Sig P365X vs Glock 43X?

[Runt1122]

Who has experience with both? Which do you prefer? Difference in shooting characteristics?

[RJ]

Owned both, vastly prefer the P365x.

Both of mine were reliable and accurate. Flatness of the designs is very easy to conceal AIWB.

G43X had an SCD, not available on the Sig (albeit the SCD maker ceased production this year, so you can’t buy a new one anyway.)

My G43X was awfully snappy. For some reason it just smacked my palms. Even a Glockstore Tungsten guide rod didn’t help. I sold it without looking back.

I picked up my P365x fairly recently. It has a useful 2 more rounds in the mag. Takedown does not require a trigger pull. Modular FCU allows easy swap of various grip options. It direct mounts a Holosun 507k/407k with no plates. The flat trigger breaks right at 90, for a crisp feel. I like it quite a bit.

[4RNR]

Owned both. I preferred the 43X but sold it in favor of the 365XL. For whatever reason I couldn't shoot the 43X straight. I rented one before buying and loved it. No issues, very accurate. Had a gunsmith look at mine just in case and nothing....no obvious issues that would cause accuracy problems. Others shot it and didn't have this problem. Ultimately I found that I need to have my finger all the way in almost using the crease between the 2nd and 3rd pad to get any kind of accuracy

If I run into a used one I may give it another shot but I'm not spending that kind of money again to possibly have accuracy issues.

Have both, but carry the 365x with a 407k daily. And I have toted glocks for decades. Still carry a g4 g23 on duty.

The 365x and xl really do have some weird magic built into them. They shoot softer than expected for the weight. The factory trigger is surprisingly good (though different coming from glocks) as well. Comes with night sights from the factory and easiest optic mounting in the business. I liked being able to swap the grip modules when I go to 10 round states also.

Still gonna have the 43x milled for the same optic (to do an apples to apples comparison) but it may be hard pressed to displace the 365x or xl as a daily carry. The only thing a dotted 43x will have over the Sig’s is a real rear sight to back up the optic. Though the nubbins on the holosun actually do work just fine as back up irons.

Note : Dot pic was taken in a steady rain with my older iPhone.

[Up1911Fan]

P365X hands down. I've been a Glock guy for 16 years, but much prefer the 365 series to the 43/43X/48.

[davisj]

I’ll be the contrarian, 43X for me. I have two, one is milled for a 507K and the other will be eventually. Had a 365X for a little over a month and had a 507K mounted to it. I liked the direct mount and loved the trigger but the grip was too skinny and too narrow front to back so there was zero room for my support hand. Both recoiled about the same for me.

Just traded the 365X for a 320X Compact because I really liked the flat face 90 degree trigger. So far I’m a fan of Sig’s G26X. :)

[YVK]

Never had a 365x but did own a 365XL and preferred 43x/48 on every account.

[tlong17]

I feel the Sig is superior in this category for me. But, the gun doesn’t really matter.

[GJM]

Never had a 365x but did own a 365XL and preferred 43x/48 on every account.

Did someone hijack YVK’s account — thought you carry a 365X daily now and are selling your 48?

[YVK]

I thought 365x was with a longer grip? My daily is 365MS with optic slide that has a superior concealment factor over all of them while being acceptably shootable.

[Navin Johnson]

If one has spent more than six or seven minutes on the internet researching they would find that both of these seem to be good products.

Probably best to match it too something that you have familiarity with shooting already. And then add in feature sets.

In my experience most ranges have both available to sample.

Otherwise on an open forum opinions are likely to be subjective and not objective. As always YMMV.

Good luck!

[GJM]

I see why that is confusing. To me, a 365XL means the length of the slide, since the grip modules are so easily interchangeable. A 365X to me, means a 365 length slide that is optics cut, regardless of what grip module is installed.

[sickeness]

I’ll be the contrarian, 43X for me. I have two, one is milled for a 507K and the other will be eventually. Had a 365X for a little over a month and had a 507K mounted to it.

Just FYI, it is extremely easy to mill the 43x/48 MOS yourself if you have the desire to do so and the right tools.
I did both of mine by taking off the finish with a diamond file, dimpling the center of the rear post and using a 1/8th carbide drill bit.

Took about 20 minutes each going slow and carefully, there will be some finish missing but its hidden under the optic so who cares?

[KevH]

No comparison. The 365XL all day long.

[Biggy]

I have had a G43X with Shield Arms 15rd mags and a P365X and a P365XL. I sold them all and now prefer and carry the Shield Plus 3 inch and 4 inch barreled model pistols.

