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

These were stamped "U.S. Property" on the left side of the receiver and had an approximate serial number range of 51000–63000. Except for a single prototype, no Model 31 trench guns were produced. 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.Simpson, Lane.

Notable differences are the use of a two-piece bolt with separate locking piece as well as a significantly simplified barrel mounting system. Further, the bolt locks into a barrel extension rather than directly to the receiver.
