The Remington 870 was the fourth major design in a series of Remington pump shotguns. John Pedersen designed the fragile Model 10 (and later the improved model 29). Working with John Browning, Pedersen also helped design the Model 17 which was adopted by Ithaca as the Ithaca 37 and also served as the basis for the Remington 31. The Model 31 was an excellent shotgun, but struggled for sales in the shadow of the Winchester Model 12. Remington sought to correct that by introducing in 1950 a modern, streamlined, rugged, reliable, and relatively inexpensive shotgun, the 870 Wingmaster. John Douglas Pederson was a prolific arms designer from Wyoming. ... John Moses Browning (January 21[1] or January 23,[2] 1855 – November 26, 1926), born in Ogden, Utah, was an American firearms designer who developed myriad varieties of weapons, cartridges, and gun mechanics, many of which are still in use around the world. ... // Description The Ithaca 37 is a pump-action shotgun made in large numbers for the civilian, military, and police markets. ...

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. The 870 holds the record for best-selling pump gun in U.S. history.[1]


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 centrefire rifles and carbines. 20 gauge stocks will also interchange. Several parts of the 870 will interchange with the semi-automatic Remington model 1100 and 11-87, and some aftermarket accessories will fit all 3 (such as sidesaddle shell carriers).

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– high-end sporting line, with polished bluing and glossy wood finishes.
  • Express – low-cost entry-level line, bead blasted finish and satin wood or synthetic furniture. It was designed to meet a price point in the commercial market, and is thus made in a less expensive manner than 870 Police and Wingmaster models (for example, 870 Police shotguns use machined ejectors and extractors, as opposed to powdered metal cast which are utilized on the Express models).
  • Marine – synthetic stocks and nickel finishes. Designed for maximum corrosion resistance.
  • Police – manufactured in a more costly manner that results in a considerably more expensive but also more durable firearm. Available with bead, rifle, and ghost-ring sights. Comestically, available with high luster blued or parkerized finish and satin wood or synthetic stocks. Intended primarily for the law enforcement and military markets.
  • Tactical - combat models intended primarily for the private sector market, built in the same low-cost manner as Express shotguns, and not like the heavier-duty (and more expensive) Police shotguns
    • All black in colour.
    • 18" or 20" barrel.
    • Improved cylinder and recoil pads to absorb impact.
    • Eight-round capacity with two or three round extensions available.
    • Three additional stock options (pistol grip and pistol grip with two types of folding/collapsible stock).
  • "MCS" -The "Modular Combat Shotgun" is designed to be quickly modifed to suit a user's tactical needs. It can be configured into five different formats.
    • Patrol Gun with a 18" barrel and a 6-shot magazine
    • Entry Gun with a 14" barrel and a 5-shot magazine
    • Vehicle Support Weapon with a 10" barrel and a 3-shot magazine
    • Breacher tool with a 10" barrel, pistol grip, and no buttstock.
    • Accessory Weapon with mount to be mounted under a M16 rifle like a KAC Masterkey.

Parkerizing (sometimes called phosphating) is a method of protecting steel surfaces from corrosion and thus increasing their durability. ... M16 (more formally United States Rifle, Caliber 5. ...

Differences Between the 870 Express and 870 Police

The 870 Express has been an important part of Remington’s offering to the sporting market. It was designed to meet a price point in the commercial market while still providing 870 functionality. All of Remington’s 870’s have interchangeable parts, even if they have cosmetic differences. It is also important to note that many custom/semi-custom manufacturers (including Wilson Combat) use the 870 Express platform for their "Police" / "Combat" models. While the 870 Express is still an 870, there are some very important cosmetic and functional differences between it and the 870 Police. To users whose lives depend upon the unfailing performance of their shotguns, the Police modifications are of paramount importance. Synopses of the variances are provided below.

  • 870 Police shotguns go thru a special 23 station check list – ranging from visual inspection, functional testing, test firing, and final inspection.
  • All Police shotguns are assembled in a “special build area” at the plant in Ilion, NY. This section is secured and serves only to build LE and Military shotguns, with the same factory personnel working at that assignment each shift.
  • All parts that enter the “special build area” are visually inspected by hand to ensure top quality and functionality.
  • Due to heavy recoil in buck and slug loads, all 870 Police guns have a longer magazine spring which ensures positive feed and function.
  • A heavier sear spring is used to generate a reliable, positive trigger pull between 5 and 8 lbs.
  • A heavier carrier dog spring is used to ensure when the carrier elevates the shell, it will be held there until the bolt can push it into the chamber. This ensures positive feeding when using heavier payload rounds.
  • Police shotguns do not have an ISS (Integrated Safety System) which is a locking mechanism on the safety of commercial shotguns. This type of locking mechanism can cause delay to the operator who needs the weapon but does not have the appropriate key. LE shotguns have the standard, proven, cross bolt safety.
  • The fore-end on the Express model is longer and not compatible with many police shotgun vehicle racks.
  • The Police shotguns utilize the heavy duty SPEEDFEED Stocks and Fore-ends.
  • The Express model will not allow for the addition of an extension tube without physical modification to the tube and barrel, which can nullify the warranty.
  • The Express model has a BEAD BLAST BLUE finish while the Police models utilize either High Luster bluing or Parkerization.
  • The Express model utilizes a synthetic trigger housing while the Police models use a compressed metal housing.
  • The Police shotgun barrel is locked down with a “ball detent” system in conjunction with the magazine cap vs. a lesser grade “synthetic magazine spring retainer” lock down as used on the Express system.
  • The receivers used in Police guns are “vibra honed” to smooth out rough finishes and remove burrs before parkerization or bluing.
  • Police shotguns use machined ejectors and extractors, as opposed to powdered metal cast which are utilized on the Express models.
