Important compatibility notes:
- This is a centerfire hammer. It is not compatible with rimfire K Frame models (17, 18, 48, 617, 648) which require a different firing pin configuration.
- Case colored finish is found on earlier production revolvers. Verify your revolver’s production era and dash number before ordering.
- Not for stainless (Model 64, 65, 66, 67) or nickel-plated revolvers.
Function
The hammer is cocked either manually (single-action) or by the trigger pull (double-action). When released, it drives the frame-mounted firing pin forward to strike the cartridge primer. A worn, chipped, or improperly fitted hammer can cause light primer strikes, misfires, or unsafe conditions.
Installation Note
Professional gunsmith installation required. Hammer fitting involves sear engagement geometry, hammer-nose protrusion, and timing verification. Do not attempt without proper tools and training.
