Just FWIW, the major drawback of the old Chicago Palm Pistol was that the cartridges had to be loaded from the center (hub) of a wheel-spoke type cylinder. That meant the cartridge had to be very short. In fact the .32 Protector (.32 Extra Short) was developed specifically for that pistol. It had a charge of four (!) grains of black powder. Possibly lethal, especially in a day when infection was usually fatal, but hardly a man-stopper unless the bullet hit a sensitive and vital spot, like the eyeball.
