Manufactured between 1908 and 1915, the Triple Lock was one of the precursor weapons to Smith & Wesson's Magnum revolvers. Chambered for the then-monstrous 44 Special cartridge, S&W feared that the standard Hand Ejector wouldn't stand up to the strain, and introduced the third cylinder lock on the crane as insurance against the gun getting shaken loose. Half-moon front and notch rear sights, with the two-line address and patent dates on top of the barrel, "44 S&W SPECIAL CTG" on the left, and the large logo on the side plate. Fitted with a casehardened hammer and trigger, and a pair of smooth grips with S&W medallions.
