130 manufactured in 1944 by the Sterling Armament Co. in Dagenham, East London, United Kingdom. .45ACP subsonic, 7-round standard pistol magazine, bolt action, integral suppressor. This fascinating weapon was developed by William Godfray de Lisle, British engineer at the Air Ministry, between 1942 and 1944. Its suppressor, an improvement over Hiram Percy Maxim’s silencer, made it inaudible beyond 45m, a quarter of its effective range. It was an invaluable asset for British commandos and a much better alternative to the Welrod pistol that could only fire a few rounds at very short range before needing repair.
