How to Identify Your S&W Model
To determine your Smith & Wesson revolver model number, swing out the cylinder and check behind the yoke on the frame for the model number stamped into the metal. Model numbers began in 1957-58. If no model number is present, your revolver may be pre-1957. Contact us with your serial number for assistance in identifying the correct parts.
