Description
The Ithaca 37, also known as the Ithaca Model 37, is a pump-action shotgun made in large numbers for the civilian, law enforcement and military markets. Based on a 1915 patent by firearms designer John Browning for a shotgun initially marketed as the Remington Model 17, it utilizes a novel combination ejection/loading port on the bottom of the gun which leaves the sides closed to the elements.
The Model 37 was used by the United States Armed Forces in World War II, the Korean War, and especially the Vietnam War, where it gained a great reputation for reliability in the jungles of Vietnam when generally used by special and special operations forces like the Navy SEALs and Army Green Berets.
Stakeout: short version with a 13-inch (330 mm) barrel and pistol grip stock. Because of its barrel length and overall length, this model is classified as a National Firearms Act 'any other weapon'
