Need Help Identifying Your Model?

Swing out the cylinder and check behind the yoke on the frame for a model number. Model numbers began in 1957-58. If there is no model number, your revolver is from the Pre-Model era (pre-1957). Contact us with your serial number and we can help identify the correct parts.
