The Winchester Model 1873, known as "The Gun That Won the West," was one of Winchester's most successful lever-action rifles, produced between 1873 and 1923. Initially chambered for the .44-40 cartridge, the first centerfire round manufactured by Winchester, it quickly gained popularity for its reliability and versatility. The Model 1873 was later available in .38-40 and .32-20, which were also popular in handguns, allowing users to carry a single type of ammunition. The rifle was offered in three main configurations: a 24" barrel rifle, a 20" carbine, and a 30" musket variant aimed at military contracts. While the standard rifle was the most popular, custom configurations with features like octagonal barrels and engraved receivers were available. Modern reproductions of the Model 1873 continue to be produced, celebrating its legacy with versions like the 150th Anniversary Edition featuring a blued steel receiver, Grade V/VI walnut stock, and octagon barrel. Other modern variants include the Short Rifle, featuring a case-hardened receiver and classic round barrel, and the Deluxe Sporting, which boasts a half-octagon, half-round barrel and a refined walnut stock. These reproductions maintain the original design's aesthetics but incorporate modern safety improvements, including a firing pin block and a modified cartridge carrier to eject casings more efficiently. Today, the Model 1873 continues to thrive in cowboy action shooting and remains a cherished piece of firearms history.
