The Model 870 “Wingmaster” was introduced by Remington in 1950 and has since gone on to becoming one of the most popular American made pump action shotguns ever produced. The Model 870 was intended to be a reliable, rugged, and relatively inexpensive replacement for the Remington Model 31 in order to rival sales of the Winchester Model 12. While initially marketed to hunters and sport-shooters, the versatility of the gun and the various configurations offered aided in the gun’s adoption in the law enforcement community. Nearly every police department in the United States fields a variant of the Remington 870. Additionally, the Remington 870 was officially adopted by US Military in the early 1970s.
