Inspired by the very rare and extremely sought-after 1st Generation Colt pistols inspected by US Ordnance Department Principle Sub-Inspector in Charge, Henry Nettleton, Cimarron Firearms recreated the Colt Single-Action Cavalry Model with his unique inspection initials. The Cimarron US Cavalry 1873 Henry Nettleton pays respect to the original 1st generation Colt government models inspected by Henry Nettleton, down to the details of proof marks and all of Nettletons inspection stamps using the exact same fonts and placements as the originals.
