After 2000 rounds, my P365XL has a lot of OOB failures

[Macchina]

I’ve been shooting this gun for 2 years. About 2000 rounds through it. Been doing an informal class with drills lately and at the last one I had about 10 RTB failures. It was a mess. Never had this before. I cleaned it well before and after the issue.
Here’s the weird things:

If I rack it slowly with or without a round it will stall at 1/4” OOB.
With the slide stuck OOB I can wiggle the barrel so it’s not the barrel.
Light pressure on the rear of the slide knocks it into battery.
It can’t be the extractor spring issue that people talk about because it binds with an empty chamber.

Any ideas?

I'd replace the RSA with a fresh one.

 

[trackskippy]

I agree, that would be my first thought.

What is the suggested replacement for them?

 

[Hartkopf]

Doesn't Sig have a short leash on their return springs for the 365s?

 

[Tinman357]

I'm not certain what the reccommended replacement interval for the RSA is. I remember thinking it was pretty short so I bought 10 for deep storage just in case.

I believe it was in the 1500 to 2000 round range. But don't quote me.

Sig Talk there is mention of cleaning the recoil spring assembly. Otherwise, some had mentioned changing them at 2,500-3K rounds per Sig's recommendation. Others have gone onto much higher round counts on the original. A YMMV scenario.

 

[trackskippy]

A quick search and it seems SIG recommends replacing the RSA at 2500 rounds.

I know the RSA test for Glock is to hold the muzzle up, pull the trigger, and hold it, then pull the slide back and ease it forward and when you feel the spring ease up, let go of the slide and it should go completely forward and close on its own. If it doesn't, or if it stops short, but goes if you lower the gun or release the trigger, you should replace the RSA.

Not sure if that applies to SIG, but you might see if youre running into that.

 

[Macchina]

I don’t think this is an RSA issue. I’ll replace it just in case but there’s a resistance there right before full battery that I never felt before. There is definitely an increase in drag when letting the slide down slowly.

 

[Hartkopf]

Here's a thread about a similar issue. Maybe.

Sig repaired my P365XL

I sent my Sig P365XL back to them for failing to return to battery. I received it back from repair in 8 days total. Can't get much better than that. The note in the box stated they replaced recoil spring, replaced extractor spring, lubed gun and fired 30 rounds Blazer Brass 124 gr. Noted no...

Hmmm...just passed 6500 rounds with my Glock 43X...no stoppages of any kind. Just sayin...

I remember hearing a Glock armorer instructor remind armorers that "fresh springs help keep guns alive".

Replacement RSA's, and non-captive recoil springs, are a relatively inexpensive way to help keep pistols functioning as designed. They're a wearable part, too.

RSA's have to help mitigate the potential influence of a number of things, like the vagaries of shooter grip stability, ammunition power (cycling and slide run velocity), fouling, lubrication, etc.

The Glocks I shoot every week get them changed out twice a year (roughly every 7500 rounds give or take). Last I heard, Glock lowered the count down to 5K, or do the test, which Ive yet to have a gun fail. Glocks RSA's are still pretty cheap, compared to others. Even the double spring Gen 4 and 5 RSA's arent all that bad.

I had an early Kimber Ultra Carry that had an RSA with a stupid replacement interval, and they were salty to boot. That gun never ran right anyway, but it was always just a tad better when the springs were new.

My Gun Broker-bought Ultra Carry II 9mm got a fresh RSA when I brought it home. So far so good.

Always a good idea to have a spare set of springs for guns, nothing is worse than heading off for a fun weekend of shooting and having one crap out the first day there. (Done that dance!)

OP let us know if that is the fix for your SIG’s issue.

Stay safe.

The RSA replacement is easy enough to try, but that extractor doesn't look right to me. I'll have to go look at mine now.

Just a reminder: it’s an empty chamber…

 

[Macchina]

Holy crap!!! I figured it out!

I took apart my striker tonight and that didn’t fix it, but while checking everything out I found a lot of wear on the slide where it enters the frame at the front… I had tightened my Streamlight down decently tight last time I cleaned it before I shot it last time. The front of the frame was definitely squeezing the slide, I could see it relaxing as I loosened the light and there are definitely new wear marks there.

I loosened the light and presto: it functions perfectly. LOL. Darn…

 

[Old Dog]

Thanks for letting us know! I was gonna lose sleep tonight worrying about my 365s.

Just kidding, but I wish I had $100 for every time I had a problem firearm, obsessed about it for too long, and then found out that I had actually caused the malfunction(s) or it was some routine maintenance issue I'd ignored...

Good work. (You did order a replacement RSA to have on hand, though, right?)

 

[Peakbagger46]

Excellent news and thanks for the update! I carry my XL off duty and you had me a little worried. Glad to know a striker fired Sig doesn’t identify as a Kahr after 2k rounds

 

[JDeere]

That was easy enough. Did you put a cheater bar on the wrench when you was tightening the light? Just messing with you. I have close to that many rounds through my 365 and was like uh oh.