The X is the regular slide on a XL frame. It's like saying Glock 19X.

I have experience with both 43/43X/48 and P365/365XL. I used to carry a G48 or 43X but now carry a P365 MS (occasionally a P365XL MS) daily in retirement. The guns are smaller, hold more rounds, are reliable and accurate and have less perceived recoil. I have replaced the SIG green factory front sights with yellow outlined ones which makes a big difference. It took me a while to buy another SIG as everyone I bought over a period of 10 years or so had some sort of malady. They were sent back for repair then sold.

I still strongly prefer Glock in the larger sized pistols and you could not give me a P320. I wanted to try one but the drop safe-related concerns, and bent ejector issues have kept me far away. Based on what I was seeing on the P320 it took some time and a lot of research to even try a P365 last year. They have a different FCU and have had none of the reported P320 problems (when released years ago, the P365 did have their own set of problems, which by all accounts have been remedied). I still have concerns in the back of my mind about the gun being fully cocked and able to discharge if the striker were to break in a certain way, bypassing the firing pin safety. I have heard of no instance of this occurring and there are enough of the guns in use, and been tested and approved for LE use, that if this was a problem we would have heard about it long ago.

The P365 mags are as durable or corrosion resistant compared to the Glock and are a lot more expensive.

[sparkyv]

I'm SHOCKED that so many on this forum post prefer a SIG over a Gluck for CC!


I've experienced both and for many reasons chose the SIG. This alone is reason enough for me:

Takedown does not require a trigger pull.

[newyork]

Are you limited to certain optics on the 365 platform? If so, which optics? Rmrcc possible?

[RJ]

My one minor knock, based on one P365XL, one P365, and now a P365X, was in fact the magazines.

I took my P365XL through one USPSA Production match to see how it would do, and if anything odd showed up. Reloading a dropped mag after a stage, I noticed the follower had barfed out the top of the feed tube lips. I stared at it for a few seconds, then shrugged and stuffed it in and reloaded. This problem never recurred. I took all the magazines at home and found that it was pretty easy to remove the follower out of the top of the mag with light pressure using a plastic Tipton pick. This was true for all the P365 pattern mags I had (a bunch). Obviously this isn't normal use to pry on the follower, but I do believe the design is susceptible to spontaneously ejecting out of the top of the mag, but only say dropping them partially loaded at e.g. a USPSA match. To be honest I doubt most are dropping partially loaded P365 mags, given it's primary use case as a very concealable 10/12 round EDC. So this may be a moot point.

As to corrosion resistance, I treated my mags with Eezox, based on accounts I read here and elsewhere of rust on feed lips. Same for the mag catch; treated with Eezox. Whether or not it was due to this treatment, I did not have any rust issues on mine, at all (I live in FL, fairly humid).

Can't argue they are more expensive. So far the best prices I've found on the Sig mags is at Osage County Guns at $34.89.

https://osagecountyguns.com/sig-sauer-mag-365-9-12.html

I've never had either of these issues with any Glock mag.

I've experienced both and for many reasons chose the SIG. This alone is reason enough for me:If I can test fire the gun first I would probably still be with the Glock.

That being said these guns are not my edc. More like a compromise when I have no other option

I really think SIG would have a winner using the P365 FCU as the basis of a new line of full sized pistols.

[RJ]

Are you limited to certain optics on the 365 platform? If so, which optics? Rmrcc possible?

Others smarter than me can comment, but I believe the standard footprint on the X platform is the Shield RMSc. (So, Sig Romeo Zero, Shield RMSc, Holosun 407k/507k* are a direct screw on to an X slide).

A Trijicon RMRcc will not fit; I believe it has a unique footprint.

*These fit an X slide, but the Holosun footprint is a slight modification of the Shield footprint; the two rear sockets are missing and the sockets in the front are shallower. The 407k/507k still screw right on the P365x though.

Here's my 407k red 6 MOA dot going on my P365x. I really like this as a carry gun.

Thank you. Would rather have seen more compatibility maybe with plates or something but I get with the size of the slide it’s possible.
If the rmrcc were doable it’s make me pay more attention.

[RJ]

Eh, I dunno; I'm not, really.

Most of the folks here are experienced enough to give you honest reflection, good or bad. If they tell you they prefer one or the other, it's usually a well-grounded opinion. A thing about pistol-forum I've always liked is you get what you need to hear, not what you want to hear.

[HeavyDuty]

SIG improving the Romeo zero into a reliable, durable sight would be a total gamechanger for the P365.

