Reproduction Colt Navy revolvers are modern copies of the classic 1851 .36-caliber cap-and-ball revolver, produced by contemporary manufacturers using current materials and tooling. Original 19th-century revolvers were made between about 1850 and 1873 and are now high-value collector pieces, while reproductions let shooters enjoy the same general design and handling at a more accessible price and without risking wear on an antique.
