Would I trust a P320? Maybe? They got a lot of attention, plus the DoD contract/scrutiny, so I think they probably got the engineering right eventually.
I guess I'm wondering why I'd give it a second look when there are so many other options out there.
I have a P320 FS, but I don't shoot it very much. My VP9, PPQ, and 2011s are more fun to shoot, handle better, and haven't given me reason to question them. Or make me feel like I'm a beta tester who paid for the "privilege".
