "D Spring" for the PX4 is not the same weight as the 92 "D Spring". The factory weight for a 92 "D Spring" is about 16 lbs. The factory weight for a PX4/8000 D Spring is more like 12 lbs. A factory PX4 standard hammer spring is lighter than the 92 "D Spring" more than likely it is around 13lbs, I have not measured them.

FWIW, the spring that was originally in my PX4 D gave a heavier pull than the Wilson/LTT 12 lb. spring I replaced it with. I have no idea how much heavier it was (and it wasn't much), and also don't know if it was a D spring or a replacement. It was nowhere near as heavy as the one than came stock in the PX4 F that I bought new. The DA in both my PX4s feels identical with the 12 lb. springs installed.

Part number EU00043 is the D Hammer Spring for a model 8000 Cougar. Likely lands in the 12.5 lb to 13 lb range in spring weight, much lighter than the 92D hammer spring, part number UD99001, which is close to a 16 lb spring weight and only available in the Steel Trigger Kit on the Beretta web site.

As to the fact that you had light strikes with the 13# CS spring and not with the EU00043 spring, I cannot explain that other than it does not sound normal and that there are several factors that could contribute to this. And it is a sample of one situation. I do know that the EU00043 spring is normally not a reliable spring in the model 92. I tried it many times over the years and did not get good results.

Please trust me that the PX4 and Model 92 Berettas have different hammer strut geometry and use different hammer springs. You will get different results between all of them. While all of the springs are very similar in shape and can be interchanged between models, they will not achieve the same results in each model.

And it is a sample of one situation. I do know that the EU00043 spring is normally not a reliable spring in the model 92. I tried it many times over the years and did not get good results.

Please trust me that the PX4 and Model 92 Berettas have different hammer strut geometry and use different hammer springs. You will get different results between all of them. While all of the springs are very similar in shape and can be interchanged between models, they will not achieve the same results in each model.

I completely trust you! Actually when I checked my records, I replaced the 13# TGIB spring with whatever spring comes stock in the Centurion Tactical from Wilson. I assumed that was a "D" spring. I ordered the EU00043 as a back up assuming it was the same as the stock hammer spring in the M9A3, LTT M9, and Cent Tac. Turns out I must have ordered the wrong spring! Sorry to muddy this thread with 92 issues.

Now that makes sense. Yes, that would be a 92 D hammer spring, UD99001. It should run any ammo on the planet in that gun and would make for a heavier than stock DA trigger pull on a PX4.

Are you guys still seeing better performance out of the compact than full size?

What’s the consensus on the subcompact?

[PX4 Storm Tracker]

What’s the consensus on the subcompact?

We have 7,319 rounds on our SubCompact 9 with no problems. Very reliable.

With ~13,000 rounds on a full size 9 and 15,605 on our Compact 9... they are both great performers.

[Hawker800]

I guess I have to go get one.

[FDE_PX4_CC]

Kicking off the year I sold my full size so I could pick up the compact. I couldn’t make up my mind on which one I wanted so I finally settled on the compact in FDE mid may.

[FDE_PX4_CC]

I really do miss that full size PX4. Only thing I ever really changed was the metallic guide rod form beretta and the SD cam block, but I felt it shot "softer” after swapping those parts out. Maybe I just need to get used to my PX4C but I felt I was a better shot with full size even before swapping out those parts.

[revchuck38]

Looks like I'll be going to Colorado the second half of next month to ride my bike up mountains. :) Apparently, CO has a 15-round mag limit, so the dozen 17-rounders I have have to stay home. I have numerous options for carry guns - I've been wearing/shooting my Sig P6 the last few days, have M&Ps in .40 and .45, and 4" K-, L- and N-frame S&Ws I could take. But I've gotten awfully fond of my PX4s, so I was thinking about getting a couple of 15-round mags from Beretta so I could carry one while there. Does anyone have experience with them? Are they as reliable as the 17-rounders?

I haven't shot mine a lot but they worked fine.

[Screwball]

I haven't shot mine a lot but they worked fine.

I’ve put plenty of rounds through mine... work great. All they do is put indents at the lower end of the magazine so rounds can’t stack that far.

NJ is a 15 rounder state... likely changing in the next 180 or so days to 10 founders. I will probably send all my 10+ rounders out of state to my godmother’s until I move... and pick them up on my way out. I likely won’t be buying 10 rounders for my guns, so I’ll have a bunch of guns without magazines for a little bit.

That’s all well and good... but I’m not chancing a felony charge, which would result in me not being about to possess firearms for the rest of my life. Add in a career in L/E that would also be down the drain due to it.

Don’t agree with the legislation that is sitting on the Governor’s desk... but if it becomes law, I have to follow it until I leave. Property outside of NJ is exempt from NJ law.

That being said... too far off topic for me to continue.

Yep... they are identical, just the tabs at the bottom. Think of them sort of like the original 92 magazines.

I believe they do 10 rounders in a similar fashion... just longer tabs.

So I have a pair of PX4 fullsize pistols and a compact, all 9mm, that I got used that I'd like to freshen up. I know new recoil spring assemblies are a good idea and I'd like to get new extractors and extractor springs for each because one had a stuck case so I figured I'd spend a few extra bucks for the peace of mind. Are there any other parts I should replace preemptively like the cam block or trigger return spring? These might go on a trip to California next year so I want to make sure they're good to go.

