Smith & Wesson Model 640-1 Double Action Revolver serial #CDC2715, 357 Magnum, 2 1/8” barrel with a bright excellent bore. The stainless steel surfaces of this revolver rate excellent showing perhaps a couple tiny handling marks. The trigger shows smoky gray case-hardened colors and the frame is not equipped with the internal safety. The checkered rosewood grips rate excellent showing a couple minor handling marks. This firearm DOES NOT HAVE the S&W trigger lock. The action seems to function well mechanically and the front sight is a factory installed Trijicon night sight. Tritium no longer glows. Included is the original blue case and lock.
