How to Identify Your Smith & Wesson Model Number
Swing out the cylinder and check behind the yoke on the frame for a stamped model number. Model numbers began in 1957–58. If there is no model number, your revolver may pre-date 1957. In that case, contact us with your serial number and we can help identify the correct part.
