Historical Note

The Triple Lock, introduced in 1908, was Smith & Wesson's premium Hand Ejector revolver featuring a third locking point on the cylinder crane. These revolvers were manufactured from 1908 to approximately 1915 and are highly collectible. Genuine period parts are increasingly difficult to source.

Installation Note

Professional installation by a qualified gunsmith experienced with vintage S&W revolvers is strongly recommended. Fitting may be required to ensure proper mainspring tension, trigger pull, and reliable ignition after installation.
