Smith & Wesson Model 625 Performance Center Mountain Gun Cylinder Stop & Spring – Part# 62581
This is a genuine factory Smith & Wesson cylinder stop and spring 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 restoring proper cylinder lockup on your Model 625 PC Mountain Gun.
The cylinder stop (also called the cylinder bolt) rises to lock the cylinder in precise alignment with the barrel at the moment of firing. A worn, chipped, or broken cylinder stop results in poor lockup, cylinder wobble, and degraded accuracy or reliability. Includes the cylinder stop spring.

Installation
Cylinder stop replacement requires side plate removal and disassembly of the lock work. Cylinder timing must be verified after installation to ensure safe, reliable lockup. We recommend installation by a qualified gunsmith.