Before I can give an opinion on what needs to be refreshed, I'd first ask how many rounds are on each pistol?

As to replacing the extractors and springs... I'd categorize those as "if it ain't broke, don't fix it". Extractors don't always plug & play right away. Sometimes they need fitting or adjustment. If you replace the extractor you might be best to put 500 rounds on it to test its tolerances. Once carbon or dirt build up it acts differently. Extractor springs can also affect reliability if too strong. I did not change my extractor spring until 30,000 rounds and even then it was working fine. I did it because of mileage. I still have the original extractor in place.

The cam block on a PX4 is not a "wear item" like a locking block on a model 92.
Safety wise- the firing pin block plunger spring and trigger bar spring could be changed. The trigger return spring should last almost forever.

If you know more about the age or round count I could offer more. If you don't know the ages, Beretta can give you the assembly date with the ser #.

Otherwise, as a general spring and part rotation "map" see: https://pistol-forum.com/showthread.php?29478-Beretta-PX4-Storm-45-High-round-count-long-duration-usage/page3 post #24

I don't know the round count on any of them, got them used in trades and such as I was cleaning out the safes and I haven't shot them a ton yet so they'll need about 500 rounds a piece anyway before I trust them. Based on the average shooter I would guess not a lot but I did have the one case that I had to punch out. Racking the slide repeatedly didn't work so I'm guessing the extractor and/or spring is bad on that one.

Perhaps the best refreshing for these pistols is a detailed cleaning. If you know how the disassemble the slide and clean in the firing pin channel and clean the extractor very well, that might do it. Since you're getting a TJIAB your frame will be emptied enough to clean well in it. That might just do the job. You can visually inspect the extractors when cleaning.

Yes, If you had a stuck case the slide should have been frozen to it. If the slide went back manually without the case, the extractor could be faulty. Was this a double feed that occurred during firing? A double feed that causes the slide to let go and continue back without the casing does not always indicate extractor problems. It could also be caused by a weak rim.

I often can guess round counts by the wear on the sides of the block, barrel round and lug. Perhaps you can guess by this.


The only other consideration I can think of is if the pistols were dry fired a lot and you would not know it. A new firing pin for $15 is not a bad idea, while the slide is apart.

[Mark D]

After reading this entire thread I had to jump on the bandwagon. I've ordered a full size G model and it's supposed to be delivered to my FFL today.

I've already got some mags inbound from BUSA, and I'll order a 12lb hammer spring from LTT shortly. After function testing, I'll probably send it to LTT for a trigger job.

Thanks to Ernest and all of the other PF members who contributed great information to this thread.

[Bobert1035]

Finally read through this entire thread, what a great source of info!

I just picked up a dirt cheap PX4 full size 40, and looking forward to getting to know it. I went ahead and ordered the LTT 11# hammer spring, so I'm planning to pull the stock hammer spring and throwing it into my 92F, as I understand that will be lighter than the D spring I have in there. Does that sound about right?

Hopefully Ameriglo will release their FO front sight for the PX4 soon as that is my preferred sight setup (plain black rear, FO front).

[ddown]

Came home cleaned and lubed took to range what a shooter. I think I'm going to have a lot of fun with this. Ex-Military years of 92-M9 experience but this is such a great shooter back on target instantly.

[Bobert1035]

I got to shoot my .40 yesterday, and yes its a great pistol, even in .40. Accurate when I do my part. No real issues, just have to make sure the mags are seated properly, and had one round that needed a nudge on the back of the slide, which I'm chalking up to the gun being filthy.

The #11 spring definitely will be lighter. You may want to be cautious if you plan on carrying the PX4 with that hammer spring because it’s possible to have light strikes. I went with a #12 on my carry PX4.

Understood, but this is a range gun only, as carry is practically impossible for citizens in MD.

[That Guy]

Just a heads up: The other day after a range trip I field stripped and cleaned my PX4 full size. And somewhere during that, the slide stop fell out of the gun. More importantly, the slide stop spring fell out. Two people spent a lot of time crawling on the floor to locate that little son of a bitch. (And obviously, guess what happened when I was trying to reassemble that little spring and the lever into the frame? Yup... Sproing. Fortunately that time, the stupid little spring didn't get far.)

So, you guys might want to be careful not to lose that spring during maintenance. And it wouldn't be a bad idea to have a spare.

[Prdator]

So.. If you want some advice.. and its worth what you pay for it... If your thinking of getting a PX4 compact carry. get one... don't do what I have done twice (sigh) and that is to buy all the parts !!! and over a period of time build the PX4 Compact carry. Just buy a Mod 4 from Ernest at https://www.langdontactical.com/ It will be much cheaper in the long run ask me know I know...

That said I love the PX4CC If I could only have one handgun that's the one I would have!!!!

