The '''Colt Frontier''' or '''Frontier Six-Shooter''' was a Colt's 1873 "Model P" type revolver manufactured in .44-40 Winchester caliber instead of .45 Colt (in which configuration it was called the ''Single Action Army'') so that it was compatible with Winchester [[Winchester rifle|Model 1873]] ammunition. Production began in 1877. ''Colt Frontier Six-Shooter'' was the actual name of the Colt pistol model, and this was acid-etched on the left side of the barrel. After 1889, the legend was roll-stamped until 1919, when the caliber designation ".44-40" was added. Later [[Colt M1878]] Double Action Army Models also wore this designation on the barrel when chambered in .44 WCF/.44-40 Winchester. The Bisley 1895 Model was the final Colt to wear the Frontier Six Shooter designation.<ref name=taffin4041>Taffin (2005) pp. 40–41</ref>

The 44-40 was also promoted as the standard chambering for the new, hugely successful, Winchester Model 1873 rifle. Users of the .44-40 Winchester cartridge in the Far West appreciated the convenience of being able to carry a single caliber of ammunition, which they could fire in both revolver and rifle. The ''Colt Frontier Six Shooter'' Revolver and the Winchester Model 1873 or the [[Winchester Model 1892]] in .44-40 WCF caliber was one of the most common combinations seen in "the Old West".<ref name="taffin4041" /> For example, the two mounted "Cowboys" at the [[Gunfight at the O.K. Corral]] were armed with this rifle and pistol combination. [[.38-40 Winchester|.38-40]] and [[.32-20 Winchester|.32-20 (.32 WCF)]] also qualify as "Frontier Calibers" because 1873 and 1892 Winchesters were made in these calibers, offering the same convenience as the 44-40 (44WCF) caliber, namely using the same cartridge in both revolver and rifle.
