Are there any of these german made sa 22 cowboy pistols worth anything? They seem to be trouble free and easy to get parts for. There seems to be a list of brand names that are all similar. Some look pretty good with nickel plating and pearl handles. Others have long barrels like a buntline replica. Many have two cylinders with 22 lr and 22 mag. I have several that have fired many rounds and have killed lots of cans. Pawn shop prices always seem to be from $100 to $200. So, what does a person need to look for to get a good value in a single action 22?