So what happens here is normally someone is cleaning down inside the mag well area from above, with the slide off. Toothbrush or rag wrapped around something and scrubbing in and out of that area. The slide stop is removed on both the 92 and the PX4 by lifting it up and pulling it away from the slide of the gun. Accidental disassembly can happen with both guns, although it is much easier to do on the PX4 than the 92. The 92 has the issue of the trigger bar spring being disconnected by this action, which they did fix on the PX4. The slide stops work pretty much the same way on both guns, but this accidental removal happens much easier on the PX4 for some reason. It has only happened to me once, but it did suck trying to find that spring on my hotel room floor :(

[willie]

Thank you for the clear explanation.

[PX4 Storm Tracker]

I stay in the habit of keeping a finger on the magazine catch while cleaning in the magazine well. This will prevent it from rising up, and if it does, it keeps it from moving out.

I’m in the minority. I like a safety on a DA/SA because it’s what I grew up shooting.

For training purposes, if you don’t normally use a safety equipped gun, get a G. I don’t carry my F-type Berettas because I mostly carry non-safety guns and I worry about forgetting to disengage. Remember that in a serious self defense situation your hands will be clumsy, slow, and moving on memory. Equip and train accordingly.

G all the way. But the PX4 is pretty easy to convert from F to G so it's not a huge deal which one you get upfront.

A type F can easily be converted to a type G with no money spent. If you start with an F you can change your mind for free. A type G cannot be converted to a type F without buying new levers.

One cannot determine what "like new" might mean to the seller, but the wear marks on the barrel, cam and slide rails do not indicate a "like new", as in.... my wife got this for me, shot it once, did not like it.

The wear marks indicate holstering (more than a few times) and having been shot, probably less than 2,000 rounds. There are no slide catch drag marks indicating being used in tactical exercises much.

So, IMHO if you like the stippling, are willing to check out the spring tensions and like it... it can be worth the $375 + whatever costs to put it in your hands. Otherwise, there are new ones from reputable LGSs and dealers for nearly that price.

I cannot get a good view of the left hammer side to see if it has been dry fired a lot. If it has, the firing pin might not be as long lasting as one would want.

Hey I am a new member here, but been reading stuff on this forum for a while. I have been really reading up on the PX4 and considering ditching my CZ P07 for a PX4 Compact. The PX4 just seems to be better quality from the start. I say this due to the known and accepted issue with breaking trigger return springs (TRS) and firing pin retaining pins (FPRP) on the CZ.

Another positive thing with the Px4 is it seams you start with a better trigger out of the box and it does not take much to get some improvement and with factory parts. With the P07, if you go lighter on the hammer spring, then count on getting an extended firing pin. Plus adding a CGW TRS and FPRP from the start seems to be normal.

I have fired a PX4 one time about a year ago. I did not really get enough time to feel it out. I do remember that grip texture was very smooth. So, I need to get my hands on a PX4 compact and spend some time with it. This is a big choice for me since I am invested in the P07 platform right now.

This is a great thread with lots of info on here!!

Don’t try to force it. It’s difficult to see from the top, but the hammer pin is retained by the little wire spring that must be pushed downward until it disengages from a locking groove on the bottom of the hammer pin. Once this is accomplished, the pin will move easily.

ETA: The easily visible part of the wire hammer pin spring isn’t what retains the hammer pin. You have to move the part below the hammer pin, and push it further down. The hammer pin spring is kind of S-shaped.

Hope this helps. Once you figure it out, it’s easier to do than it is to describe clearly.

You have to push the wire spring (just to the right of your arrow in the photo you posted) down while pushing the pin out. I use a small flat blade screwdriver and push the spring down and then twist it (the screwdriver, not the spring) to get the pin started. Once the pin is started, you should be able to pull it out.

Also, if you are not removing the grip plate and hammer spring, it helps to gently push down on the hammer.

[Dave J]

This view may help. (Hammer pin removed, and a spare hammer pin spring next to it, with the original still on the trigger pack)

Yeah, the TRS was a weak point until CZ addressed it. If you're not sure, just get the updated factory TRS: https://czcustom.com/cz-75-trigger-return-spring-trs-new.html and while you're at it get the much nicer CGW trigger pin: https://cajungunworks.com/product/floating-trigger-pin/

The firing pin retaining pin issue is not a quality issue because it wasn't designed to take the full force of the firing pin strike during dry fire. If you want to dry fire a CZ stick a small rubber o-ring in the hammer channel to cushion the blow or stick a snap cap in the chamber.

[Duelist]

Hey I am a new member here, but been reading stuff on this forum for a while. I have been really reading up on the PX4 and considering ditching my CZ P07 for a PX4 Compact. The PX4 just seems to be better quality from the start. I say this due to the known and accepted issue with breaking trigger return springs (TRS) and firing pin retaining pins (FPRP) on the CZ.

Another positive thing with the Px4 is it seams you start with a better trigger out of the box and it does not take much to get some improvement and with factory parts. With the P07, if you go lighter on the hammer spring, then count on getting an extended firing pin. Plus adding a CGW TRS and FPRP from the start seems to be normal.

I have fired a PX4 one time about a year ago. I did not really get enough time to feel it out. I do remember that grip texture was very smooth. So, I need to get my hands on a PX4 compact and spend some time with it. This is a big choice for me since I am invested in the P07 platform right now.

This is a great thread with lots of info on here!!

