Take a gun and apply expertise and technology from the Swiss watch industry, and you’re left with the world’s smallest revolver.
The Swiss Mini Gun has a total length of 5.5 cm, and uses 2.34 mm calibre rim fire ammunition. But don’t be so quick to label this tiny weapon as cute. The miniature gun is a double action revolver with all of the same features found on a typical gun. In fact, it fires at just under 400 feet per second, making it potentially lethal.
Available in stainless steel or a solid gold version that can be customized (i.e. adding diamonds). But don’t get too excited if you’re a collector in the U.S. – the gun doesn’t meet the minimum size prerequisites, and is not importable.
