My buddy was asking me about the P365 (he knows I frequent forums). After talking with him, a thought occurred to me, and wondering if anyone knows:

Did the barrel peening issue predate the broken strikers, or were they pretty coincidental?

It seemed to me the peening came first, which made me wonder if the fix to that led to slightly early unlock, which led to broken striker tips. But I honestly don't know the timeline.

You're correct, the peening came first.

I don't have any clue as to how, if in any way, it might have affected the timing.
