When I carry a 1911, it is cocked and locked bullet in the chamber. Cannot imagine otherwise. When I carry a revolver, I don't have to worry about it. Drills are a good thing for FTF, FTE, and wounds; however, the best thing you can do is learn to put two bullets center of mass in a target 30 feet away as fast as possible. It gets easier the closer you get. When you get to a second or less from a concealed draw you are about as good as it will ever get. Hard to maintain without practice. Using quality carry ammo is essential.
