There's just so many variables for why a gun malfs. In all the various matches and training sessions I've been at it usually seems that it's ammo, mag or maintenance related. Sometimes, a combo of all three. When I switched back to the 1911 after years of the Glock format, I suffered thru some degree of snafus before I got all the factors in tune. Mags and ammo where the main points. I always take a "back up" gun, just in case something "serious" breaks. This is also why I have two identical guns: one that I shoot the heck out of and one that I carry. Like others have pointed out, stuff breaks, especially when you play alot or play hard. Stay safe.
