Great responses guys! I think one thing that makes carrying larger guns more feasible is some of the holster designs that are available these days. As a part of my job, I often have to fly while armed. A local holster company makes great IWB holsters. With his stuff, I can hide a full size gun, extra magazine, and handcuffs under a polo shirt and no one ever notices.

I definitely need to do more shooting while moving with a sense of purpose. At work, we never go faster than L&I avoidance speed. A couple detectives got me into shooting IDPA and it helps a little, but sometimes the game of IDPA overshadows tactics. Since I’m not gonna win, I often will shoot a match in a more tactically sound fashion and not worry about a few proceedurals.
