Ring Revolver

Also Known as the Protector Ring this particular gun just happens to be the smallest opperational revolver in the world. But because of it's small size some say that the burn from gunpowder would cause more damage than the bullet itself.
Although not much is known about the pistol it is said to be mostly sold to gamblers for a incognitve form of protection and was designed in the late 1800's to early 1900's
