Yeah, the 365 has had a rash of broken firing pins that some are blaming on the striker drag you show. From what I could gather the firing pins are MIM manufactured. There have also been a lot of dead triggers caused by trigger spring failures. I think I'd wait this out if I were to buy a P365 which I'm not anyway; love my 9mm Shields.
At this point I'm probably going to kick my plans out another year. Don't really need one of these things, my G43 and G26 (and all of its other glock siblings) suit me just fine.
