Used factory original Smith & Wesson hammer block for the L Frame Model 386 8-shot revolver chambered in .357 Magnum, new style configuration. The hammer block is a safety component that prevents the firing pin from contacting the primer unless the trigger is fully depressed — a damaged or missing hammer block is a critical safety deficiency that must be corrected.
