The worlds smallest revolver

So big things do come in small packages. At just 2.16-inches, the SwissMiniGun is the world’s smallest functional revolver, complete with ammunition — shoots tiny 0.35-inch long bullets.
This miniature Swiss-made revolver and its ammunition are painstakingly crafted using watchmaking technology. Looks like the little shooter could do some damage, propelling that tiny slug at 426.5 f/sec. out of the muzzle.
I’m no gun expert, but why would somebody want to carry this? It doesn’t seem like you could use it for defense, unless you are using it to hold a pack of rabid squirrels at bay.
