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

The P365 does have essentially one point of failure on the striker assembly (see here https://www.reddit.com/r/SigSauer/comments/c5ddz5/can_someon...), and lacks a trigger blade safety.
