The hammer block is a critical internal safety component in Smith & Wesson J Frame revolvers. It prevents the hammer from contacting the firing pin unless the trigger is fully depressed, providing drop safety. A worn or damaged hammer block can compromise the revolver’s drop safety. This genuine OEM factory part has been inspected and is in good working condition.
Note: An alternate revision of this hammer block (part# 36120C) is also available in our store. Professional gunsmith installation required. This is a safety-critical component — proper installation and function testing are essential before returning the revolver to service.
