Help with malfunctioning Glocks *Pics* and details (G32.4) (G19.4)

[Steaz]

My Background
Since I am the one consistent variable across both guns lol, I have received professional pistol instruction in the form of about 2 weeks of firearms/pistol at an LE academy (am not and never was sworn), local pistol classes, and advanced pistol with LAV. I also have a Gen4 G19 with over 4,000 flawless rounds and have owned or extensively fired, with zero malfunctions, 10mm and .45 ACP Glocks as well as other pistols (but mostly the Glocks). All this to say, I have an idea what I am doing and am quite certain my grip or technique is not a contributing factor.

The G32 Gen4 Background
New pistol, very recent. All I have done is add some Slip 2000 EWL, then after a range trip wipe it down quick with a rag and apply a little more Slip 2000 EWL.

I am 365 rounds in, all 125gr
50 Prvi Partizan TMJ (manufacture claims 1,540 FPS and I believe them), no malfunctions
100 Speer Gold Dot JHP, no malfunctions
40 Underwood 125gr bonded JHP(Gold Dot Bullet), this load tests on YouTube at greater than 1,500 FPS in a G32. No malfunctions (does not feel hotter than the Prvi, either, and has less flash)
50 WWB FMJ, no malfunctions
125 Speer Lawman 125gr FMJ, 2 bad malfunctions (with different mags)

It's "only" 2 malfunctions, and early on, but I don't believe in break in periods, these are factory Glock mags, should-be-good factory ammo, and bad malfunctions (don't think I ever had to do remedial action with a Glock before these)...and .357 Sig ammo is expensive I didn't want to spend a ton of money proving this gun reliable. ugh

I haven't had this happen before either.

G32.4 Malfunction 1
Second range trip, around the 140th or so round fired through the gun. Speer Lawman 125gr FMJ. Last round out of the mag. Of note, I did a Dot Torture to start the day with no malfunctions including the 5 rounds strong hand only and 5 rounds weak hand only.

Third range trip, over 300 rounds in total at this point, second round out of a different magazine than the first malfunction

After removing the mag (WTF?)

What gives?


G19.4
This one is also new, malfunctioning the same days as the new G32. Did I mention that I am frustrated by this? As above I applied Slip 2000 EWL when new, wiped off and re-applied after the range, nothing else.

It has 355 rounds fired, main point here is most of the rounds were brass case and worked, both malfunctions were Wolf steel case in Magpul magazines and that combination doesn't even feel right when loading by hand. I'm not nearly as concerned with this one since: 1) I have a great G19 already so there's no 'rush' to get this one proven, 2) 9mm ammo is much cheaper to use to 'prove' it and I have much more, 3) Malfunctions were cheap steel in non-Glock mags.

But, WTF?

I am extremely frustrated with this. Am I overreacting? Should I just keep shooting them and see what happens? Anything specific to look at with the guns, mags, ammo, or myself?

[M2CattleCo]

I don't know what happened with the 32 but steel case in Magpul mags is not going to work. It doesn't have anything to do with the gun.

ETA: I see the pics now. With the 32 looks like you have a weak mag spring causing an inertia feed on #1 and a real double feed on #2, which appears to be an inertia feed and the slide catching the top of the case of the second round and tipping it down into the mag. Glock 40s are problematic, I don't expect a 357 to be any different. I would start with some stronger mag springs.

Magpul mags don't feed steel case.

Thanks. I didn't know about issues with steel case in Magpul mags but as I said, they didn't feel or work right even when loading them at home so that wasn't too worrisome...just frustrating in the same range trips as the G32 messing up.


I know the sample size is small, but the Lawman ammo that both G32 malfunctions happened with is the weakest/slowest rated of the four types I have fired. The Prvi Partizan rated 1,541 and the Underwood Gold Dot are both noticeably hotter so it seems weird they functioned buuut I only have 90 rounds combined of those two...and I have fired more Lawman than the others so more opportunity for issues.

