The Ithaca 37, a manually operated, pump-action shotgun, is based on the 1915 design of John Moses Browning and John Pedersen in 1933. Production began in 1937 and was geared not only for military, but also targeted civilian and police markets. Ithaca Gun Company, however, chose to wait until patents expired before introducing their design.
Though intended as a sporting arm, the introduction came during the depression with thoughts of war on the forefront of everyone’s mind. Ithaca did, however, manufacture some shotguns for the US military during WWII, along with the M1911 pistol and the M3 Grease Gun. At the end of the war, they once again began production on the Model 37. The company itself has changed ownership a number of times over the years.

With bottom shell loading and ejection, the Ithaca 37 is an ideal weapon for either a right or left-handed shooter. A number of versions are available including a 28-gauge, a 12-gauge built for the purpose of home defense and a shorter stakeout version with a pistol grip stock.
The United States Military is the single largest user of the Ithaca 37, who used it in both World War II and the Vietnam War. This shotgun is also used by the LA Police Department and a number of other police and security agencies. Even though production briefly stopped in 2005 when the company changed ownership, production run of the Ithaca 37 surpassed even that of the Winchester Model 37, crediting it with the longest manufacturing run for a pump-action shotgun. Currently, production facility for the Ithaca Model 37 pump-action shotgun is located in Ohio.