[BillSWPA]

The RMRcc can be used but requires an adapter plate which must be purchased separately. It also does not have a backup rear sight built into the optic. I would still give this optic serious consideration if/when I get a P365XL.

I don’t have a technical analysis for you. I’m going by what I have read here on P-F from people who have the experience and knowledge to make the call.

[Zincwarrior]

P365X hands down. I've been a Glock guy for 16 years, but much prefer the 365 series to the 43/43X/48.

As a note i've RO'd multiple people with 365s in Waddle and Shoot competition (IDPA). All of them have been far more accurate with them than other shooters with comparable sized pistols. They appeared accurate to 15 yards, vs. 7 yards for comparables as a reference.

[GJM]

I am genuinely curious. Often times things get repeated here, and on other forums, and then move from opinion to fact.

I am not aware of any significant design differences in the 320 and 365 FCU that would suggest one is more or less safe or reliable. Of course, I am not technically savvy enough to appreciate those differences unless they are pointed out to me. I do know that Sig had a lot of trouble with the 320 early on. The 365 benefited from coming later, and having had the 320 suffer the growing up pains that seem to often come with new Sig designs.

They are certainly a bunch of 320 and 365 pistols out in circulation these days, and I haven't been hearing much chatter about systemic design failures that lead to safety or other issues, beyond the normal stuff that breaks, wears out or is poorly manufactured.

All equal skill making several runs with each platform on the same day on same COF?

HCM has posted about the 365 having less problems compared to the 320 and not requiring a special SKU in his agency. Hopefully he will post and clarify.

[octagon]

To the OP questions having owned and shot the Glock 43/43X and 48 and compared them to the 365 and 365XL with various slide and grip frame swaps between all variations I eneded up going with the P365 and XL over the Glocks. As already mentioned the Sigs shoot softer than the Glocks. The interchangability of the Sig FCU and grip modules is a factor the end user may or may not find important. I do because of replacement ease, cost and stippling/grip texturing. The grip angle of the Sig makes for a shorter height gun that allows for full grip of all fingers on the frame while being shorter in overall height. The Sig grip texture is better in my opinion than the Glock but both can be improved easily enough. Coming from carrying Glocks on duty for 20 years and off duty for almost 30 years the grip angle of the Glock is natural and comfortable for me but experience may differ for preference. That said transition has not been difficult. I don't use an optic and with MOS versions of the 43X and 48 it seems a non issue anymore.

Two factors that the Glocks have in their favor over the Sigs for me is the ease and simplicity of working on and diagnosing issues with the more familiar and simpler functioning design. I can disassemble and re-assemble a Glock blindfolded in minutes. The Sig is more complicated and challenging to fully disassemble even with video and paper manual. This may or may not be an issue depending on the end user skill,knowledge and experience with either or issue that may or may not occur. The other is the Glock's frame size and shape as it relates to magazine button makes it the best fit for me than any other gun I have shot including all other variations of Glocks. I find the Sig mag button not as easily or comfortably pressed due to it's location,size, shape etc.. That again can be user specific.

As an added factor I have used and own 9 Shield magazines for Glocks and have had zero issues with them.


The issue of the differences and preference between Sig P320 and P365 FCUs that I am aware of is the bore axis height, material and method of FCU frame construction and safety history.

The 365 allows for a lower bore axis than the 320 FCU. To some that doesn't matter to others it is very important. The 320 FCU frame is thinner stamped steel sheet metal design where the 365 is a machined thicker steel design. That hasn't seemed to make any difference in durability,strength or reliability just an observation. Lastly the 320 has known and documented drop safety issues in early iterations. The 365 has had no drop safety issues that I have heard but did have striker and out of battery functioning issues.

I think both the slimline Glocks and the Sig 365 series guns are excellent guns and wouldn't feel uncomfortable with any of them as my EDC or only gun for concealed carry.

I too really wish Sig would offer larger models of the handguns using the 365 FCU for slimmer guns with lower bore axis height and interchangeability of frames,slides and magazines.

[4RNR]

I really wish someone would make 365 grip modules. I think there's an untapped opportunity there.

I would prefer a different grip.

I’m surprised Wilson Combat hasn’t stepped into the 365 grip module arena given their relationship with Sig on the 320. I’d think the volume of 365s in the wild would be an incentive. 🤷

Living in Florida, I wear a T-shirt & shorts pretty much every day. I liked the 43/43X/48 to carry, but never liked shooting them much. Even though I was real comfortable with the 19 & 26. I liked the 365 right away. When the longer gripframe came out, I knew the 365X/XL was the answer for me. Shooting timed drills confirmed for me that the little Glocks suffered in comparison. Now I have two 365’s, set up as an XL and an X with a PMM comped barrel, both use the XL holster. And I have a pile of carry guns I never look at.

