It’s total length does not exceed 5.5 cm.At just over two inches long it is the world’s smallest gun – but the 300mph bullets it fires mean it is still deadly. The gun shoots 2.34 mm calibre rim fire ammunition especially developed for it as the smallest rim fire ammunition in the world. Source: SwissMiniGun
