The Remington Model 11 Sportsman was a semi-automatic shotgun manufactured by Remington Arms. It was the civilian model of the military Model 11, which was used by American troops during World War II. The gun held two cartridges and was designed for 12-, 16- or 20-gauge bullets.
The Model 11 is a variation on the Browning Auto-5, designed by John Browning in 1898. During the 100 years it was in production, the Browning Auto-5 design was made by several companies. Remington owned the license to the design between 1905 and 1947, and the Model 11 was the first auto-loading shotgun manufactured in the United States. The Sportsman variation of the Model 11 featured a shortened magazine to keep it in compliance with hunting laws.
