The Remington Arms company began production of 1858 New Army single action revolvers, and five years later the single action army had gained a foothold. In 1863, an improved version of the rugged .44 caliber, also known as the Remington-Beals revolver, was purchased by the U.S. Army. In the years following the Civil War, the black powder firearms maker also manufactured a carbine version of the 1858 New Army, the 1858 Target Carbine, in smaller numbers. The 1862 Police revolver was designed by Colt in response to civilian demand for pocket pistols. Colt made scaled-down versions of its 1851 Navy and 1860 Army revolvers, both chambered in .36 caliber. The redesign of the 1860 Army Colt revolver yielded the 1862 Police single action, with a fluted cylinder.
