Oh, and I forgot about the best smallest handgun I own. North American Arms .22 LR revolver. That gun is so small you can carry it in your pocket, sock or even in a empty cigarette pack! It's five shot and I load it with CCI Stingers. It is also stainless so you don't have to worry about it! You have to be fairly close for it to be effective though! But five shots of CCI Stingers would do anyone any good!
