The 642-2 Airweight Centennial design keeps the profile clean with its fully concealed hammer and double-action-only operation. This one is configured with fixed sights, including an integral front sight blade and a fixed rear notch in the top strap.

This revolver is clearly marked with "SMITH & WESSON" and ".38 S&W SPL +P" on the barrel, and "Airweight" plus "SPFLD, MA / S&W U.S.A." on the frame. The yoke/crane area is marked "642-2," and additional markings include serial "DJS" and a small numeric marking "707" visible on the frame/yoke area.

Combined with the 1.875-inch barrel and 5-round capacity, this is a straightforward example of the Model 642-2 configuration with no internal lock observed.
