Smith & Wesson N Frame Cylinder Stop & Spring – Old Style
This factory original Smith & Wesson N Frame Cylinder Stop & Spring is a critical timing component that locks the cylinder in alignment with the barrel at the moment of firing. The cylinder stop (also called the cylinder bolt) rises from the frame to engage the cylinder notches, preventing rotation during the firing cycle. A worn or broken cylinder stop causes cylinder timing failures and dangerous misalignment — making this an essential replacement for any N Frame restoration or repair.

Installation Note
Cylinder stop replacement requires side plate removal and timing verification. Professional gunsmith installation is strongly recommended. Improper installation can result in dangerous cylinder misalignment. Always verify cylinder lockup and timing after installation.
