Originally cataloged in early 1952 as the Blanchard (red) ramp, later versions of the 1952 (centennial) catalog listed this sight as the S&W red ramp. This sight, with a white outline rear sight was standard on the 44 Magnum introduced in January 1956. Prior to that, the red ramp was installed on many of the 1950 44 Targets with a 4-inch barrel and was a factory option for the ".357" Magnum.
