Revolver Firing Pin

This is the Apex Revolver Firing Pin, a drop-in replacement component designed to address light-strike issues in Smith & Wesson centerfire revolvers, particularly after trigger action work has been performed. The firing pin is paired with a reduced-power firing pin return spring (included) to increase primer impact energy. This combination reduces the probability of ignition failures in revolvers with reduced mainspring tension or high-performance trigger jobs, without compromising reliable primer reset. Intended for duty, carry, or competition use where ignition consistency is non-negotiable.

Platform Compatibility

• S&W J-Frame (all centerfire models: Model 36, 60, 340PD, 640, etc.)
• S&W K-Frame (Model 10, 13, 14, 15, 19, 66, etc.)
• S&W L-Frame (Model 586, 686, 619, 620, etc.)
• S&W N-Frame (Model 27, 28, 29, 57, 625, 627, etc.)
• S&W X-Frame (Model 460, 500)
• Does NOT fit S&W rimfire revolvers (Model 617, 63, etc.)

Key Features

• Extended firing pin length vs. factory S&W unit for deeper primer strike
• Reduced-power firing pin return spring (included) reduces drag on the hammer fall
• Designed to work with reduced mainspring weights (e.g., Apex spring kits or aftermarket springs)
• Drop-in installation – no frame modification or fitting required
• Materials: heat-treated tool steel, black oxide finish

Install Difficulty: 1/5

Tools needed: Small flathead screwdriver or pin punch, slave pin (optional). Remove cylinder, open sideplate, extract factory firing pin and spring, install new components. Time: less than 15 minutes for first-time install. Sideplate screw torque: 15 in-lbs. No permanent modifications.

FAQ

Will this firing pin work with my factory S&W mainspring?

Yes. The kit is designed to function with factory mainspring tension, though its primary benefit is realized when paired with a reduced-power mainspring. Expect a measurable reduction in light-strike probability compared to the factory pin under the same spring load.

Does this kit include the return spring?

Yes. The reduced-power firing pin return spring is included in the package. Do not substitute with factory spring – the reduced spring weight is calibrated to the pin geometry for reliable reset.

Is this compatible with MIM or forged factory firing pins?

This replaces both MIM and forged factory firing pins. The kit uses a machined tool steel pin that is interchangeable with all S&W centerfire revolver firing pins of the same frame size. If your revolver has a frame-mounted firing pin bushing, ensure it is clean and free of debris before installation.
