The bolt assembly is a critical timing component that must be properly installed and adjusted to ensure the cylinder locks up correctly at the moment of firing. Proper installation requires complete disassembly of the revolver's action and precise fitting to ensure correct timing, engagement, and cylinder gap. Only a qualified gunsmith should install this component.

About the Bolt Assembly:

The bolt (also called the cylinder stop) is one of the most important timing components in a revolver. It pops up through the frame to engage notches in the cylinder, locking it in perfect alignment with the barrel at the moment of firing. The spring provides the force to raise the bolt, while the plunger helps control its movement. Proper bolt function is essential for accuracy, safety, and preventing cylinder endshake.

About the Model 29:

The Smith & Wesson Model 29, introduced in 1955, is one of the most iconic revolvers ever produced. Built on the robust N Frame platform to handle the powerful .44 Magnum cartridge, it gained worldwide fame through Clint Eastwood's "Dirty Harry" films. The dash number (-2) indicates the second engineering change, representing a specific era of production highly valued by collectors and shooters.
