Worlds smallest gun is the Dyson LePetit Protector Ring Pistol.
It has got three levers,The largest one towards the top is the hammer, the one on the side and in the middle (in this photo) is used to release/spin the chambers. The smallest lever is the trigger.
the kick of the on this little package of concealed protection would not be anything to fret about. If anything, when fired, it might feel like flicking yourself on the finger. Each ring gun comes with a tiny flat head screw driver and sometimes you’ll see other tools which are used in ejecting the empty cartridges. If you look really closely at the rounds, you’ll see a little pin near the primer end of the round. That pin is probably the only thing preventing the rounds from falling out the front side of the chamber.
Theres no evidence of these still being manufactured today and it is assumed that a few of the guns rings(now Worlds smallest gun) are over 100 years old. The quality of workmanship is amazing with designs to make the gun appear like a nice fat ring that, if used with a right hook, could render a grown man unconscious!
The Worlds smallest gun doesn’t classify as the most efficient killing device but considering when it was made and the craftsmanship it took to make, it certainly is an exceptional one off antique firearm. Hat’s off to the unknown creator.
It is a Great collectors item, but if someone want to shoot it often, they’ll probably have to get their rounds custom made.
