i may be totally bs-ing you all right now, but i vaguely remember hearing from a guy who's second cousin knew the ups driver that delivered qvc stuff to the builder's wife (not really, my buddy owns a left-handed caspian) and the twist supposedly torques the pistol into your palm, having it the other way would torque it towards your fingers, and be less controllable. i have no sources, and cant check my work, but that is something i remember hearing.
