All these guns are much smaller than the smallest gun I have and contemplate ever getting, but…
The teeny weeny guns. Denise likes them and calls them Vest Pocket guns and Mouse Guns.
Small bullets, short barrels, means inaccurate and less deadly. These really are only an option if the alternative is having noting but your teeth to fight with. Unless you cram a full size round in there. Like a .44 Magnum!!!!
The point is to be armed in a situation where a Colt Commander or Glock 22 is just too bulky to have. I wouldn’t want to lug around .45 in t-shirt, shorts, and barefeet weather. Florida in the summer time.
The Kel-Tec .380 is wallet sized. And there is a wallet shaped holster you can buy after-market. And you can shoot with the pistol in the holster on some of them. Probably enough to drive a New York City cop crazy, as they routinely shoot you when you pull a regular wallet.
The Beretta Tomcat is about the same size as the Kel-Tec, but probably better made, if slightly bulkier and less ‘squared’ off. A bit more expensive too. And it’s a slightly smaller cartridge than the above, at .32, and they have options in the same sort of rig for a .25 or .22, too.
And for the ultimate small gun, the true Derringer. Classic styling and design Similar to the design you’d expect Doc Holiday to have playing card in Tombstone Arizona. Can you shoot .44 magnum out of these 2-shot classics? Ouch. Reports of shooting the .357 out of a light-alloy snub-nose revolver tell of discomfort. I can’t imagine the horror of shooting .44 mag out of this. Though they have a certain amount of HEFT. These things look and feel solid in the hand. At least. Nice piece of machining work. The ones I’ve seen. But murder on the hands in any sizeable caliber.
Ok, ok, they don't have a .44 Magnum in their catalog. I made that up. The biggest they have is the classic .45 Colt. A lot less powder charge in that cartridge. But that is a whole lot of bullet for a small gun, too.
Naw. If I am forced to go the mini gun route, to shrink beyond the pocket gun to the VEST pocket gun, a gun the size of a pocket watch, I’d probably go for that revolver from North American Arms, and in .22 magnum. The nifty thing with these is that they can come with a pocket clip, making them look like a pocket knife hanging on the inside of your pants pocket. Kim du Toit recommended the caliber. A little extra oomph and you can get the shot shell in that size. But is this mouse gun, or any of the other lesser contenders on my MASTER list? No, not yet.
