Compatibility

This hammer block is designed for the Smith & Wesson K Frame Model 65 revolver chambered in .357 Magnum. The hammer block is a critical internal safety component that prevents the hammer from contacting the firing pin unless the trigger is fully depressed. Because .357 Magnum and .38 Special K Frame revolvers share the same frame and most internal parts, this part may also be compatible with other K Frame centerfire models. Verify old style vs. new style configuration before ordering. This part is not compatible with rimfire K Frame models (17, 18, 48, 617, 648, K22).

Finding Your Model Number

Swing out the cylinder and check behind the yoke on the frame for the model number. Model numbers began in 1957–58. If your revolver has no model number, contact us with your serial number and we can help identify the correct part.

Installation

Disassembly and reassembly of the revolver is required to replace this part. Installation by a qualified gunsmith is strongly recommended. Factory replacement parts are manufactured to the exact same specifications, tolerances, and materials as the original.
