About 30 years ago I ran into a guy selling a Ruger semi auto 22, and I had always wanted one so I bought it. When I got it home I got into my safe and began pawing through guns trying to find a space for the new pistol, and found two, not one but two, other Ruger .22 semi autos that I already owned. I had no recollection of when or where I had bought them, and to this day I don't. Sometimes opening the safe is better than Christmas morning!
