The Remington New Model, was a percussion revolver manufactured by Eliphalet Remington & Sons in .36 (Navy) or .44 (Army) caliber revolver used during the American Civil War. The Remington revolver was a secondary, supplemental issue firearm for the Union Army until the Colt factory fire of 1864. Due to the fire, the preferred Colt 1860 Army was not available for some time, and large numbers of the Remington revolver were ordered by the U.S. government as a substitute. It was expensive and those who could afford it remarked on its durability and ability to quickly reload by switching to another pre-loaded cylinder.
