Yeah, i heard the P320 was originally a non-striker system that they modified to become a striker system to try and save research/development costs from creating a striker system from the ground up, which led to these wildly low tolerances in the FCU and ultimately a poorly designed firearm.

I’ve heard of no issues from the P365 models. A knowledgeable firearm instructor I talked to mentioned the P320 and P365 are entirely different designs internally, and the P365 holds up to Sigs (previously) positive reputation
