This revolver was conceived as a close-quarters emergency sidearm for British Commandos operating behind enemy lines. It was prototyped at RSAF Enfield in mid-1942, but whether or not it was ever actually fielded is unknown.
The Commando revolver was a double-action 9×19mm revolver based on the 19th century Apache revolver. In place of a conventional grip, it had a folding knuckle duster. It also had a short, hinged blade protruding from underneath the barrel.
