The perfect concealed carry piece, IMO, is the S&W 340PD, 5-shot.357mag DAO j-framed revolver. Small, incredibly lightweight at only 11.4oz and crazy potent.
It's unpleasent side is shooting it, but who cares when confronted with life or death. I can shoot it well enough, it just isn't fun.
It's become one of my favorite companions.