Man you guys are tempting me to spend ~$1,500 (California Tax) to buy a 365XL :( If I like it over my G48, it would get sold for about $1,300.00.

[octagon]

I'm not sure what others are looking for in frames for the 365 and XL but I would like to see a touch longer front to rear grip like the large backstrap hump already available but with slight palm swells and/or longer length that could accommodate 12 round magazine with slight extension and still be flush or the standard 15 round mags and stick out slightly. Because of the 15 round extensions extra width a slightly larger magwell would be necessary and might be nice for the extra width in palm swell and backstrap length.

The icarus frames do nothing for me as they are metal versions of the factory grip module for the most part. Unless you are looking for weight or regular acc rail I don't see any benefits. They don't offer any added grip texture,shape or palm swell. Same with the laser or other grip textures. Few offer much significant improvement or that an end user couldn't do easily enough. Since factory grip modules are so cheap and easy to swap out trying some home made stippling, texturing or silicon carbide treatment are much less risky like non modular designs should you screw it up.

One should also consider the Shield plus if it is an option for you. Have not shot my 43x since I got the Shield. I have less than 100 rounds through a 365.....like the Shield best personally.

[GJM]

I think the Shield handles +P ammo the best of the three. Love the texture and trigger. Magazines are an issue if you want to load 13 or even get more mags easily. Optics requires direct milling to get a Holosun K on.

The Glock is resistant to corrosion, holds ten in the ten round magazine, easy to work on and has all the virtues and vices of a Glock.

The 365 series rusts more (gun and magazine), has awesome accessory support, great magazine options and capacity, and is the easy path for using an optic.

I think they all are attractive, and make a great slim line if you use that platform for your larger gun.

Trijicon makes the plate. It should be available from most dealers who sell the RMRcc.

Regarding the reliability of this or any other optic, I currently own exactly one pistol mounted optic, and have not had the chance to shoot the pistol since mounting the optic, so I will have to defer to others. However, if I am potentially betting my life on a piece of equipment, I will take American made over made in China.

[D-der]

A couple of weeks ago I put a Talon Pro
kit on my XL Razorback module and I'm
quite happy with the results.
I was wondering how the adhesion would
be to the rougher texture but, no problem's
yet, I did make a couple of wedge cuts above
the camel hump on the back strap to avoid
wrinkles and heated it up several times.
It added noticeable circumference and improved
grip considerably.
I'll see how it holds up but I think the end result
is a keeper.

[HeavyDuty]

If I wanted to mount a RMRcc on a P365, I’d be looking at direct milling instead of using a plate to keep the dot low. But I don’t think that’s an option with the P365X and XL.

[newyork]

Yeah I was thinking about that myself. Seems all x and xl are optic ready. Seeing a pic of the rmrcc on an xl shows it sitting pretty high. Irons or bust I guess.

[RJ]

Who makes that rmrcc plate?

Is the Romeo Zero not reliable? Where is it made?

The ROMEOZero housing and lens are made of polymer. It is not IP (ingress protection against dust / water e.g. IP67) rated. It will not withstand rough treatment, such as Aaron Cowan's "drop tests", which Holosun and Trijicon (among others) optics pass. Sig offers a metal shroud as an accessory.

The CR1632 battery is bottom mounted, requiring removal of the optic to replace, so every mount/unmount has the potential to damage threads or over torque the 9 in lb screws. The optic may or may not need to be re-zeroed.

It uses a single brightness button to manually set any of the 8 brightness levels, either up (blinks 5 times at max) or down (blinks 5 times at min, then the logic changes back to "up"). Some report issues with the ergonomics of the location of the button.

The 0.050" allen wrench windage and elevation screws lack tactile or audible feedback "clicks", common on almost every other optic sold. The user has to estimate amount of turn to move POI to POA inside a 120 MOA range of motion of the screws.

From observing discussion on another Sig enthusiast web-site over the past year or so, R0 users seem to report less than expected battery life, the lens scratching easily, fails for the dot to work (as in not work out of the box) and fails to be able to adjust the dot, at all (as in the windage and elevation screws do not move the dot). Sig's customer service and the 5-year limited warranty on the optic seem to resolve issues satisfactorily.

