About

What it is, and why it matters

Copy a link to this section

The Colt 1878 Frontier is a six-shot, double-action revolver introduced by Colt in 1878. Chambered most notably in .45 Colt, it was Colt's first large-frame double-action revolver and the company's principal double-action offering until the 1889 Navy. It shared its cylinder-forward components with the single-action Colt Single Action Army and used a birdshead grip, a side-loading gate, and an ejector rod. Often called the 'Double Action Army' or 'Frontier', it was produced until 1907.

The Model 1878 was the only major American double-action revolver from 1878 until the .38-caliber Colt Model 1889 Navy, filling a critical market gap during the late 19th century. Notable owners included Buffalo Bill Cody and Pawnee Bill.

Available in a wide range of barrel lengths from 2.5 to 12 inches and numerous chamberings including .32-20, .38-40, .44-40, .45 Colt, and several British calibers. A long-barreled, smooth-handle variant known as the Model 1902 Alaskan/Philippine model was supplied to U.S. forces during the Philippine-American War.
