I have no idea, it is just what he told me... Does anyone know of a gun that has accidentally discharged because it didn't have the two safety mechanisms that are on the 1911?What on Earth was that guy talking about??? No caliber is more likely to "go off" than any other. That's entirely a question of the design of the gun, the firing mechanism and the safeties. There are 9mms to be had with the exact same configuration than a 1911 (which I suspect is where this guy was driving at with his nonsense). There's a lot of debate on manual safeties in general but again that's not a question of caliber.
