I got a P365 at the beginning of February and took it to the range. 50 rounds of Federal FMJ and 50 rounds of Winchester NATO and with each mag it would fail to return to battery at least 2 and as many as 5 times. I called Sig and they wanted the gun back so I sent it to them and I still don't have it back nor have I heard from them. After almost 8 weeks I would have thought Sig could have figured out what was wrong and gotten it back to me. Not impressed, I'll stick with my G43.