[Bigghoss]

My Magpul mags work with Winchester Forged steel cased ammo but there have been enough people complaining that the combo of Magpul and Wolf ammo would also be my first guess as to the issues with your G19. Especially since you didn't have issues with brass cased in OEM mags.

Hotter amo will exacerbate the inertia feeding, try more of it and see what happens. I used to see those very same malfs quite frequently in 1911s. Usually a mag spring problem.

So what's your recommendation? Perhaps a Wolff +10% mag spring and try again?

I need to look into the aftermarket recoil springs/guide rod perhaps as well.

I want to change *something* quantitative right now before I burn through more .357 Sig ammo. I also don't have any more of the Prvi on hand at the moment. Ordered but not shipped.

[M2CattleCo]

Stronger mags springs won't hurt. I don't know what to do with the recoil spring, but I would try one thing at a time to see what it does.

[Steaz]

I dug around the basement and found a couple Wolff +10% mag springs for yadayada G32 13 round. A little swearing, small finger cut/blood, and one marred mag body later, two of the G32 mags have the Wolff springs now.

[fixer]

It looks magazine and/or ammo related to me.

I too notice reliable malfunctions when using steel cased ammo in magpuls. Its so predictable its a great training tool.

Forgot to mention...I have some really worn out 92 mags that are 10 years old on the original springs. If I drop them during training they will rotate the rounds around.

[Nephrology]

I have issues with Magpul mags too. Steel case ammo tends to bind the mags and delay presentation of the next cartridge, causing failures in otherwise 100% reliable guns. I shoot on a very dusty range in the high prairie of eastern CO, which likely exacerbates the problem. No problems with my OEM mags.

[Steaz]

Well mother fuck. Wolff +10% springs...100 rounds of Lawman...1 FTFeed and a couple rounds I could feel the slide barely manage to close and chamber the next round that I know were on the edge of failing.

So...what do I have to do to get a G32 to work?

FWIW the FTFeed this time was solved by tap-rack, so, it was a less severe failure. But n=1 so that might not be meaningful.

G23, and the similar G32’s are the least reliable Glocks. A Glock 31 G4, a G33 or a G35 with a conversion barrel may run better but the Glock and M&P platforms both have issues in .357.

The only guns which I KNOW run in.357 SIG are the SIG P229/226/239 and the HK P2000 / USPC per the 2004 DHS Pistol testing.

My Magpul mags have been fine as training mags and they are the best non OEM Glock mag out there but I would not use them for duty /carry. The magpul mags are all polymer vs the metal lined factory mags. In order to make the mag bodies strong enough magpul had to slightly reduce the interior volume of the mag. Extra friction in the form of steel cases, dirt, etc is enough to cause malfunctions.

Is your 32 new ? If not, what is the round count and when was the last time the RSA was changed ? Is the gun otherwise stock ?

If the round count is unknown the Recoil Spring Assembly should be swapped out.

My G32 is brand new, totally stock, just lubed with Slip 2000 EWL and wiped down between range sessions, it is now at 465 rounds

*Stock except the Wolff magazine springs I put in last night before firing 100 rounds today during which I had one FTFeed and a couple rounds where I could feel the slide stutter while closing which I know was a near-miss

If it’s is new, I would call Glock.

Let's see..
Shoots Privi ok
Shoots Gold Dot ok
Shoots Underwood ok
Shoots WWB ok
Lawman does not shoot ok.

Maybe if you stuck to other brands than Lawman, huh?


Anecdote Alert
Once upon a time the local store got a Deal on .45 Lawman instead of his usual econoball
1911 shooters were standing in line at the gunsmith and he could not figure out what had gone wrong with their guns, many of which he had tuned or built.
The order of Lawman ran out, replenished with WWB or RP and all the complaints vanished.

Maybe. Maybe not. I don't know, I'm hesitant to shoot up Gold Dots and Underwood due to $ and virtually all of my FMJ was/is Lawman...it should be good ammo.

