Function & Importance

The hammer fly is a small but critical component that transfers the hammer's striking force to the firing pin. When the hammer falls, it strikes the hammer fly, which in turn strikes the firing pin to ignite the primer. This part is essential for reliable ignition - a worn or damaged hammer fly can cause misfires, light primer strikes, or complete failure to fire. The hammer fly also helps protect the firing pin from excessive wear by absorbing some of the hammer's impact.

New Style vs. Old Style

Smith & Wesson produced different styles of hammer flies over the years. This is the "new style" design. The new style may have different dimensions or mounting methods compared to earlier versions. It's important to verify that this new style hammer fly is compatible with your specific revolver before ordering. If you're unsure which style your revolver requires, contact us with your model and serial number for assistance.

Installation Notes

Professional Installation Recommended: Disassembly and assembly required to replace this part. Some parts may require installation and fitting by a qualified gunsmith to ensure proper function and safety. The hammer fly must be properly positioned and secured to ensure reliable firing pin operation.

Identifying Your Smith & Wesson Model

To determine your revolver's model number, swing out the cylinder and check behind the yoke on the frame for a MODEL NUMBER. Model numbers began in 1957-58. If there is no model number, your revolver may be a pre-model (pre-1957) M&P or Victory Model. Contact us with your serial number if you need assistance identifying the correct parts for your revolver.
