I believe that an investgation already showed that the discharge was caused by using the incorrect holster with the gun. You really should use a holster designed for the gun you carry. Duh!
I have been shooting for 45 years and have seen only one accidental discharge, I've seen quite a few negligent discharges, but just the one accidental discharge. It was a slam fire from a third-generation Glock 17. Lucky the guy was pointing the gun in a safe direction.
Yea it seems like it was user error from what I've been reading. I'm not gonna be giving up on my 320 any time soon, especially since I just bought an icarus grip mod, agency arms barrel and Jagerworks slide... lots of money I'll never get back surely haha
