Smith & Wesson Model 625 Performance Center Mountain Gun Hammer Block – Part# 62581
This is a genuine factory Smith & Wesson hammer block for the N Frame Model 625 Performance Center Mountain Gun chambered in .45 ACP. A used new-style part in serviceable condition. The hammer block is a critical passive safety component — it prevents the hammer from contacting the firing pin unless the trigger is fully depressed, protecting against accidental discharge from drops or impacts.
If your revolver has a worn, cracked, or missing hammer block, replace it immediately before returning the firearm to service.

Installation
Hammer block replacement requires full disassembly of the lock work. As a critical safety component, we strongly recommend installation by a qualified gunsmith. Do not return the firearm to service without verifying correct function after installation.
