Suspect the spring is not installed correctly or damaged.
@lwt16
I'm leaning towards the latter and ordering some sear and trigger return springs. I would have statistically got it installed correctly due to how many times I stripped the FCU this weekend.
I'll update the thread after they come in.
Really hoping you get to the bottom of this. I appreciate you and @lwt16 posts, especially the photographs back and forth on this problem.
I am unlikely to become a P365 armorer, but this thread is like auditing a free class.
@lwt16 thank you for all the information here
If this were me, it would be on its way to Sig to fix or replace lol.
Thanks to the OP and @lwt16 for this thread. I was thinking about a P365 as a possible replacement for a j-frame, but it looks too complicated for a chimp like me. I did pass the info on to a friend who owns one.

Beware of my temper, and the dog that I've found...
No problem.
My 365 has been dead reliable and I figure I’m over 500 rounds of various brands of ammo. Definitely shoots tight at 25 yards and I’ve dabbled at the 50 y line with it.
Like most things if one keeps it clean and doesn’t mess with it they run problem free. Great ankle piece for work.

The P365 really is not complicated. It's not Glock easy, but it is significantly easier than a S&W wheelgun. The biggest takeaway is to build your spare parts kit for your EDC since springs do break and disappear into black holes when falling off the workbench.
That said, a 43x MOS did follow me home for Valentine's, so I got that going for me which is nice.
The P365x is now working correctly. Got my springs in today and a new sear spring put everything in working order.![]()
I already tossed it, but I did notice the short end of the sear spring leg was very sharp. I'm assuming I tweaked that end with the 1/16" punch lifting it to clear the Glock tool on the initial reinstall since it would never catch the safety pin properly. I also found that a 90 degree pick worked much easier in lifting the sear spring leg instead of the 1/16" punch.
I appreciate all that help in troubleshooting.![]()
