I need info on a 22A. This is my first semi-auto. While the gun is in pristine condition, it came with no manuals or other papers. I got it from a friend who never shot it, but says she bought it "years ago". Here is the serial #UAU5XXX. When was it made? Also, how much does this pistol weigh? Any info would be appreciated. Anything else I should know about this gun? Please reply. All of my other guns are revolvers. Also who sells holsters and magazines for this gun?