WWB sample size: 50
Underwood: 40
Prvi: 50
Gold Dot: 100

So that's 240 total rounds clean. Individually none of those are enough to say much esp since the Lawman goes 50 rounds into a session before failing so far it seems, but taken together...


The Speer Lawman sample size is larger, I think 225 rounds...3 failures. That is interesting...all 3 failures are with Lawman with fewer rounds than 'the field'

I mostly bought Lawman because it should be good ammo, I like CCI, it should be close to the Speer Gold Dot I mostly intended to carry, and the price was the best of the bunch (which isn't saying much)

I have another 100 rounds of WWB here and a shipment on the way with 250 of the Prvi, if I'm a glutton for punishment maybe I could just shoot those to see what happens...

Magazines.

You either have the wrong mags, wrong follower or they are cursed.

New Glock mags are about $20 each.

These should be 'new' mags they just came with the new gun I picked up this year (dealer ordered from distributor for me). And I put the new Wolff springs in prior to today's failure.

That said, I do have two additional new unopened mags I received last week.

Double check....triple check the followers are correct. You've not mixed the 32 mags with the 19 mags by mistakes.

If the mags are new I would trust the stock Glock spring just fine.

Those simply look like magazine failures and nothing more.

Tuck the suspect mags away and ONLY take the new and unopened Glock mags you have and give them a try.

Good luck....

Definitely didn't mix anything up with the magazines. Not possible.

I suppose the easiest route to take now (doesn't yet involve any outside entities) is to open the two new magazines and shoot up the 350 combined rounds of Prvi and WWB, unless and until I get a similar failure with one of them. Sounds like a plan.

[lordhamster]

I love the 357 Sig round, but I've had nothing but trouble with EVERY single pistol I've tried it in.

I had several Glock 32.4 models that would choke on Gold dot hollow points from Speer directly as well as those from Underwood. I finally found the problem was the feedramp design on the OEM barrel. I replaced it with a KKM barrel and the problems went away... but I just never trusted the pistol after that, and I didn't want to spend what it would take to run 1000+ rounds through it to re-gain the trust.

I had P229 in 357 that would not reliably feed Underwood Gold dots or Remmington hollowpoints.
My P320 was problematic with all sorts of hanging up on the feedramp as well.

I suspect that the bottleneck causes problems whenever there isn't a good enough crimp on the round.

I've just decided to give up on the caliber. If I want something hotter than 9mm, 40 or 45, I'll go for 10mm next.

[Steaz]

What is going on!?!

I almost have to think it's user error but how can that be? I have thousands of trouble free rounds through multiple pistols and tens of thousands through just Glocks (not a ton by some standards I know), but, I can't even load the magazines without having them get all jammed up!

Brand new 13 round OEM Glock .357 Sig magazine that I just ordered and opened to bring to the range today. Follower has a 3 on it.

I literally got rounds jammed in the mag and couldn't get them out easily just loading it after the first mag or two. Rounds would nose dive as I put them and/or rounds lower down would get jammed up along the sides of the mag and be stuck an inch or inch and a half down after I shook the top round(s) out.

Is there like some super secret Jedi trick for loading .357 Sig Glock mags and I just got lucky before?

This was WWB ammo BTW, not the Lawman I had the 3 FTFeeds with before


Does anybody want to buy this stupid fucking G32.4 and 350 rounds of Gold Dots and 140 Underwood Gold Dot and 200 Federal HST? Holy fuck how hard can it be?

Some days man

[M2CattleCo]

Chamber check some of that 357 ammo in the barrel and/or measure with a caliper. It may be too long.

As far as that 9mm not lighting? It looks like a good enough whack with the primer. Put it in a stock HK or Sig and see it lights it. I know it's NATO, but it's still just plinking grade ammo. Just like most military ammo.

I did save that round, and did not try it again in the Glock. I have that same Glock or I could try it in a VP9 or P-01 at some point.

I swore of Winchester ammo several times over the years due to inconsistencies, filthiness, and more bad rounds (mostly that QC should have caught) than all other manufacturers combined...but I just don't learn. Don't buy Winchester ammo!


