The 1873 Springfield Trapdoor was the US military's first widely adopted metallic cartridge breech-loader, serving from 1873 to 1892. It fired the .45-70 Government cartridge, initially with a 405-grain bullet and 70 grains of black powder.

Though Colt produced 30,000 units, it was quickly superseded by the Berdan II, making surviving examples rare.
