Smith & Wesson Model 625 Performance Center Mountain Gun Safety Lock Parts – Part# 625C
This is a genuine factory Smith & Wesson safety lock parts set for the N Frame Model 625 Performance Center Mountain Gun chambered in .45 ACP. A used new-style part in serviceable condition — a cost-effective solution for replacing missing or damaged internal lock components on your Model 625 PC Mountain Gun.
The S&W internal safety lock (introduced circa 2001) is a key-operated mechanism built into the left side of the frame above the cylinder release. When engaged with the provided key, it locks the action to prevent firing. This parts set includes the internal lock components for the new-style (post-2001) configuration.

Note: The S&W internal safety lock was introduced on most models around 2001. Pre-2001 revolvers do not have this lock mechanism and these parts will not apply. Always confirm your revolver's production date before ordering. Model numbers are stamped on the frame behind the yoke when the cylinder is swung out. Contact us with your serial number if you need help confirming production date.
Installation
Safety lock component replacement requires side plate removal and careful disassembly of the lock mechanism. We recommend installation by a qualified gunsmith to ensure correct function and that the lock engages and disengages reliably.
