I'm a little confused here. Why would you get a small, easily concealable gun, then make it hard to conceal with a pair of big grips? I have medium-large hands and like a handful of grip with larger guns, but with the little I- and J-frame sizes I adjust to a two finger grip and let my pinky have the day off. In Bullseye we were taught to grip with the middle and ring finger and to leave the pinky soft anyway, so this works fine with small revolvers for me at least, but as with all things, YMMV!
