The civilian 1860 revolvers were produced in .44 Colt centerfire only; the 1851 and 1861 revolvers were produced initially only in .38 rimfire. In 1873, the Navy contracted with Colt to convert a number of their service Model 1851 and Model 1861 percussion revolvers to use a .38 caliber centerfire cartridge that did not yet exist, but which the Union Metallic Cartridge Company was in the process of developing. That cartridge was in production by late 1873 or early 1874 as the .38 long centerfire, which was a centerfire version of the .38 long rimfire, the dimensions of the two being quite similar.