If you are invested to the point of having at least two of them, with associated support gear and spare parts, I’d just keep running them unless *you* are finding them to be unreliable or something, not just internet rumors of things going wrong with them, or not suiting you for some reason that you can’t overcome for a reasonable amount of work or time or money, b/c switching is expensive and time consuming, and you may or may not be in a better place after you are done.

CZ makes good stuff. So does Beretta. One may be better than the other for you, but I’d stick with the CZ for a while since you already have an investment there.

[Alpha Sierra]

I should add that with the Cajun Gun Works trigger pin, it takes 5 min to change out a CZ trigger return spring. Replacing it annually is an easy PM.

So, I got the comp trigger group installed (thx for the help!), and, to be honest, I don't see much difference in the pull. If anything, it feels HEAVIER than factory to me. Dry firing at least.

Is this the norm? Do I need a #12 Wilson spring to make this shine?

Kinda bummed I spent 90 bucks on this thing....

The comp parts are chromed but the description doesn't say what the hammer spring weight is.

The 12 or 11 pound hammer spring will make it much lighter. You probably should have just gotten this :/

I looked at that, but 165 bucks was a little more than I wanted to spend. I'll definitely order the 12 lb Wilson trigger spring from Langdon and see if that makes it better.

I have had a couple of different PX4s that got the 12# Wilson springs, and they were all improvements in pull weight over what came from the factory. Something I did not foresee was that when using the 12# with a particularly "slick" hammer group, the DA pull was beautiful, but the SA was almost a bit "too" good. That particular example was not using a competition trigger group, but rather a standard one which I had made certain had no burrs and was as good as I could "tune" without resorting to stoning the hammer and sear.

(FWIW, the trigger bar had also been given TLC.)

A better shooter with more time to train than I have available might like an SA trigger even lighter than what I ended up with on that particular pistol, but I know my limitations.

[revchuck38]

^^^^I've got 12 lb. hammer springs from LTT in my two TDA PX4s and they're just about right for carry guns with stock actions. I wouldn't want the SA lighter, though smoother DA might be nice. ;)

MY DAO PX4 D is going to LTT when budget allows just to see how nice that DA can get.

[sheepdog]

I just bought a set of carry levers and Ameriglo sights from Langdon Tactical for my new PX4 Storm Compact Inox and went to install them. After I removed the levers and rear sight, I happened to notice this for the first time...

Somehow I don't think it is supposed to look like this (sarcasm). There are also some other milling issues that are only aesthetic (hopefully), but this first one especially does not look good at all, and I am fairly sure it was not designed to look this way. What do others think? Do your PX4 Compact slides look like that? It's like it's missing a chunk of steel.

In the last two pictures, the lines intersect on one side and not the other (I noticed this previously). I brought this to the attention of some Beretta PX4 Storm owners on Facebook. Some of them said theirs match, some of them said theirs didn't, and some, when they match, both interested perfectly while at others don't. I am sure you have probably seen the picture of the slide out there somewhere on the internet with most of the steel missing under the front sight. Is this an ongoing issue? I know every company has lemons, but I don't remember seeing so many milling issues with a particular gun. I'm curious to know what others think.

[gato naranja]

I had your Inox PX4's twin. Almost identical in its slide eccentricities: the wavy, "kitchen-foil-thin" metal under the front sight, the small "gap" at the firing pin channel and the "lines" at the rear. The thing was flawless in function, but that kind of stuff detracts from the whole "pride of ownership" thing.

Other than those "features," the slide itself was actually kind of impressive from a machining/finish standpoint. It had, without a doubt, the most crisp slide serrations I have ever come in contact with. Be that as it may, I have not been real impressed with any Inox versions of Beretta's handguns, and do not consider them worth a premium.

[Dave J]

FWIW, that "crack" by the firing pin hole is an intentional stress relief cut. It's supposed to be that way, and Beretta has been doing that for about 30 years now.

If you're looking at the offset in the milled vertical flats, that is also intentional and by design. If you study it a bit, you'll note that the asymmetry has to do with how the other working parts are arranged. Again, this is a carryover from the 92, and it's neither new nor random.

As far as the front sight dovetail, neither the 92 nor the PX4 has a track record of sight failures during use. On the contrary, they have a reputation for being solidly mounted to the point where they can be very difficult to change, and that was certainly the case on all the Beretta pistols I've done sight swaps on. So, I don't quite get the fuss about with what it looks like underneath.

Geez, color me stupid. However...

That stress relief cut was one of the only two ragged areas on the whole slide (the other was a cut related to the safety levers). I had to take swiss-pattern needle files to the considerable burrs on the two areas. Out of the box, the safety levers were difficult to operate, but after the file work, they were fine; as I mentioned before, the balance of that slide was beautifully done.*

*That paper-thin metal remaining under the front sight channel was unsightly but impressive in its own way... on my best day I probably could not have milled stainless that thin without tearing it. My Bruniton PX4 just came with a hole there.

To be honest, while I may have initially been interested to the Beretta 92FS perhaps because of its use in the military, the Beretta PX4 Storm Full size kept drawing my attention and felt just right in my hands.

When it became available online a year ago for $399 I pulled the trigger and have never looked back. Especially when I also eventually picked up two additional extended 20rd magazines from Beretta for like $23 apiece.

