Ruger makes a .22 revolver that is fun. Im thinking my first .22 may be a lever action. .22 can kill just fine with good shot placement, or at least get someone off your back, but a lot of people shy away from using it for CCW because it's not the most reliable caliber.
If they made something like an all metal double stack 1911 mouse gun/vest gun .22 it would be amazing. Imagine if they had ultra thin wood or bone grips.
After getting a Seecamp .32 I'm taking a break. I may or may not get into cowboy action shooting, which would lead to me having to get a few single action guns.
