It is only moved out of the way when the trigger is fully depressed, preventing the hammer from reaching the firing pin if the revolver is dropped or the hammer is struck accidentally. A missing, worn, or improperly fitted hammer block creates an unsafe condition and must be replaced immediately.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstallation Note\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eProfessional gunsmith installation required. Hammer block replacement involves sideplate removal and action reassembly. Proper function and drop-safety must be verified after installation.