It appears the R0 is made by the Huanic Corporation in China:

https://www.huanic.com/index.html

According to one source I found:

"Huanic is a leading reflex red dot OEM in China. Huanic OEMs reflex red dot sights for Holosun (owned by Huanic), Sig Sauer, TruGlo, and likely a number of other brands. Huanic also owns Surpass Technologies, a US-based importing company that receives a number of shipments of red dot sights from China, likely as part of their OEM operations. Huanic is a technology innovator for reflex red dot sights, pioneering the use of extended battery life circuitry including low-power LEDs and motion-activated ("shake awake") illumination."

It would seem to me the issue(s) with the R0 would be with the specification Sig Sauer provided to the manufacturer, and not anything to do with the country of origin. The R0 is one of the lowest price points for a pistol-mounted MRDS, and it shows.

[newyork]

Thank you. A definite PASS. I’d like to try out someone’s 365xl at some point. Has my interest. Not into the optic choices but that’s fine as this is just a minor interest so far

GJM's summary is spot on, as usual. I don't have the extent of exposure to multiple firearms that he does, but my list of pro's and con's I did before settling on the P365x was very similar:

Shield Plus Optics Ready (sku 13534) with 13 round mag: Pro: Best in class oz/round (2.1), very shootable, RMS-c optic ready. Nice trigger. Con: too big for pocket carry, did not prefer the pinch hazard for the 13 round mags. With 10 round mag: 2.5 oz per round, pocket carryable-ish (not 100% sure with optic).

Glock 48 MOS: Pro: It's a Glock. GSSF Pricing. RMS-c optic ready* (*HS 407k/507k requires slight mod to slide.) Soft shooter. Con: It's a Glock. Previous so-so experience with a milled G48 failing to chamber carry ammo. The SCD is no longer in production, so putting on a Gadget to thumb the "hammer" holstering isn't an option these days. 2.7 oz/round is at the high end of the thin 9mms in my list. Mag capacity can be addressed by use of Shield Arms 15 round Gen 2 mags and replacement of the polymer mag catch with Shield Arms steel one.

Sig P365x: Pro: Thin. Mild recoil. 2nd in group oz/rd, tied w G19 (2.3 oz/round). RMS-c ready. Positive previous experience w P365 and P365XL. No suppressor height sights required; can keep existing front sight with optic mounted. FCU design = many modular grip options, including the ability to turn it into a 10 round P365 (and the 12 round P365x magazines include baseplate to make them 10 rounders). OEM 15 round mag option. Flat trigger. Stock night sights. 78% of the weight of a G19 rig. Con: It's a Sig, don't drop it. (kidding! :cool:)

I’m in a ban state (10rds) but like the xl sized grip. I see thy sell the xl with 10rd for ban states. The smith is interesting since I shoot smiths as my go tos. But I’m not a fan of the short grip. So the 365xl is appealing. But I’m not interested in holosun or rmsc. I’ve been using dots and getting used to them (rmr) but I’m not opposed to having an irons carry.

[HeavyDuty]

I personally wish SIG would do an XL version without the optic plate.

[JCS]

Thank you. A definite PASS. I’d like to try out someone’s 365xl at some point. Has my interest. Not into the optic choices but that’s fine as this is just a minor interest so far

What’s wrong with the Holosun 407/507k?

It has a bigger window than the Aimpoint ACRO and mounts directly to the factory slide, no plate needed.

I know ppl love em and I have a bunch of made in China stuff but I try to pass on the Chinese made optics if I can. Just from reading here and other forums it seems they’ve had more optics go back compared to Trijicon of late. No way to really know that but I’ll stick to non Chinese. I’ve tried to let that go in the past but i just can’t get past it.

No firsthand experience, but my understanding from others on this forum is that the 407k and 507k have a rear sight built into the body of the optic which will result in reasonably good accuracy with the standard P365 front sight, providing a backup sighting system in the event of optic failure.

Regarding my P365XL MS I wrote this in a PM to another member this week...

"The stupid little gun shoots so well I have a hard time justifying carrying just about anything else off-duty other than situations that call for a super light (340SC) or super small (Kahr P380) situation. I'm kind of doubting guns like my P228, P239 or Glock 19 will ever get carried again."

I had mounted a 507k on mine, but went back to irons because I felt it just made it too bulky for what it is and I have no problem shooting with the factory irons on the gun out to 50 yards. Just in case anyone is interested, the Holosun built in backup sight works perfectly with the P365XL's front sight.

