Development

The Remington 870 was the fourth major design in a series of Remington pump shotguns. John Pedersen designed the fragile Remington Model 10 (and later the improved Remington Model 29). Working with John Browning, Pedersen also helped design the Model 17^[4] which was adopted by Ithaca as the Ithaca 37 and also served as the basis for the Remington 31. The Model 31 was well liked,^[5] but struggled for sales in the shadow of the Winchester Model 12. Remington sought to correct that in 1950 by introducing a modern, streamlined, rugged, reliable, and relatively inexpensive shotgun - the 870 Wingmaster.

Sales of the 870 have been steady. They reached 2 million guns by 1973 (ten times the number of Model 31 shotguns it replaced). By 1996, spurred by the basic "Express" model, sales topped seven million guns. On April 13, 2009 the ten millionth Model 870 was produced, and the 870 holds the record for best-selling shotgun in the history of the world.^[6]

Design details

The 870 features a bottom-loading, side ejecting receiver, tubular magazine under the barrel, dual action bars, internal hammer, and a bolt which locks into an extension in the barrel. The action, receiver, trigger system, safety catch and slide release catch of the Remington Model 870 shotgun are similar to those used on the Remington Model 7600 series pump-action centerfire rifles and carbines. The trigger group itself was first used in the automatic 11-48.^[7] 20 gauge stocks will also interchange. Several parts of the 870 will interchange with the semi-automatic Remington 1100 and 11-87.

The original 870 models were offered with fixed chokes. In 1986 Remington introduced the new Remington "Rem Choke" system of screw-in chokes (also fitted to Remington model 1100 auto-loading shotguns at the same time). Initially, the Rem Chokes were offered on barrel lengths of 21, 26 and 28". It was not offered on 30" barrels, deer guns, target guns or as a retrofit.

Early production 870s had a design flaw whereby a user could either "short stroke" the action - not pull the forearm all the way back while cycling the action - or fail to press a shell all the way into the magazine when loading.^[8] This would cause the gun's action to bind, requiring rough treatment of the action or even disassembly to clear. The issue was resolved with the introduction of the "Flexi Tab" carrier. Guns with this modification can be identified by the "U"-shaped cut-out on the carrier, visible from below the gun. The cut-out allows the round to ride over the carrier without binding the action.

Variants

There are hundreds of variations of the Remington 870. From the original fifteen models offered, Remington currently produces dozens of models for civilian, law enforcement, and military sales. 870 variants can be grouped into:

• Wingmaster – Blued steel with high gloss or satin walnut stocks. Originally the Wingmaster was only chambered for 2 3/4" rounds and came with a fixed modified choke. Models built after 1986 offer the RemChoke Interchangeable choke tube system, the 12-gauge model chambered in either 2 3/4" or 3". Prior to the introduction of the "Police" model 870, altered Wingmasters were popular among law enforcement.
• Police – Blued or Parkerized steel with satin walnut, stained hardwood, or synthetic stocks. Action parts are heavy-duty and these models receive extra care and inspections during assembly. Also has an extended tube magazine.
• Marine – Nickel plated with synthetic stocks.
• Express – Matte black bead-blasted with laminated hardwood or synthetic stocks.
• Express Magnum - Matte black bead-blasted with laminated hardwood or synthetic stocks and chambered for 2 3/4" and 3" 12 gauge shotshells.
• Express Super Magnum – Matte black bead-blasted with laminated hardwood or synthetic stocks and chambered for 3½" 12 gauge shotshells.
• XCS - TriNyte coated external metal and nickel plated internals with speedfeed stocks.
• MCS(Modular Combat Shotgun)(Now KAC Masterkey) - Underslung shotgun used on assault rifles.

Chinese M870

China has made unlicensed M870 copies by Norinco as the Norinco HP9-1 and used by the People's Liberation Army as the standard shotgun.

However, the M870 copy is a widely-distributed design no longer under patent protection, and most parts interchange freely. In the United States, where Norinco products are specifically non-importable, this gun is imported and sold under the names Norinco Hawk 982 and Interstate Hawk 982.
