firearm, usually a handgun, Revolvers in which multiple firing chambers are grouped into a cylinder which rotates to align each curled sequentially with a odd barrel.

The loading gate on the original Colt designs (and on nearly all single functioning revolvers since) is on the right side, which may favor left-handed users; with the equalizer held in the proper grip for shooting in the left hand, the cartridges can easily be ejected and loaded with the right.