[vandal]

This is where I'm at. I had the opportunity to shoot a-c steel at 200yds. Once I found my holdover it was easy to get hits with the P365XL Razorback/507K, six out of 10 shots. I've been a G19 guy for decades and then tried the same with my G19.5/508T and only managed 4/10. Both have PMM barrels/comps on them.

Only thing I can't currently do with the P365XL is carry with a light in a Tenicor holster. I've been surprised at how long it's taking to get holster support for the P365 with TLR7-Sub or Surefire XSC.

Had a problem with the magazines and mag catch rusting from sweat after a run. Coated the mags with Alumahyde II and replaced the mag catch with an aftermarket stainless/nitrided one and no rust since.

Previous to the P365XL I carried a G48/507K and have zero regrets.

If I wanted to mount a RMRcc on a P365, I’d be looking at direct milling instead of using a plate to keep the dot low. But I don’t think that’s an option with the P365X and XL.

After looking at a variety of mini dots, I chose the RMRcc for my P365.

I sent my standard slide in to be milled by Culper Precision. For $260 (including tax) they cut and cercote. The advantage to having the slide milled for a direct fit is twofold-
- The RMRcc doesn’t need a plate and sits lower
- The rear sight dove tail is retained

Cliff notes- standard P365 plus roughly $120 (milling and XL grip module) will get you a handy 12 shot pistol ready for an RMRcc.

(If anyone is interested in following along as I pimp my P365, let me know and I’ll start a thread.)

That gets you the full grip with short slide ? If you want the long grip and long slide, then the only way is the optics read model where you’d need a rmrcc plate?

If they do a long slide without optic plate, I haven’t found it. I’d prefer that.

All Sig made ones are. And the zev xl slide that retains the factory rear sight is also RMS-c pattern cut.

I don’t know if it works for the RMRcc but supposedly rumored yes.

That would help limit vision block of the window.

I don’t like suppressor height sights on carry guns so getting low with a 507k or RMSc and using standard height fronts have been my go-to on P365s.

Nice! Thanks for sharing!

That would be the way I would go to prevent crowding the already small window. It’s similar to the rear integrated sights of the RMSc type optics.

One thing when people talk about mounting things low… they sometimes forget that different optic bodies have different heights.

RMSc types are the lowest. RMR and RMSc are pretty darn good too.

I think the ears of the IRDS could be taken lower if needed, too.

Anyone here have a rmrcc on a 365xl or 365x? Is it THAT high? It looks to be in a couple pics I’ve seen. Using that chpws rear iron that mounts in the rmrcc would mean you’d need a taller front sight I’d assume if using that Trijicon plate

That's a cool little gadget. I won't need it because the rear sight dovetail will be retained. I don't know what sights I'm gonna use, but that problem is going to be on the back burner until I get the pistol put together and shoot it.

Yeah I did have MapleLeaf mill it. I don’t think I’d be happy with an x slide + plate. Would be too high. These sights are already just barely in the optic window. Maybe a touch more than the nubs on the back of a 507k.

I guess that depends on what your purposes and goals are…

I’ve put an SRO on it before just to goof around.

81635

P365 is such a shootable gun that you can use it like a larger gun.

Which sometimes means a larger optic.

Personally the RMR is just mounted on it until the new RMSx comes in. Then I’ll probably do that.

81636

I like the light sensor on the RMR better than most Optics.

So if you to keep it in objective comparison.

Even with adapter plate, the RMR on a P365 sits close to where a direct milled Glock with 507c is.

81639
81640

And definitely no higher than a direct milled Leupold DPP on a P01.

81641

Personally, I’ve run all kinds of different height Optics on slides including dovetail mounts and I don’t notice a lick of difference in function or shootability.

Personally if you care about height than the only answer is an RMSc or 507k.

That’s fair regarding Holosun.

Shield RMSc is made in Britain if that makes any difference to you.

My personal carry gun is set up with the 8 MOA RMSc (because I like the light sensor).

And yes, that’s the SAS.

When it’s not quite lined up you don’t see the halo.

I use it like a “Green dot.”

These were my first shots with a P938 SAS that prompted me to get the SAS in P365.

[newyork]

Wow! Looks like those work great! I had no idea Shield was British btw. Are they durable enough for carry?

[luckyman]

I have experience with both 43/43X/48 and P365/365XL. I used to carry a G48 or 43X but now carry a P365 MS (occasionally a P365XL MS) daily in retirement. The guns are smaller, hold more rounds, are reliable and accurate and have less perceived recoil. I have replaced the SIG green factory front sights with yellow outlined ones which makes a big difference. It took me a while to buy another SIG as everyone I bought over a period of 10 years or so had some sort of malady. They were sent back for repair then sold.

