Armed self defense works even if you're not good at it. In this case, a store owner is assaulted by two armed men. When they jump off of him to attack someone else in the store, the store owner pulls a small concealed handgun from his waistband. This video is exactly why you carry your gun fully loaded with a round in the chamber; you can see that when he draws his gun, he tries twice to chamber a round, and then the magazine falls to the ground. The video skips forward a few seconds, and he has reinserted the magazine and then sucessfully chambers a round and starts firing. He doesn't even attempt to use his sights, but the bad guys don't notice; they're trying their hardest to flee!
