4/28/20 - This is a mint example of a Smith & Wesson Model 22-4 Revolver, chambered in .45 ACP. The barrel is 4.5". This model was Smith & Wesson's remake of the original military model 1917 used in WW2. From the serial number, we believe it was manufactured in the 2000's. This particular example is in mint condition. The only sign of wear is a very faint roll mark on the cylinder. The gun functions properly and everything is tight. The grips are excellent. The bore is minty - shiny with very strong rifling. FFL required.
