How to Identify Your Model

Swing out the cylinder and check the frame behind the yoke for a model number. Model numbers began in 1957–58; if there's no model number, your revolver may predate that, and we can often still match the part using the serial number — just reach out.

Gunsmith Required: Disassembly and assembly required to replace this part. Some parts may require installation and fitting by a qualified gunsmith.
