P365 XL disappointed

[JTQ]

I understand the recoil spring replacement and such, but I've shot and owned multiple short barreled compact semi autos and NONE of them have failed to reliably function with multiple brands and bullet weights of their respective chambering. A pistol that costs over $500 should function with any ammo it is fed. I simply won't settle for any lesser,especially with a gun I plan to EDC. It has to work no matter what.

The internet gun forums are chock full of examples of G19/G17, HK-whatever, and numerous other guns that won't function properly - when new - with low powered, typically 115gr, training ammo. These are all superb fireams, that come with strong recoil springs, designed for long life and reliable function, that just don't happen to work well with low powered training ammo, when new.

After a couple hundred rounds, nearly all of these guns work fine with the weakest, cheapest stuff you can stick in them, but when new, the weak stuff just doesn't drive the slide.

I am a Glock fan but this one was o POS. I also have one Ruger that was a dud but I have a couple others that are great. And I hear of several problems with the Sig 365s. Guess they all do it but it’s still disappointing when we get a dud.

Everyone makes mistakes... However if you make one you should rectify it not band-aid it.

Normally Refurbs are more reliable than factory new because they are more thoroughly inspected. That is what I expect out of a companies warranty department.

My new standard p365 did the same early on, called Sig they said shoot it more. After about 150rounds it fixed itself. 115gr ammo works fine in mine.

I never had the issue (other than the first 5 rounds out of that bound up magaIne) but I racked it several hundred times right side up, left side, right side and upside down and broke it in on S&B 124 NATO that was 1270 fps out of a Beretta.

That's a pretty broad brush.

A $200 Hi Point usually functions right out of the box...many $2k-$3k 1911s will not.

 

[94045]

By me the 365 run around 550 bux i would expect it to run anything

Ideally they would ask if you preferred Target Springs or NATO Springs but they don't. Manufacturers either spring for the light stuff and except the accelerated wear with full power ammo or spring for the full power and except that it may not be 100% with practice or target ammo (particularly before break-in).
.

My LGS has some of the Lawman 124 +P FMJ (Loaded to match Gold Dot 124 +P) and my club has some S&B 124 NATO I usually use to break in new pistols. I don't usually have issues after they are broken in.

Clean it thoroughly. Put it back together dry. Rack the slide several hundred times by hand. Clean it again. Reassemble it with the usual minimal lube. See if it shoots any better.

I have several pistols known for needing a break in period (DB9, CM9, P32, DE L5, etc.). I always do this with a new pistol and all of these brand new pistols have been 100% reliable from shot #1!

 

[Old Dog]

How many magazines did you use for those 50 rounds, and did it display the same issue with each mag?

50 rounds is nothing for a micro-pistol. I'd render some judgement after at least 250 rounds if there will still problems.

Do you have your strongside thumb alongside the slide when shooting? That's a common problem with these little guys, and it'll definitely induce FTRB malfunctions.

I believe he stated that he was left-handed, so that shouldn't be a factor.

 

[Old Dog]

I meant the slide, and um, yeah, it could be. With the "high thumbs" forward grip, even lefties can have their thumb along the slide. This can definitely slow the reciprocation of slide.

Huh. I'm sitting here fondling my P365 and holding it in my left had and just can't see how the thumb can get anywhere near the slide.

Reminds me of that Parks & Rec episode in which they were trying to design drinking fountain guards since the locals drank from a public fountain by placing their whole mouths over the spigot.

Unless you have an egregiously wrong grip, it shouldn't be a factor.

 

[Trey Veston]

Holding in my right hand, I can see how maybe during recoil my thumb might inadvertently hit the slide release lever...

 

[CarJunkieLS1]

Yes I'm a lefty and I'm 100% positive that my thumbs aren't touching the slide. I used both mags that came with the gun. They are both 12 rounders and both exhibited the failure. It was multiple times per both mags.

I have another brand of 115gr FMJ ammo to try and I picked up some 124gr FMJ to try also. When I get to try both ammo types and if the problem persists I'll be contacting Sig.

Doesn't having your thumb so low on the grip interfere with your other hand making contact with the frame?

I have never had an issue with my grip and use the traditional thumbs forward grip. From Gunsite to GSSF matches to Navy SEAL instructors, no one has ever suggested a change to my grip or indicated in any way that it is incorrect.

 

[JohnKSa]

I think what he's saying is that your thumb position, as shown in that picture, will change when you have both hands on the gun unless your two-hand grip is somewhat unusual.

I don't see how you can get a traditional thumbs forward grip on that gun with your strong-hand thumb in the position shown because that's where the base of your weak-hand thumb would need to be for a traditional thumbs forward grip. Your strong-hand thumb will have to move upward on the grip to make space for your weak hand to get on the gun.

I can tell you that my strong hand thumb position changes significantly when I switch to a two handed grip.

Your thumb seems low to me, though it's possible the OP has the same grip you do and contact with the slide would not be an issue.

This is what I would have expected the grip to be.

Not everyone holds the thumb that low.

 

[Hangingrock]

Maybe SIG should send out each P365 with 200-Rds of ammunition for break in shooting procedures. That would be the DAY, would it not. I did not acquire a Glock until Gen-3 and S&W MP-Gen1 series until just before the introduction of Gen2. I am happy for others to be the Beta Testers.

 

[Texas10mm]

Some 9mm pistols specify 9mm NATO for break in.

 

[murf]

maybe you got a tight gun and have to burnish the frame/slide before it functions correctly. I would take most everyone's advise and either rack the dry slide a couple hundred times, or shoot another couple hundred rounds, or so, before sending it back.

tight tolerances are a good thing,

[sequins]

Sounds like ammo to me. I experience the slide issue you're describing on my 1911 when I fail to apply sufficient crimp or fail to completely resize. I'd try new ammo before I doubted the gun too much. Generally a nice tight chamber is a good thing.

 

[jonb32248]

50 rds in a new gun isn't enough to say there's something wrong. I have had guns that have never had a bobble to others that the first couple mags things happened then cleared up. Dry fire it a ton at home and then shoot it shoot it shoot it. Then after a reasonable time if still is a problem maybe have someone else try it. After that call CS.

 

[340PD]

So today I bought a brand new P365 XL. I took it apart cleaned it and shot it today. I only fired 50 rounds of PPU 115gr range ammo and it would fail to return to battery multiple times per magazine. I could take my thumb and press the slide forward and it was easily fully chamber and would fire. The pistol shot well accuracy wise, trigger was ok and it ejected every single time.

Do you guys have any idea what the return to battery issue is caused by? Is there a "break in" period. Any suggestions would be appreciated.

How well did you clean it before you shot the gun? I have seen some P365's so coated in grease that we use half can of brake cleaner just to get all the crud out this included the striker channel and recoil spring assembly.
That said, It is my belief that any well fit gun needs a couple of hundred rounds fired to smooth things out. If I were you I would run a couple boxes of 147 grain ammo following a complete de-greasing and re-lubing before calling Sig.

 

[ClemY]

What it sounds like it could be is a slightly tight barrel. What it may require is stoning appropriate surfaces to finish fitting the barrel. If you don't feel comfortable doing that, return it to the factory and let them handle it.
