As a result, in 1949, Remington decided to introduce a more modern, streamlined, rugged, reliable, and relatively inexpensive shotgun, which later became the Model 870. The latter was well-liked but struggled for sales in the shadow of the Winchester Model 12.
The Remington Model 870 was the fourth major design in a series of Remington-designed pump-action shotguns, after the Model 10, the Model 29, the Model 17, and the Model 31.