Yes, I missed the memo on buying a striker fire firearm but I can assure you that as a newbie after spending considerable time at the range I am competent in the DA/SA and can place my first shot fired pretty decent, not to mention the follow up ones. The main thing is that I also have no qualms whatsoever in keeping a round in the chamber with that double action first pull, and don’t even bother having the manual safety on the majority of the time. It is truly a good home defense firearm. As well as a real decent personal defense piece, if I wish to carry more rounds in the magazine than my EDC which is also a DA/SA a Springfield Armory XD-E 9mm single stack that carries 8+1 flush or 9+1 extended.

I unfortunately know countless people that for whatever the reason still refuse to carry a round in the chamber in their striker fire pistols that they carry. Go figure...

If you’re not consistently using the safety, I recommend you change out the safety/decocker to a decocker only. It’s best to have one manual of arms, and never be in the position where you pull the trigger but forget to deactivate the safety.

This has been covered in other places on the forum. The cut at the rear of the slide is supposed to be there. It has been there on 92F models with slide mounted safeties for about 40 years. All of the PX4s have the same cut. The cut out under the front sight is also supposed to be there. The compacts have a much larger cut out under the front sight than the full-size PX4s have.

The original cut out was to allow the factory to stake the sight from the bottom. The Compact has a larger hole there because it has to make room for the top of the barrel lug, which comes all the way under that sight in recoil.

It's back. I must've caught him at a slow time, it got to him last Monday and was shipped back out the same day. Really smooth DA, somewhat heavier than his usual because I told him I wanted to be able to shoot Winchester NATO-spec hardball with its hard primers so he used a 12 lb. spring rather than the 11. It's right up there with my breathed-on and broken-in K frames, and I ran 100 rounds of the Winchester through it with no problems. There's still this issue with the loose nut behind the grips, though. ;)

Since it is a D model, it should have been a simple job. Swap the trigger bar for a polished one, pull the hammer and polish the string strut and put in one of his springs (polished parts kept on hand). I bet it was done in less then 15 minutes. (type D trigger bar is the same as an F or G style, not the same as a C)

[JTQ]

Can anybody tell me what the width of the standard sights (front post and rear notch) and the Ameriglo set on the full size custom carry?

[10mmfanboy]

I recently installed a competition trigger in one of my standard compacts that has been converted to a cc. I got the trigger from optics planet as a "open box" competition trigger, I couldn't resist because I got it for $40.

My question is that is it normal when you thumb cock the hammer into single action that it doesn't reset the trigger right? Basically with pistol unloaded if I thumb cock the hammer I have to squeeze the trigger once then let go and you hear it reset. The pistol does not fire though simply by thumb cocking the hammer into single action.

Is this some sort of safety or is there a problem? I have shot the pistol about 300 rounds since I installed the trigger and no malfunctions if starting from double action like I normally do.

I also reinstalled factory normal trigger to see if that can be thumb cocked to single and fire, and it did.

Overall I have 2,800 or so rounds through it without a malfunction, other than me not fully seating a mag fully on a reload twice.

I am sad to say since I am heavily invested in glocks that I shoot the px4 compact better, I love shooting it actually. I want to practically vomit now when I shoot my glocks lol. The only knocks I have against the px4 compact is a useless light rail, and to me that is a big deal, and poor grip texture. It still looks like a hi point to me too, but the looks grow on you after awhile. Dare I say I might actually like it better than my m9a3, and that used to be my favorite pistol.

When you write Competition Trigger do you mean literally the trigger only or the Competition Trigger "group" that has the hammer unit assembly also?

[PX4 Storm Tracker]

10mmfanboy , If I understand correctly, you are saying that when you thumb cock it the hammer does stay back and the trigger is moved to the rear. However, the trigger is too far rearward that you must free it up by moving it for it to move forward a little and reset so that it can be used to fire. You also indicated that you can hear the reset when you prep the trigger.

This is not normal. This sounds like a sticking trigger bar. Either the trigger bar is slightly out of alignment or has an obstacle. When you thumb cock the hammer a little ledge on the hammer pulls the trigger back and the trigger bar down a little. As soon as the hammer rests on the sear the trigger should be reset and ready to be pulled. Since it is not and you hear the reset (which is the sound of the trigger bar popping up) it seems to be a sticking or misaligned trigger bar.

I am wondering when he is talking the trigger, if he is talking about the metal competition trigger, # C5G270, and if he has the pin fully in, so the bar isn't catching/misaligned slightly.

Sorry I forgot there is a metal competition trigger. Yes it is the full competition trigger group. If I thumb cock it into single action, the hammer will stay at full cocked position. When I pull the trigger to the rear the first time I get nothing, but when I release the trigger with letting my finger off the trigger you will hear it reset and then it will fire normally, but It will not on the first trigger pull. When I installed the original stock trigger it functions normally by thumb cocking trigger into single action and firing.

The trigger group didn't appear to be used it was considered an open box item. The only difference I see between the competition trigger group and my stock trigger group is the hammer spring retaining pin seems to stick out further than the stock trigger group. It doesn't appear to be out of shape or bent just sticks out further from the original trigger group.

Since the stock trigger works fine, I am assuming my trigger bar is fine. I don't really see anything different other than the hammer spring retaining pin, which is right by the trigger bar.