I still strongly prefer Glock in the larger sized pistols and you could not give me a P320. I wanted to try one but the drop safe-related concerns, and bent ejector issues have kept me far away. Based on what I was seeing on the P320 it took some time and a lot of research to even try a P365 last year. They have a different FCU and have had none of the reported P320 problems (when released years ago, the P365 did have their own set of problems, which by all accounts have been remedied). I still have concerns in the back of my mind about the gun being fully cocked and able to discharge if the striker were to break in a certain way, bypassing the firing pin safety. I have heard of no instance of this occurring and there are enough of the guns in use, and been tested and approved for LE use, that if this was a problem we would have heard about it long ago.

The P365 mags are as durable or corrosion resistant compared to the Glock and are a lot more expensive.

How is the manual safety? Is there anything you can compare it to, like maybe a full-size M&P safety?

[JCN]

I had no idea Shield was British btw. Are they durable enough for carry?

So I think this is a philosophical discussion and highly dependent on your carry requirements.

I’m not a mountain man like Clusterfrack so while his enclosed emitter bomb proof irons forward compact is very functional hiking over rocks avoiding cougars, it’d be overkill for me going to the suburban grocery store in sweatpants saying hello to cougars…

I don’t have a high impact resistance requirement for my carry gun optic, it just has to be reasonably durable and vetted (Shield is one of the original RMS companies) as long as I have good BUIS.

I think of my carry optic as irons+.

If it helps, the polymer bodied Shield SMS has the following description on their website:

The RMS is the natural evolution of the SMS which has over 15,000 units in use with the British regular army and Special Forces, as well as US, Australian, New Zealand Special Forces and other NATO forces. Also used by competitive sports men and women across the globe.

The SMS was designed originally for use with pistols and has since evolved into an all round combat optic, used intensively in war zones all over the globe.

They also make a waterproof, stronger housing one called the RMSw but the window is a little smaller.

I work in construction but like 30% of it is rough in and attic and crawl space. 70% is pretty easy going, at worst dusty. The 30% is running wire and hammer stapling, drilling etc. rmsc sounds like it’ll be fine to me for sure. Glass lens I’d assume is smarter.

[HeavyDuty]

How is the manual safety? Is there anything you can compare it to, like maybe a full-size M&P safety?

Not directed to me, but mine is very positive but small. Much stiffer than my M&P45c’s manual safety. I think it is appropriate for the type of pistol, and I’ve never had a problem manipulating the lever - but you’re not going to be riding it 1911 style. I’m actually surprised no one has started offering a slightly larger lever to make the XL more of a thin, compact utility holster gun.

I personally have the polymer lenses and haven’t had issues so I wouldn’t say it’s a big deal either way if you find a deal on one.

Midway USA has the polymer lens 8MOA RMSc for $345 currently.

Yes auto adjust only but it’s very good with the 8 MOA dot. With the 4 MOA I wish it was a little brighter.

I just looked and Brownells has the glass lens 8 MOA RMSc on clearance - I personally would never consider the polymer lens versions. Part of me is tempted, but I’ve pretty much standardized on the RMRcc and RMR for concealment pistol optics. If I hadn’t, a RMSc on a P365x or MOS 43 would be the easy button.

[newyork]

My polis top dot experience is limited. 2 rmr over the past maybe 9-12 months. Low round count. 2 matches, a class and some range visits (6-8). Don’t shoot much lately but it’s increasing. I’m learning the dot. One thing I don’t like is the auto adjust. I’ve found it to be not bright enough on the few times I forgot to reset manual mode. I could see 8moa being better at it. Mine are 3.25 and 6mo
It’s likely I’m being unrealistic and picky with not enough experience. I’ll keep an open mind. It’s torture that the 507 is so cheap.

I like the RMRs and have probably 8 units. But I have probably 30+ Red dot optics from 7+ brands / models and I don’t find any issue going between different types of dots.

The issue I had with the RMScc was the lack of integrated BUIS but the CHPWS solution you use solves that issue nicely.

I have probably 60k+ rounds on pistol red dots in the past 3 years and have tried almost everything.

I think the 507k with the full circle dot reticle is fantastic for rapid sight acquisition on a micro gun.

Great shooting and video. I went through this battle twice when deciding on my first dot. I wouldn’t let myself go Holosun. I’ll think about it. Can’t get past the not only Chinese made , but Chinese owned aspect.

