Cute little pistol
I don't need a 45 caliber. If I shoot someone with a 22 that is going to take all the piss right out of them. Also easier to aim and shoot. But I don't plan to shoot anyone the only reason I might ever use it is to shoot a varmint harassing our chickens. The 22 caliber is more than enough.
Also not my only firearm I do have a semi auto rifle for the apocalypse chambered in 6.81 SPC and several high capacity magazines but if I grab the hatchet you should run