[10mmfanboy]

Does the competition trigger group supposed to come with a different trigger bar? Because this one did not.

And thank ya'll for all your help! I got the trigger group from gunbroker through optics planet for $40 so maybe it was just too good to be true lol.

The Competition Trigger Group does not come with a new trigger bar. The LTT TJIAB does, but the Competition Trigger Group does not.

Your observation might have found the actual cause. If the hammer pin protrudes too much it can cause drag against the trigger bar. If you get curious enough and feel like it, the PX4 will function the action without a hammer pin. You could even shoot it, but I would not recommend it. If you remove the hammer pin and the action functions correctly, you would know.
I would guess that it is the same hammer pin in either fire control group, so the hammer frame might be faulty in the new one.

There have been reports occasionally of Competition Trigger Groups not working just right. Perhaps a refund is possible....

Yes sir, That appears to be the exact problem, the hammer pin must not be in spec and sticks out from the trigger housing too far, causing the trigger bar to come out of the notch just enough to cause problems. For now I just put the stock trigger group in, I am going to look up the part number for it and buy a new hammer pin. It will still be a good deal for the trigger group.

This is the first time I've really tinkered around with the lower, your help has been greatly appreciated! The px4 is actually not that complicated of a design stand point as far as I can tell so far, I'm digging it! Great pistol!

Quick update: I fixed it! I couldn't sleep knowing I have a non working pistol, so I took the hammer retaining pin off of my stock trigger and put that on the competition trigger. Trigger now works flawlessly in DA and SA. I looked at the two pins side by side before switching them and it appears miss shaped on the competition hammer retaining spring. It wasn't locking under the pin that goes through the actual hammer, allowing that hammer pin to not be fully seated through the housing.

I did notice that the stock hammer pin is black and the competition is silver in color, so I am going to get the actual replacement for that competition trigger, but at least I know that was the actual cause of the problem. So pretty sweet deal for the competition trigger group.

I found a downside to the stock safety/decock levers yesterday. I was shooting a local USPSA match and failed to fully insert the mag on a reload. I got the dreaded bang-click, saw the mag wasn't fully seated, did a tap/rack and finished the stage. When I did the unload-and-show-clear, my left index finger was bloody. When I racked the slide, I used an overhand grasp and probably when retracting it and letting it go the sharp leading edge of the lever nailed me. Sheesh.

Citing dissatisfaction with Beretta's reconditioning of their 10 year-old .40 caliber PX4 pistols, Fresno PD is looking to jump to an unnamed 9mm.


"In both refurbished and non-refurbished pistols, the most notable issue is an excessive, inconsistent, or sporadic trigger pull. This has caused several officers to have difficulty meeting their quarterly range qualifications, raised officer safety concerns, and potentially exposes FPD and the city to liability."

Did Beretta ever offer the compact in the C or D version?

[gato naranja]

I found a downside to the stock safety/decock levers yesterday. I was shooting a local USPSA match and failed to fully insert the mag on a reload. I got the dreaded bang-click, saw the mag wasn't fully seated, did a tap/rack and finished the stage. When I did the unload-and-show-clear, my left index finger was bloody. When I racked the slide, I used an overhand grasp and probably when retracting it and letting it go the sharp leading edge of the lever nailed me. Sheesh.

The stock levers worked for me... as long as I was concentrating on them excessively. Then came the homebrew mods, the stealths and the fuglies, each of which was an improvement. When the carry levers arrived on the scene there was much rejoicing in the house.

The combination of a carry lever on the left and a stealth lever on the right is the least obtrusive option for me, but the l/r carry levers are low/smooth enough that I use the set as they come.

There are few that have the knowledge and experience of so many on this forum.

I mean, you have freaking Earnest Langdon posting here. This just blows my mind.

Anyway, back to my comment. Lacking the knowledge and experience that so many here have to parts and pieces a carry version of the PX4, I simply went and purchased the full size PX4 from LTT with the trigger job.

Have had it to the range the last three nights and am absolutely in love with the gun. Great in my hand and the sight picture suits my eye so well.

Fantastic trigger and I have PM’d Storm Tracker several times about the PX4 and he has been so willing to share his knowledge about the gun.

This is definitely my new EDC and couldn’t be happier to have found this forum.

[Whirlwind06]

I had just bought a PX4 right around the time that Earnest Langdon was first posting about it. So I kind of followed along at home. Added the stealth levers, changed hammer springs etc.
Going forward I would buy one of LTT's PX4 an call it done.

[Jared]

Had my full size PX4 out yesterday for the first time in quite a while. I’d been using the Compact PX4 and full sized 92s almost exclusively for a good little while (at least as my exclusive Berettas, been shooting other makes also). Anyway, what I really was looking into was if I wanted to try a Centurion 92 again or whether the full sized PX4 was good enough. Short version, yes, the PX4 is good enough. Money saved. I’ll just throw $20 worth of Talon grip tape on there and use what I got.

The longer version is I went 285 on the HiTS Super Test with it, cleaned Dot Torture on the first try with it, and generally shot the thing as well as I could have anything else on every single drill or test I shot yesterday. Plus, it fits in the JMCK holster I use to carry my PX4CC. I’d forgotten how flat the full size PX4 recoils until my buddy made a comment that my grip sure was on after he watched me shoot a string.

