Smith & Wesson J Frame Model 30 Hammer Block - Used

$6.99

This listing is for a used Smith & Wesson J Frame Model 30 hammer block. Factory OEM part sold as-is.

The hammer block is a critical passive safety component in the J Frame revolver. It physically blocks the hammer from contacting the firing pin unless the trigger is fully depressed, preventing accidental discharge if the revolver is dropped or the hammer is struck. This used factory hammer block is correct for the Model 30 — S&W's classic .32 S&W Long Hand Ejector — and is an essential safety-critical part for gunsmiths performing action work or restoration on this vintage revolver.

Note: The Model 30 is chambered in .32 S&W Long, distinct from .38 Special. Hammer block fitment can vary between production eras and dash numbers. Always confirm your model and dash number before ordering. To find your model number, swing out the cylinder and check behind the yoke on the frame. Models without a number predate 1957–58 — contact us with your serial number for assistance.

Installation

The hammer block is a safety-critical component. Disassembly and reassembly by a qualified gunsmith is required. Verify correct function after installation before returning the firearm to service. Factory replacement parts are manufactured to the same specifications, tolerances, and materials as the originals.
