Introducing: the .22 caliber Zippo gun
This gun is about as tiny as it gets. Gizmodo explains that the 4mm bullets are about the size of Tic Tac and wouldn’t carry much of a punch. We wouldn’t want to be on the receiving end of one of these, but at the same time you can’t be certain that this thing is going to deliver a kill shot.More
It’s a novelty item more than anything else, though it does have some serious self-defense potential. Could you imagine carrying one of these around in a state where concealed carry is banned? Cops wouldn’t even give it a second glance.
