Designed for Smith & Wesson N Frame Model 29-2 revolvers chambered in .44 Magnum. Thumb pieces typically interchange across N Frame models of the same era, though professional fitting may be required to ensure proper function and appearance.

Installation Notes:

Professional gunsmith installation recommended. While the thumb piece is externally accessible, proper installation requires disassembly of the cylinder latch mechanism and precise fitting to ensure smooth operation.

About the Thumb Piece:

The thumb piece is the external control that operates the cylinder latch on Smith & Wesson hand ejector revolvers. Pushing forward on the thumb piece releases the cylinder latch, allowing the cylinder to swing out to the left for loading, unloading, and inspection. This simple but essential component must operate smoothly and reliably for proper revolver function.

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 third engineering change, representing a specific era of production valued by collectors and shooters.
