Finding Your Model Number

Swing out the cylinder and check behind the yoke on the frame. Model numbers were introduced in 1957–58. If your revolver has no model number, it may pre-date 1957 — contact us with your serial number and we can help identify the correct part.

Factory replacement parts are manufactured to the exact same specifications, tolerances, and materials as the originals.
