Springfield “Trapdoor“ Model 1873

The Model 1873 “Trapdoor“ Springfield was the first standard-issue breech-loading rifle adopted by the United States Army (although the Model 1866 trapdoor had seen limited issue to troops along the Bozeman Trail in 1867). The gun, in both full-length and carbine versions, was widely used in subsequent battles against the American Indians. The Model 1873 was the fifth variation of the Allin trapdoor design, and was named for its hinged breechblock, which opened like a trapdoor. The infantry rifle model featured a 325⁄8-inch (829 mm) barrel, while the cavalry carbine used a 22-inch (560 mm) barrel. It was superseded by an improved model, the Springfield Model 1884, also in .45-70 caliber. Use in Wars: Great Sioux War, Indian Wars, Spanish--American War, Philippine--American War
