The Model 640 Centennial uses an internal hammer and DAO operation, giving it the fully enclosed Centennial-frame profile. This example is a pre-lock configuration with no internal lock keyhole. The revolver is built entirely of stainless steel with a satin stainless finish on the frame and cylinder.
The 2-inch barrel has a heavy profile with an underlug, and the five-shot cylinder is fluted. The ejector rod features a knurled tip, and the underlug is short as noted by the factory. Fixed sights include a serrated ramp front and a topstrap groove rear.
Factory black rubber finger-groove grips provide a secure, hand-filling hold. The revolver retains Smith & Wesson's circular "TRADE MARK" logo and Springfield, Mass. rollmarks, alongside "MADE IN U.S.A. MARCAS REGISTRADAS" markings.
Factory product code 103796 is noted on the box label, matching the configuration described: Model 640 Centennial, .38 Special, stainless, 2-inch barrel, DAO. This U.S.-made example aligns with the Centennial series features and construction.
