Function: The firing pin bushing retaining pin secures the firing pin bushing in place within the frame. Without this pin, the firing pin bushing can shift or fall out, causing firing pin misalignment and potential misfires or damage.

Installation: Professional gunsmith installation recommended. The firing pin bushing retaining pin requires disassembly of the hammer and firing pin assembly. Proper installation is critical for safe and reliable firing pin function.

How to Identify Your Smith & Wesson Model: Swing out the cylinder and check behind the yoke on the frame for the model number. Model numbers began in 1957-58. If you need assistance identifying your revolver or confirming compatibility, contact us with your serial number.
