Colt New Service

The Colt New Service was produced for government contracts and civilian sales between 1898 and 1944. It came in a plethora of popular calibers available during its lengthy production run and was also available in a number of finishes and barrel lengths. The revolver was most commonly chambered in a variety of .45 caliber rounds, including ACP and Colt. It served American forces during the First World War and accompanied many police officers in their duties throughout the first half of the twentieth century.

A Colt New Service was used to classify any new model of Colt revolver issued to Army forces. They were built in the .38 long colt (pre .38 special) model made in 1898, the .357 magnum model made sometime in 1935-1936, a .44-40 model, a .44 special model, a .38-40 model, a .45 Long Colt and a .45 caliber ACP model built for the military, the M1917. Because the U.S. Army had already adopted the M1911A1 pistol in 1911, which took a .45 ACP round, they needed to build a gun capable of firing this new round as a rimmed .45 Long Colt round would cost too much to bring into production, so they built half and full moon clips which clamped 3 or 6 rounds of .45 ACP together and acted as a rim for the automatic cartridge, allowing the 1917 to fire .45 ACP rounds. A .45 long colt round, while dimensionally capable of fitting the chamber of a 1917, it is too long to fit the cylinder, meaning this gun is actually meant to only fire .45 ACP. The only cartridge capable of fitting the cylinder is a .45 long colt blank.
