I bought an early P365 which has been flawless. Guess I got lucky. I replaced the striker just to be safe since I pocket carry it frequently. Last week I decided to get the big brother. I didn't dry fire it in the store or check the reset on it. When checking the reset and holding the trigger back it is VERY difficult to cycle the slide. I hoped this would get easier after firing. I've put just over 100 rounds through it and have had many issues with returning to battery. A quick tap and its back, but it happens almost every 5 rounds. I've never had an issue with limp wristing before so I don't think that's the issue. This was all with 115 grn ammo. I did shoot a couple of mags of carry ammo without issue. The cycling of the slide with the trigger back is easier, but still has more resistance than there should be. I'll give Sig CS a call on Tuesday. I hope just more shooting will be the fix, but it's disheartening to have an issue with a new gun. I've seen this reported on YOUtube, and I guess I should have been more thorough when buying. Lulled to complacency by my luck with the little guy!

Did you replace the striker with a factory part, or the LSI striker?

How much grease have you got on that XL?

"Limp wristing" has nothing to do with it. Lubrication, and shoot it more.

I already have a flawless performing early P365, but was looking at a new P365 at the gun shop this week (born July 23, 2019). The gun definitely had a place on the right side where the slide met resistance and didn't smoothly return to battery. It had just been delivered from the distributor and had no lube.

I wonder if the new P365xl has the same issue, if it will eventually smooth out or needs lube as suggested above. Hopefully it's something simple.

Lubed up before I ever took it to the range. I put the LSI striker in my original 365.

Same issue here...

I tried one today at my LGS. It was the lousiest excuse for a SIG I ever saw. Trigger was long, uneven, gravelly, and the break was more of a moosh-thru. The slide did not ride evenly on the frame. I really wanted to like it, but I guess I'll stick with my G48.

Interesting. I've been considering the LSI striker in my P365, though there have been no issues with it to date.

I looked at one and went with the Glock 48 in black with fact night sights .

Folk with the XL had better experiences using heavier bullet weight during fhe first 100-200 hundred rounds.

I bought my 365XL just after they hit the shelves.
The store mgr gave me 100 rounds of the SIG 147 ammo to go with it and that is what I used to get it started. I may have put a few drops of oil on the rails before I shot it but I don't remember.

For me the trigger and shooting was much smoother than my other 365 non XL but both shoot very well and haven't miss a lick in 500 rounds.

I don't know if the trick is to use the heavier 124 or 147 grain ammo first to get the gun to settle in but that is what I always do for any 9mm pistol I buy.

I'm guessing the lockup point between the barrel hood and the slide has a sharp edge or burr, and when the trigger is held to the rear it puts a little extra pressure on something that makes it hard for the barrel to drop out of lock.

His second video has flawless function and the issue working out rather quickly.

He also glossed over any kind of technical analysis other than "I see some wear here... hmm". Informative videos, but good god man if you don't know what you're doing don't try to diagnose issues.

I put another flawless 25 rounds of carry ammo through the gun. Followed that with 50 rounds of the ammo it didn’t like yesterday. No issues today with returning to battery. Still feel a bit of a catch when cycling the slide with the Trigger depressed, but much better than before. It looks like it just needs more aggressive ammo for a break in period. I’m still going to talk with Sig Tuesday and see what they say.

just a suggestion,clean and lube the pistol completely and then leave the slide locked back over night or even better for a couple days. works almost every time. if it dosnt your out nothing, then break in with hotter 124 grain ammo,

Spoke to Sig CS this morning. They said the disconnector was just breaking in and the gun will be fine. Just keep shooting it. No need to send it in. I'll keep shooting and hopefully all is well. It will be a while before I completely trust it!

During my first shooting, I fired 125 147 grain ammo. I had 25 failures to return to battery, the slide stop would not move unless hit with a hammer and the mags were unloadable past three cartridges. I would have sold the weapon at a huge discount then and there.
I cleaned the gun, lubed it and brought the uplula with me on the second session. I shoot 200 Aguila 124 grain ammo without a hitch. This gun needs a break in. By the second week of shooting the slide stop was finally loosening.

It is still a micro pistol, at its core. It is best to break it in, either by firing, or manually operating the slide back and forth with an empty gun and the trigger pulled to the rear for a couple hundred times.
