I was at the range the other day, practicing defensive shooting. I was working on engaging a threat from contact distance: protect my head and neck with my weak arm, draw and fire from retention with my strong arm.
I had run through the drill several times, and on the fourth draw my Glock 19 went 'click' when I pulled the trigger. It was so unexpected that I stood frozen for a second or two before my training kicked in and I quickly tap, rack, banged and completed the drill.
Afterwards, I wanted to know what happened so I searched the ground for the round that didn't fire. I couldn't find anything, so I am guessing that the gun didn't chamber a round. This could be because I was shooting from retention and not a normal firing grip. This may have cause me to limp wrist it, I don't know.
The biggest lesson learned was that I need to practice failure drills more often, as my initial response of standing there looking confused could have gotten me killed in a fight. Second lesson is that that Glock 19 is not as infalible as I had thought, but in all fairness it is probably from shooting it in an awkward position
