-“Pistol Cases: The Army’s Earliest Hip Holsters”, Lee A. Rutledge, The Gun Report
, September 1990.
“Writing in 1856, George B.McClellan, then a captain with the First U.S Cavalry, and recently an observer of the Crimean War, remarked ‘For my own regiment, armed with revolvers, there need be no [pommel] holster, for the men should follow the Russian system and always carry the pistol on the waist belt.’ That same year, the army contracted with civilian manufacturers for nearly 3,400 ‘pistol cases'’’ for Colt navy and dragoon revolvers. -Packing Iron: Gunleather of the Frontier West