I have a caliper I can measure it later, but I had all those failure problems with Lawman and now with WWB, what are the odds...but then what are the odds of anything I don't even know where to start with this (I'll measure COAL later with some of that ammo just for poops and grins)

[Steaz]

So, about that. What does the book say for .357 Sig cartridge overall length? (I have some reloading books, need to go dig them out, moved recently, haven't reloaded it)

That V is literally one of the rounds I pictured above. I sampled a handful of the WWB from that open box I put away in frustration at the range and they varied a bit...Win is such crap I swear

https://i.imgur.com/2jV6lQE.jpg

https://i.imgur.com/2MMzEab.jpg

[M2CattleCo]

That could do it.

Is the round nose Lawman?

[peterb]

Isn't the maximum length supposed to be 1.14"? See page 45 for .357 Sig.

No, weird angle and lighting. It's flat point like most 357 sig FMJ

Yeah, that's what I saw when I Googled too (can't find my reloading books).

I tried putting those WWB rounds into the magazine again, lol waaay too long, I don't know how that wasn't obvious to me at the time, because it sure is now. That Winchester is all over the place on COAL with long ones like pictured above way over.

[Caballoflaco]

Not to be too much of a downer about the 32 but ask Chuck Haggard about the damage he did to his hands and wrists trying to figure out why his Departments glock 23's didn't work. Then decide how much time and money you want to invest in this project, and for what gains over a 9mm glock.

I believe it. I have about 1,400 pistol rounds downrange so far this month with nearly 500 of those .357 Sig and a few hundred of those in just a few days (alongside 9mm). When I did a mere ~125 rounds of the Sig per session, 2 sessions in 3 days (alongside some 9mm), I could feel it in my hand afterwards. It wasn't a big deal, but, it was there. That Prvi Partizan that claims 1,541 FPS...and that Underwood...I'd never want to volume shoot that stuff even if I could afford it

[fixer]

rounds getting stuck...clearly that is a symptom of one or more rounds being out of spec in length or case diameter. I've had this happen with 9mm rounds (can't remember the brand). I've also had this happen with certain mags and steel case ammo (px4 and m&p). In the latter case, it was a combo of mag and ammo. There could be an outside chance you are experiencing a tolerance stack issue between mag and ammo.

9mm light strike: I was shooting a lot of wwb this weekend in my G19 and had two bad rounds in about 400. One round had a problem I'd never seen before--the case head was 'salad bowl' shape. concaved heavily. the rear of the case head was also gouged heavily like someone dragged it behind their car Napoleon Dynamite style. I've also had WWB case diameters off spec frequently in the last 2-3 years. This usually causes a death jam where the round is stuck in the chamber. fun times.

I don't suppose that salad bowl shaped round was anything like this Winchester Ranger 147gr Talon (RA9T) I have experienced in the past? It would feed but not fire, couldn't reach the primer


https://i.imgur.com/Vj0dFVk.jpg

[Chuck Haggard]

Mags are clearly failing to feed up.

Could be followers binding, mag tube out of spec, ammo out of spec, springs suck. You appear to have eliminated springs as an issue.

[Steaz]

Well, I got through 50 rounds of Prvi Partizan ammo, all from the same magazine, today. It's 100/100 on the Prvi now. That's...something. oye

I just did a dot torture so that included 5 rounds SHO and 5 rounds WHO, I finished a mag WHO and it had no problem strongly locking the slide back on the last round. That Prvi is hot (mfgr says 1,541 FPS...125gr)

It fired in an HK VP9


*Reminder, this was a Winchester 124gr NATO from the 150 round boxes you can get at Walmart (only about 18 cents per round) that FTFired in a Gen4 Glock 19. Recycled the same round in a VP9 and it worked

[M2CattleCo]

Either an exceptionally hard primer or it wasn't seated all the way. I've never had a problem with Winchester NATO in any Glock, but it could happen.
