The SwissMiniGun is officially the smallest gun in the world. Look at the picture on the right and it appears to be just a regular revolver, apart from the “oversized” trigger sticking out the bottom. One glance at the picture on the left, though, shows that it could easily be used as a key fob.

But don’t go hooking this up to your keys, at least not while it’s loaded: Somebody is bound to grab it and squeeze the trigger. If that happens, you’ll be picking 2.34mm caliber bullets out of your body for weeks.

The tiny gun is, of course, made in Switzerland and measures just 5.5cm (2.2 inches) long. The bullets, which are rim firing, are so small that they really won’t do too much damage. In fact, the makers want to be very clear about this:

We would like to take this opportunity to inform journalists who are interested in writing articles about our product that the power of most airguns or BB guns, which are in many countries freely on sale, can exceed over 10 times the power of our ammunition. We do not wish to find on the web the same kind of nonsense article we have found lately.

Still, it would certainly sting, and could probably take your eye out. The gun costs a rather hefty 6,500 Swiss Francs, or just shy of $6,000. There is also a gold edition which can go for up to $50,000, but you’ll have to travel to Switzerland to buy one: While it is exported to some markets, the gun is actually too small for the US, and “does not meet with the minimum size prerequisites”.
