The '''.45 Colt''' (11.43×33mmR), often called the '''.45 Long Colt''', is a rimmed straight-walled handgun cartridge dating to 1872. It was originally a black-powder [[revolver]] [[Cartridge (firearms)|round]] developed for the [[Colt Single Action Army]] revolver. This cartridge was adopted by the [[U.S. Army]] in 1873 and served as an official US military handgun cartridge for 19 years, before being replaced by the [[.38 Long Colt]] in 1892. Although there has never been a ".45 Short Colt" cartridge, the .45 Colt is frequently called the ".45 Long Colt" (.45 LC) to better distinguish it from the shorter and less powerful [[.45 Schofield]] cartridge, which was also in use around the same time as the .45 Colt.
