In all seriousness, P320 is one of the most popular firearms in USPSA for CO. Think about how many matches there are each year in America, from local level 1 to national. Maybe thousands? Think about how many P320 in each match, how many rounds fired in each match, how many times they go in and out of holster, among all the matches. Every year. Those are some extraordinarily large numbers.
You would think if these things do happen, even with a very small probability, they would happen in USPSA and other matches on a regular basis. Competitions are the ultimate testing bed for all firearms.
I think all shooters in competitions agree that guns simply don't fire by themselves. And if anything weird happens, which usually results in DQ, it is ALWAYS the user's fault.