I did try a circle dot holosun in red at a class. Sun was going down. Was on a shadow systems. Didn’t like the gun or the optic. Seemed super grainy. Could’ve been turned down a lot idk. I wasn’t expecting a circle fot so that threw me after shooting a 6 moa dot all day.

Ok I’m hijacking. I’ll leave the thread for others to continue. Sorry.

[SWAT Lt.]

How is the manual safety? Is there anything you can compare it to, like maybe a full-size M&P safety?

I like the safety just fine although I might prefer it to be just a little bit wider. That said, I have never missed the safety when deactivating it nor have I experienced the discomfort to the hand at least one reviewer I am familiar with has. It is unobtrusive yet easily accessible. It is very positive and clicks on and off, more so than the full size M&P 9 I had that I thought was a little soft. I have never had the safety disengage itself while I was carrying it. I would not be interested in a P365 that did not have the manual safety, especially for appendix carry.

[D-der]

I ran a SMSC on my 365 XL at first...because it was what I could get (overlooking the Zero).
I did like the 4moa dot and the light sensor functioned quite well, and had no problems
but changed when the 407K became available because of durability, I carry 12+ hrs a day
whether at work, running a chain saw, under a car, doing yard work etc.
I did just swap to a 507K a couple of weeks ago, preferring the smaller dot.

The flip side is kind of like the iPhone, there’s just not really a comparable product out there.

Here’s my reasoning:
Physically bomb proof: RMRcc and 507k.
Light sensor: RMSc. The RMRcc has the SRO light sensor from what I hear not as good as the RMR.
Low profile to use factory front irons: RMSc and 507k.
Humongous reticle which makes shooting at close to medium distances VERY fast: 507k.

I think most newer dot shooters would learn speed better if there was a humongous reticle. It gets a little technical of a discussion that we can split off, but with a less developed index a larger window or a larger reticle helps compensate.

It’s too bad the rmrcc didn’t fit the cut out. Asking my local guy how much a 365xl from him. We’ll see. I’ll either get one or just wait.

The issue I had with the RMScc was the lack of integrated BUIS but the CHPWS solution you use solves that issue nicely.

I’m actually trying to get by with no irons at all right now - the IRDS is my fallback if I ever decide I need BUIS.

I think that’s reasonable. I don’t have BUIS on many of my optic guns and none of my competition guns.

I kind of like the extra reassurance that I can double check my zero on the fly with good BUIS with my carry gun.

It might be one of those things when you decide you need BUIS you might wish you had them RIGHT NOW. :D

My reasoning is that as a civ, my need to take a shot beyond 20 or so feet is limited. At those distances I’ve found I can get by in a pinch with the RDS frame.

I think that’s probably correct and you’re a good enough shooter that you could make do.

My counterpoint to the reasoning is the scale….

At 20 feet on a full size target that’s not moving you could do XYZ without a dot.

But at 20 feet on a half size target or a head shot (a la body armor) it scales out to the equivalent of 40 or 60 feet.

Add in movement and / or innocent bystanders and you’re looking at trying to confidently hit a 3” target at 20 feet at speed.

That’s my mental math. But I’m with you and that’s why I feel like it’s “good enough” sometimes to carry the SAS.

All Sig made ones are. And the zev xl slide that retains the factory rear sight is also RMS-c pattern cut.

The optic cut P365 series are cut for the RMS-c optic pattern. The P320 series are all cut for the DeltaPoint Pro optic pattern.

I am genuinely curious. Often times things get repeated here, and on other forums, and then move from opinion to fact.

I am not aware of any significant design differences in the 320 and 365 FCU that would suggest one is more or less safe or reliable. Of course, I am not technically savvy enough to appreciate those differences unless they are pointed out to me. I do know that Sig had a lot of trouble with the 320 early on. The 365 benefited from coming later, and having had the 320 suffer the growing up pains that seem to often come with new Sig designs.

They are certainly a bunch of 320 and 365 pistols out in circulation these days, and I haven't been hearing much chatter about systemic design failures that lead to safety or other issues, beyond the normal stuff that breaks, wears out or is poorly manufactured.

Isn't the FPB design on the 365 different? I haven't had a 320 apart for some time, but I remember the FPB lever being different than the one that's on the 365. That's technically not even part of the FCU, but it is a design difference.

I really like the grip size of the 43x/48. Even the larger Sig grip feels tiny in comparison. The Boresight Razorback helps, but I still prefer the 43x grip. I also like having an SCD.

The choice for me is a glock with scd and grip reduction or a 365 with thumb safety. I really like the 365 X and XL but have been trying to get away from thum safeties.
