caption_attribution_description: Adams revolver An Improved Frame Model of 1854
context_page_description: Robert Adams was a 19th-century British gunsmith who patented the first successful double-action revolver in 1851. His revolvers were used during the Crimean War, the Indian Mutiny, the U.S. Civil War, and the Anglo-Zulu War.
context_section_description: In 1855 a veteran of the Crimean conflict, Lieutenant Frederick E.B. Beaumont, improved the gun by linking the trigger to a spurred hammer, permitting both single- and double-action fire.  A new version of the revolver, the Beaumont–Adams, was produced and became so popular that it is said Samuel Colt was forced to shut down his London manufactory as a result.
