Identifying Your Model Number

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

Compatibility Note

This is a centerfire K Frame barrel specific to the Model 64-3. Not compatible with rimfire K Frame models (17, 18, 48, 617, 648) or pinned-barrel variants.