No, full and subcompact only.

[NWshooter]

Coming back into the thread to post about another range session and looked at a post above and noticed I misspelled Ernest Langdon’s name above in a separate post.

I’m self penalizing myself with some time away from the board to reflect on what a dunce I am.

But I still love this pistol and my groupings continue to improve.

Any updates on BUIS for the RDS converted PX4/PX4c?

Anyone know a company that would make a one off custom set of all black (no tritium) set?

I sent my slide to LTT at the end of March to get it milled for a red dot. I recently found out that KRTraining is putting on a red dot class next month. I emailed Aimee and it looks like mine will be back in a couple of weeks, in time for the class. Now I can be one of the Kool Kidz. :)

It has arrived, and been properly equipped. Hitting the range this weekend to a) get back into the swing of things, and b) to finally get some real time on a pistol with optics. https://uploads.tapatalk-cdn.com/20210624/12140aee1a6561d1a814db4017aff73e.jpg

Follow up: 200 rds at the range to zero and settle in. I have one of the old MOD4 Compact Carrys that has a few thousand rounds through it, and I've been doing a lot of rounds through an Elite with the Jarvis 2 port comp and an X300, so I'm not too surprised with how incredibly soft this thing shoots, but boy is it still nice. 115gr is smooth, and 147gr match loads are like a .22lr. I'm screwed if I change platforms now with how accustomed I've become to these.

Mounting the red dot and swagging a zero off the irons took all of 3 minutes, and at the range I needed only minor modification from there. I had a lot more trouble with longer distance shots (25 yds+) than I normally do with irons (I attribute that to me needing more time, not any platform issues), but I was snap shotting from low ready at 10 yards significantly faster, and far more accurately than I ever had before, and double taps were regularly within 1" of each other (I'd estimate 30% faster, group size for the drill about half of what it normally is). I was completely thrown trying to keep cadence on a string of fire, but that's just something I need to get used to with the dot. Overall, I think the majority of what's left of my ammo supply will be going through this thing because A) its a ton of fun, and B) I really need to pick up this red dot thing.

[Rdiezal9216]

Beretta guy myself, quick question. Has anyone recently sent in a PX4 for LTT optic cut? If so what was the wait time? I know quite a few people who have sent slides in and are waiting going on 14 weeks now? I’ve been quoted by Wright Armory who do the old style cut , 3 weeks. I’m just wondering because I want to send my slide in. I’m just trying to get a game plan as I teach classes etc. and want to get into the red dot game myself and my ox4 is my favorite pistol. Thanks.

IIRC, mine took eight weeks, which was the projected time (mine was in the first batch they did). LTT tends to have a pretty good handle on their workload, so 14 weeks is probably accurate.

My PX4 (full size) slide took from mid May until the end of August. Turned out great.

My PX4 Compact slide took from the end of May until the end of July. Also turned out great.

[314159]

A heads up if you have a PX4 C or D variant. I sent my C slide in to LTT for the cut and it was returned with a note that they can't do it. Bummer but turn around was very quick.

Did they say why?
I believe I asked about that quite a while back, but that may have been even in the old optics cut timeframe. I am thinking from memory, it has a different firing pin.

[314159]

It's been long enough, I can not find the email on my computer or in my memory.

There was no warning on the LTT website, at that time, about non-compatible variants. On the plus side they did get the slide back pretty quick.

I think they just don’t work on the C/D slides. I asked about having my D slide rebuilt (something they do with the standard ones) and they said they don’t carry the parts. Those parts may no longer be available.

[JAH 3rd]

Writing this after about 2 hours with my new PX4 Storm 9mm compact. This model has the decocker/safety feature. DA/SA action. Two 15-round magazines. Standard 3-dot sights. At this point a few observations. Yeah, oiled well from the factory. Going to disassemble and wipe off excess oil. Glock easy to remove the slide from the frame. The gap between the slide/frame is consistent from to back to front. Workmanship appears to be excellent inside and out. I don't have a trigger pull gauge. I actually prefer the double action pull to the single action pull. The DA is smooth and consistent but a bit on the heavy side. My first SA trigger pull produced this thought: When is the hammer going to drop? After the trigger uptake, you get to the SA wall........apply pressure and wait for the hammer to fall. It is creep free, but man, when is that hammer going to fall?? I'll get use to it and perhaps it will lighten up over time. I am very satisfied so far. Hopefully some range time tomorrow or Wednesday.

I flirted with the idea of the compact carry version of this model. It has "carry helpful" Beretta parts added to the pistol from the jump. The carry model is about $250.00 more with those added goodies. These parts are available from Beretta if I want to add them later.

Hopefully you'll enjoy your new acquisition.

An easy way to lighten the DA pull (without sacrificing reliability) is to drop in a 12lb or 11lb hammer spring from LTT.

Agreed. I have the Full-Sized Carry with competition trigger group. I ordered the 12# from LTT, then the 10#. I also ordered the LTT competition trigger bar. I stoned / polished the sear and the hammer. Loving the smooth action. I did order a digital trigger pull meter.. but it was faulty. Just received replacement; however, I have since sent most of the PX4 to CCR for refinishing - their CPII finish. Don't expect to see it for another 7-8 weeks.

