Another thing kinda off topic but in my concealed carry class this morning I was told by the instructor that semi autos on avg fail every 7 rounds but didn't get much further into it..if that's true I'm assuming it's not taking user error into consideration as well as gun brand. He said a cop he knew that was involved in a shoot out carried 13 rounds and his gun malfunctioned twice during the incident. Now I found this to be very unsettling and almost considered a revolver but I'm skeptical on that because there are so many possible variables. I have fired about 10k rounds thru my glocks and the only malfunctions were ammo and two limp wrists when I first bought my g21..any thoughts on that also?jakedrennan45 said:
