look AROUND a bit, see LOTS of guys with

one or both hands in pants pockets. Nobody pays any attention to them at all. However, if they ARE getting ready to pull a gun, and you have a fastened coat or a shirt over your belt rig, you have no chance at all of beating them to the first shot, , if they truly intend to fire the instant that they can clear their pockets. I don't care who you are the belt rig and your reaction time aren't NEARLY fast enough.
