Remington Model 31

The Remington Model 31 is a pump-action shotgun that competed with the Winchester Model 1912 for the American sporting arms market. Produced from 1931 to 1949, it superseded the John Pedersen-designed Model 10 and Model 17 and was replaced by the less expensive Remington 870.

History
While the Remington Model 17 enjoyed some success, a solid, 12-gauge featuring side-ejection was needed to compete with Winchester. C.C. Loomis sized up the Model 17 and adapted it for side ejection. The Model 31 was Remington's first side ejecting pump-action shotgun. Stocks were walnut with checkered walnut forend and later changed to a ribbed forend. The Model 31 was made in three gauges with 121,000 12-gauge models made and 75,000 16- and 20-gauge examples also produced. The Federal Bureau of Investigation acquired one Model 31 per office in 1935 in response to the Kansas City Massacre.

Despite being well received, sales still lagged far behind the Winchester. Remington went back to the drawing board and designed the Model 870; this shotgun matched the durability of the Model 12 at a significantly lower cost. Despite the overwhelming success of the 870, many shotgun connoisseurs consider the Model 31 to be the ne plus ultra of pump shotguns with its "ball-bearing" slide action.

The Model 31 was later used as a basis for the modernized and simplified Mossberg 500, 590, 835 and Maverick 88 shotguns. The biggest differences being the use of aluminum alloy receivers in most variants.
