Thank you for the welcome and that information! I am new to the forum and I have been collecting S&W revolvers for a few years now. It all started with a Mod. 31-1 32 Long I got at a flea market. All my S&W are pre 81 with pinned barrels. This K-22 has me in love with five screw models. Regardless of the services cylinder and possible mismatch grips, this Smith is a great piece of history. If only I could know its story.
