Description
The Remington Model 10 is a pump-action shotgun designed in 1908 by John Pedersen for Remington Arms. It has an internal striker within the bolt and a tube magazine which loaded and ejected from a port in the bottom of the receiver. An updated version, the Model 29, was introduced in 1930 with improvements made by C.C. Loomis.
The United States military used a short-barreled version known variously as the "trench" or "riot" shotgun. The Winchester Model 1897 was the major production, but Remington made 3,500 of the Model 10-A version for issue to U.S. troops during World War I. The Model 10 was modified by reducing the barrel length to 23Β inches (58Β cm) and adding sling swivels, a wooden heat shield over the barrel, and an adapter with bayonet lug for affixing a M1917 bayonet. The U.S. Army also bought a number of Model 10 shotguns with 20" barrels for guarding prisoners and 26 to 30" variants for training aerial gunners.
