World's Tiniest Gun Scares Control Junkies
I doubt if that tiny Swiss mini-gun will ever become popular; it's so VERY tiny that it can't use conventional ammunition -- or, for that matter, any sort of really effective ammunition -- and it's hard for normal-sized human fingers to control. A far better choice is the North American Arms .22 mini-revolver, which fires standard .22 ammo and can (barely) be controlled by normal-size fingers.
