There are hundreds of variations of the Remington 870 in 12, 16, 20, 28 gauges and .410 bore. In 1969 Remington introduced 28 gauge and .410 bore models on a new scaled down receiver size, and in 1972 a 20 gauge Lightweight version was introduced on the same sized receiver, and all of the smaller gauges today are produced on that size receiver. 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:
- Express – Matte blue/black bead-blasted with hardwood, laminated hardwood or synthetic stocks and chambered for 2 3/4″ and 3″ 12 or 20 gauge shotshells. All Expresses have been chambered in 3″ in 12 and 20 gauge, but markings have varied.
- Marine – Nickel-plated with synthetic stocks.
- Mark 1 – adopted by the United States Marine Corps in the late 1960s and saw service into the 21st century. The Model 870 Mark 1 has a 21 inch (53 cm) barrel with an extended magazine increasing total capacity to 8 rounds, and was fitted with an adapter allowing use of the standard M7 bayonet for the M16 rifle.
- MCS (Modular Combat Shotgun) – A new modular version of the M870 which can be quickly modified with different barrels, magazine tubes, and stocks for different purposes, such as urban combat and door breaching.
- Police – Chambered in 12 gauge only with a 3″ magnum chamber. Blued or Parkerized steel finish. These models feature a stronger sear spring, carrier latch spring, and a forged steel extractor (as opposed to the MIM extractor found on Express models). Receivers are stamped “Remington 870 Police Magnum” as of 2014.
They are equipped with Police-specific walnut or synthetic stocks which are fitted with sling mounts. Walnut stocks lack checkering as found on the Express/Wingmaster models. 870P models come with matching walnut or synthetic forends that are shortened to prevent interference with most vehicle-mounted rack systems. The shortened forend also allows quick visual inspection of the magazine regardless of what position the forend is in, whereas the lengthened sport-type forend on other models partially blocks the loading port when pulled to the rear.
Police models are available with 18″ or 20″ barrels, with or without rifle sights, and have a standard capacity of four rounds. They can be ordered with a two or three round extended magazine tube from the factory, bringing total capacity to 6+1 (18″ barrel) or 7+1 (20″ barrel). All police barrels come with an Improved Cylinder choke unless special ordered.
- Super Mag – Chambered for 3½” 12 gauge shotshells.
- Wingmaster – Blued steel with high gloss or satin walnut stocks. They have been offered in Skeet, Trap, and field configurations. Originally the basic Wingmaster was chambered for 2 3/4″ rounds and came with a fixed choke, and the 3″ chambered versions were designated Magnum models. Models built after 1986 offer the RemChoke Interchangeable choke tube system, and the 12 and 20 gauge versions are chambered in 3″ for either 2 3/4″ or 3″ shells. Prior to the introduction of the “Police” model 870, altered Wingmasters were popular among law enforcement.
