I just started carrying a BUG, its a s&w 442. I keep it in my left front pocket which is my weak hand side. my thinking is if I need to go to my BUG it's probably because my strong hand/arm is for whatever reason out of the fight. I also would like to get either crimson trace grips or lasermax grips which are substantually cheaper.
My BUG is a Kahr CW9 in a Galco ankle holster. It's easily accessible with either hand. I have carried it in a pocket holster on occasion. I prefer a jacket pocket over pants only if I'm positive I won't be taking the jacket off. I would suggest practicing with each hand with both your primary and BUG.
