7 Ounce Mini-Gun Fires 4.5mm Bullets

The SwissMiniGun is the size of a key fob but fires tiny 270mph bullets powerful enough to kill at close range. Officially the world’s smallest working revolver, the gun is being marketed as a collector’s item and measures just 2.16 inches long (5.5cm). It can fire real 4.53 bullets up to a range of 367ft (112m). The stainless steel gun costs £3,000 although the manufacturers also produce extravagant, made-to-order versions made out of 18-carat gold with customised diamond studs which sell for up to £30,000.