[JAH 3rd]

Took my Beretta PX4 compact to the range for the first time today. About a week ago I took the pistol apart the way one would for cleaning. I inspected slide and receiver.......everything looked good. Cleaned off the factory oil and lubed the pistol with Lucas Extreme Duty gun oil. Took the 15-round magazines apart and cleaned inside and outside too. They felt a bit tacky out of the box. I used the medium backstrap for this pistol. It was a bit more hand-filling than the small backstrap.

At the range I used the NRA 25 yard slow-fire pistol target, NRA B-16. I shot from a rest at 15 yards. I started out with 50 rounds of Federal HST 147gr JHP, then 100 rounds of MEN German made 124gr NATO FMJ and finished up with 50 rounds of Speer Gold Dot 124gr JHP standard velocity. All 200 rounds fed, fired, and ejected perfectly. The primer strike was centered and more than sufficient indention. The ejected brass landed about 6' away around the 4:30 position. No brass to the face. The brass was in a neat little pile just like my Beretta M9's ejection pattern.

This is a traditional DA/SA action. The DA pull was long, but consistent through out the length of pull. The SA pull was a bit on the heavy side. The break came when the trigger was almost to the receiver. I finally got over the feeling of "is this hammer ever gonna fall" and found the SA more friendly. I did shoot 15 rounds DA only and found that my accuracy was as good as shooting the pistol SA. I came away with the feeling that a DAO platform with a "D" spring would be close to ideal for me.

I know much has been said about the rotating barrel and recoil mitigation. I did the find the pistol's sights settled back quickly for the next shot. Recoil was not an issue at all. And I didn't feel tired after shooting 200 rounds. I only had the 2 magazines that came with the pistol. Definitely going to order more mags and a holster.

Compared to my Glock 26 gen 5, the Beretta is a bit more chunky. But for carry I am partial to a hammer fired pistol. I learned to shoot with a S&W model 19 so that influence is still there. The slide mounted decocker/safety is another thing I like. At least one has the option to use it or not. It was a great day at the range. I look forward to many more with the PX4!!

A G26 would be more fairly compared to a Px4 Subcompact. Check out the thread link below to see a good comparison. Granted, the Subcompact doesn’t have the rotating barrel because of its stubbiness but you can definitely sweeten up the DA/SA action with LTT offerings.

I came across a stock LNIB Px4 40S&W at my LGS/feed store, ( https://livengoodfeeds.com , Lockhart TX), at an exceptional price that I now own. Thank you GJM for your G23 Gen 5 thread. I’m pretty sure I’ll never need bear medicine here in Central Texas but I’m not letting get that in the way of being prepared for it. Already converted it to a G and swapped out the stock hammer spring with a LTT 11#. Started shopping LTT and the Beretta websites for fugly decock levers but are showing out of stock on LTT and I’m not seeing them on Beretta. Have they been discontinued? I’d also like to note that it isn’t fair that I have to weekly shop at a feed store that has an awesome gun store inside.

The actual fugly levers were a temporary offer, as they were hand made from stock levers. They no longer are offered because the Carry levers replaced them.

Thanks, not seeing them in stock at MGW or LTT and not seeing them listed at all on the Beretta site. Very sad. Have any experience with the 92 style? The stealth levers are stealthy but I occasionally miss a decock swipe due to their stealthiness. The carry or fuglies seemed perfect at they are 100% swipable and are still stealthy.

Wait for the Carry levers, they are excellent. I purchased from LTT last month to replace my Stealth levers.. which I found difficult to use. Rounded edges on Carry version are medium sizes, smooth and easy to use.

No worries, plenty of other stuff needing attention. Will be soon ordering from LTT: Ameriglo sights, competition trigger group, spurless hammer. 10# mainspring hammer and opto trigger bar.

Oh, I’m a believer in the Carry or Fugly levers. Have them on my Px4CC and on my Px4SC that now resides with my daughter and is her EDC. Guess it would be best to accept that it is no longer my Px4SC and it’s her Px4SC.

Yes, we run the model 92 style levers on our PX4 Compact. They are the easiest to operate and are not sharp at all. The only downside is that they are wider than even the stock levers. However, they work great.
They come as type F levers, so you would need to remove the detent ball and spring if you wanted it to be type G.

[That Guy]

Have any experience with the 92 style?

I have them on my full size PX4 and I love them. Very easy to decock the gun even one-handed, even with my small hands. With my OWB and IWB holsters, while the levers do make the gun wider it has made zero difference in concealability as far as I can tell. (Sorry, I'm not one of those cool kids who have AIWB holsters, so I don't have an opinion on how well or poorly the 92 style levers work with that carry position.) Your milage may very well vary though.

Any negatives with the 92 style levers? Well, mine were the type that work as safety levers so I had to push out the little steel ball and its spring in order to turn them into decock only levers. And the gun is in danger of getting the nickname 'Dumbo'. :) Other than that, not really, at least in my opinion. It's possible that with some holsters designed around the stock levers, there could be fitment issues with the wider levers, but so far I haven't run into any. Even my Safariland SLS holster clears the 92 style levers just fine.
