Approximately 25,000 Model 1875s were manufactured between 1875 and 1889. They were among the first and most widely used centerfire revolvers in the West and are particularly known for their use by the Indian Police. They were also known as the Improved Army or Frontier Army. The top of the barrel is marked "E. REMINGTON & SONS. ILION. N.Y. U.S.A." The front flat of the frame at the breech on the left side is stamped "44," the caliber designation for .44 W.C.F. The revolver features a blade front sight, a frame notch rear sight, the standard web-contoured ejector rod housing, and a fluted cylinder. The serial number is marked on the left side of the grip frame, the loading gate arm, and the trigger guard. Instead of a lanyard loop, the butt has two non-factory empty holes.
