The Triple lock, officially the Smith & Wesson .44 Hand Ejector 1st Model 'New Century', is a double-action revolver. It was and is considered by many, including handgun enthusiast and expert Elmer Keith, to be the finest revolver ever made.^[1]

Its popular name refers to its extra (third) locking lug on the cylinder crane. This extra locking mechanism was deemed necessary due to the increased power of the .44 Special cartridge (a lengthened .44 Russian, and itself the parent of the .44 Magnum), first chambered in the Triple Lock.^[2]

The .44 is part of the model name, regardless of the specific calibre of chambering of any individual revolver, and Hand Ejector is to differentiate the new design from Smith & Wesson's earlier top break revolvers. These 19th-century designs had an automatic ejector mechanism actuated when the frame was tipped up. The newer Hand Ejector models required the user to depress a plunger to eject spent cartridge casings. The New Century designation was in recognition of its status as Smith & Wesson's first 20th century design.

It was only manufactured between 1908 and 1915, for a total of 15,376 revolvers, a stock that sold out completely by 1917. It was replaced by a .44 Hand Ejector 2nd Model, most visibly different in lacking the ejector shroud and third locking lug.

Smith & Wesson changed the design for several reasons. The British and Canadian militaries pressed for the removal of the third locking lug and shroud due to concerns the precision mechanism would collect dirt and malfunction. Additionally, the change simplified manufacturing, allowing Smith & Wesson to drop the price of the gun by $2, from $21 for the 1st Model to $19 for the 2nd Model. The ejector shroud was reintroduced in 1926, with the Hand Ejector 3rd Model, but the Triple Lock feature was never used again.

British and Commonwealth Great War service

To cover manufacturing shortages of the Webley Mk VI, early in the war the Ministry of Munitions contracted Colt and Smith & Wesson to manufacture revolvers chambered in .455 Webley. Smith & Wesson were given an initial contract to manufacture 5,000 triple lock pistols, known as the Pistol Smith & Wesson .455 with 61⁄2 inch barrel Mark 1, it was introduced into British service as a "substitute standard" sidearm on 5th July 1915 alongside the Colt New Service. Subsequent orders, lacking the third locking lug and ejector shroud, totalled 69,755 and were known as the Mark 2.^[3]
