Sig 365 owners question on striker return

[Saltwater60]

I recently purchased a 365 and 365xl and I got some wonky primer strikes. I did some research and it seems fairly normal since the firing pin is on an angle. While shooting I had a few failure to fires due to light primer strikes so that lead me to take apart the striker and clean the channel with some solvent and acetone. The striker had a bunch of brown crusty grease on it and so did the channel. Both are now clean with a very fine coat of oil on the striker assembly. I wetted my finger and wiped it on the assembly.
I put it back together and when I dry fire the gun the striker doesn’t return back into the channel all the way and protrudes a bit into the chamber. The 365 does the same and doesn’t return so I can’t imagine both having issues. I read that the old strikers had some issues and the new design fixes this. I just bought my guns new so I can’t imagine this is it, but just wondering if you guys have the same occurring in your guns or not. Do you see this as an issue?

Yeah didn’t seem right to me. Thanks. It is both of them for sure and seemed odd both of them would be off like that.

I could be wrong, but I thought you were not supposed to lubricate the striker assembly/channel?

Recently put 400 rounds (over the course of two outings) through my new P365X and didn't have a single failure to feed nor failure to eject, and went bang every time. If I'm not mistaken (as mentioned) early models had an issue and I think you can check your serial numbers against a list, which I don't have handy.

You’re correct on this. I investigated this after shooting my forearms and the primers looked dimpled and a bit of drag on them. I learned that the earlier stickers had issues and due to customer complaints and concerns the striker design was changed. I have the new updated striker design that they are selling today and my forearms were made in 6/21 and 12/21. To my understanding those dates are past when the issue occurred and the striker return spring should make it return from the striker hole in the slide. Mine does it dry and after I put a bit of oil on it.

It seems the early striker issue was tip breakage, so ignore my comment regarding serial numbers. With that said, I did come across this article containing the following quote from Sig's production manager:

Q: What is “primer drag” and does it cause striker breakages?
A: No. “Primer drag” is found on fired cases and is simply a drag mark slightly below the indent in the primer. It is caused by the pistol barrel unlocking while the striker is returning back to its recessed position. This is not uncommon, and happens in most striker-fired micro compact pistols due to the increased slide speed. The protrusion of the striker tip during ignition is minimal and has no effect on the striker’s durability.

Reports of SIG P365 Striker Issues: Real or Rumor? -

While this may be news to some of you, SIG enthusiasts have noticed some recent buzz about perceived firing pin issues with the SIG P365 on social media. The P365 is, of course, SIG’s newest subcompact that crams 10+1 rounds of 9mm into a chassis the size of a single stack pistol – and with …...

So I just investigated a bit further and it seems there is zero spring return in my striker assembly at all. I just took apart my 365 and when I push the button in the slide assembly that allows the striker to move forward it does move forward without the trigger burnt depressed and even with this button still push down the striker does not retract back into the slide assembly from the chamber area. That seems odd to me, but maybe I never caught this on other pistols.

I just spoke to a sig representative over the telephone and the wait time was non-existent. He listened to my concerns and we talked a little bit back and forth on what was occurring. He did offer to have the guns returned so I just asked directly is it normal that the firing pin isn’t returning into the slide on its own when I push the detent? He said yes because firing the gun and the slides rearward montion will cause it to return and not spring tension as I read on the internet. I then asked if that’s why the primers looked funny and dimpled out around the firing pin with the drag marks on the casing and he kind of said yes without admitting it. I think they are afraid of the primer drag reputation still. We settled on me shooting the guns again and he did say I should not have to remove the striker assembly since they consider that armors level of disassembly. It’s easy to do and many have said this is what has solved their light primer strikes and my 365xl had some thick grease that was brown in that channel and on the pin. The spring for the striker assembly was sticky as well. I don’t really want to return the guns and he was very polite. I hope they shoot just fine next outing. Here is a picture of some of the cases. You can see in the second and third pictures how the primer almost dimples out around the firing pin hit. I just thought it was weird.

This thread backs up what I was told today by the sig rep and is about the time of my guns being produced. I’m confident now and I didn’t have any light strikes, but my shooting partner did. I said try gripping the gun a bit tighter and they stopped so maybe limp wristIng was the problem all along. I also figured maybe shooting had pushed some lube out as well. Thinking about it my shooting partners shot placement improved after saying grip tighter so that leads me to believe it was limp grip.

Striker reset spring on new 365x models

FYI--TL;DR AT THE BOTTOM --- Got a call from my FFL last week that my 365X was ready for pickup. Loaded up the 2 newest AR pistol builds, my shield, and other 365 and put lots of lead down range finally. Grabbed the mail on my way home and received my package from Shooter Lube-perfect timing...

I have both a P365 and a P365XL. By no means do I have a lot of rounds through them but I never had this problem. I also never took apart the striker. I basically just stick to field stripping and cleaning my handguns.

So do you k ow when yours was made? It seems about may or June of 2021 they got rid of the striker return spring. I think it’s an odd move, but what do I know.
How do your primer strikes look? Similar to mine or way different.
