Made in Switzerland (of course!), by SwissMiniGun company. On their site you can see illustrations of this revolver in real size: no bigger than 5.5 cm (2.16 inches). Even though you can put this gun on your key-chain, it’s a deadly weapon. It fires 2.34mm bullets, with the killing range of 112 meters.
SwissMiniGun can also be more expensive than a luxury Swiss watch. In fact, one of the offered models is made in hand-engraved 18k gold, encrusted with the choicest diamonds (price starts at $50,000) -
