Sometimes referred to as a “Trench Gun” (in relation to Trench Warfare), The Browning Auto Shotgun was one of the first “combat shotguns” used by The US Army during World War I. Although Browning's Shotgun design was first developed in 1905, by America's involvement in The War (and the reality of Trench fighting), Browning developed this weapon. Weighing only 9 pounds, the weapons could chamber (5) 16-Gauge shotgun shells. The average Browning was 50-inches long, but many versions were illegally “cut down” by serving Soldiers to fit their needs in battle. Issued to mostly Non-Commissioned Officers, The Browning Auto Shotgun was an important piece of American Trench Warfare fighting equipment. The Auto 5 remained in production until 1998 (still used by many Armed Forces and Polices Agencies Worldwide).
