This tiny, tiny gun can kill you. Believe it or not. The SwissMiniGun is about 2 inches long (approximately the size of a key chain) but fires tiny 270mph bullets powerful enough to kill at very close range. The stainless steel gun costs $6,000 although the manufacturers also produce extravagant, made-to-order blinged out versions made out of 18-carat gold with customized diamond studs which sell for up to $60,000 for those who like to shoot or get shot in style. The gun is the first product of the SwissMiniGun company, a gunsmith company based at La Chaux-de-Fonds, Switzerland.
