I choose my ammo carefully, practice when possible. I know most SD shootings are over in 3 shots, most of the time just showing a weapon stops the trouble. If I feel the need for a speed strip it would be easier to carry my LC9s with 7-8 shots of 9mm. The LC9 is easier to shoot well and has more shots but my Airweights are lighter and easier to conceal. For indoor SD I use standard velocity 38spl. +P for CC
