Overview

The Adams Navy Revolver is a British-designed, American-made double-action percussion revolver chambered in .36 caliber, the Navy-bore version of Robert Adams's solid-frame self-cocking design. Built under license by the Massachusetts Arms Company of Chicopee Falls, it combined Adams's one-piece frame and rapid trigger-cocking action with the same .36 belt-pistol caliber as the Colt M1851 Navy. The US Ordnance Department took delivery of roughly 500 examples in 1857-1858, and a number saw service with Union forces in the opening years of the American Civil War, prized for the speed of fire that double action gave over single-action Colts.

Notes

The .36 'Navy' caliber Adams was produced in the United States by the Massachusetts Arms Company under license from Robert Adams, distinct from the larger British .442 (54-bore) and .500 (38-bore) service models made by Deane, Adams & Deane. It featured a 6-inch octagonal barrel and a five-shot cylinder. Total US production is estimated at around 1,000-1,500 revolvers.

Background

When the US Army trialed revolvers in the late 1850s, the .36 Adams from Massachusetts Arms offered something Colt could not: a true double-action trigger that fired as fast as a man could pull, a feature that would not become standard on American service revolvers for decades.
