Remington Model 10

The Remington Model 10 is a pump-action shotgun designed in 1908 by John Pedersen for Remington Arms. Its internal striker sits within the bolt, and its tube magazine is loaded and emptied through a port in the bottom of the receiver. Remington updated the design as the Model 29 in 1930, with improvements by C.C. Loomis. The gun also had a military career. For the First World War Remington made 3,500 of the Model 10-A for issue to United States troops, with the barrel cut to 23 inches, sling swivels, a wooden heat shield over the barrel and an adapter carrying a lug for the M1917 bayonet; these trench or riot guns were stamped with the US mark and the flaming bomb on the receiver. A trench version for the Russian army, built for the Mosin-Nagant bayonet, was never adopted after the Imperial government fell. Other Model 10 guns with 20-inch barrels guarded prisoners, and 26 to 30 inch barrels trained aerial gunners. The Marine Corps used the Model 10-A in limited numbers through the 1930s.
