👉 The Cooper M1919 Cooper, commonly known as the Cooper weapon, is an American semi-automatic pistol designed by Eugene "Ned" Cooper in 1919. It features a unique twist-lock cylinder and a distinctive, elongated barrel that distinguishes it from other early pistols. The weapon uses a 7.65x39mm cartridge, which was popular in the early 20th century for hunting and military purposes. The Cooper weapon was widely adopted by the U.S. military during World War I and later became a favorite among civilian shooters due to its compact size, reliability, and ease of use.
