Wonder if that guy's P320 was one of the ones up for the "voluntary upgrade", the guy knew about the "recall", and decided not to do it? But discharge when removing from holster sure sounds like a trigger pull...
Safety "improvements" for certain models already sold to consumers are nothing new... my stepson has a couple Thompson/Center rifles that were affected by safety issues as well and got sent back for "voluntary upgrades", and that wouldn't stop me from buying a T/C. There's so many things that can be said here, but I'll just leave it at this: some people shouldn't own guns.
