You are all probably familiar with the standard Remington 870 shotgun. But there are also other versions of the shotgun model including the Remington 870 Express and the Remington 870 Police. The main differences between these two shotguns have to do with the parts that they’re comprised of and how they’re assembled. Remington 870 Police shotguns go through a more thorough quality control inspection before they are released. Aside from a visual inspection, the functionality of the shotguns is tested along with their firing capabilities. Once that is done, they go through one more final inspection before they get approved. The 870 Police shotguns are built in a highly secured area of a weapons plant located in Ilion, New York. This is an area that only creates military and law enforcement shotguns.

In a nutshell, the 870 Police is more reliable than the 870 Express for obvious reasons. Law enforcement officers require a dependable weapon because they are often faced with life or death situations. The 870 Police shotgun utilizes longer magazine spring. It has the heavy carrier dog spring. As well as the heavy sear spring which provides a more reliable trigger pull. The forends of the 870 Police are smaller than the 870 Express. And when you want to add an extension tube to the police version, you won’t have to physically modify the magazine tube of your weapon like with the express version. Most importantly, the 870 Police shotguns have no integrated safety system installed in them like the Express 870 does. This safety system is an extra locking mechanism that is integrated into the safety, which can delay the shooter when firing the weapon. Since the 870 Police shotgun doesn’t have that, then it won’t slow the police down when having to shoot in a critical encounter.

The Remington 870 Police shotguns are not made available to law enforcement and military officers only. You can buy them as any other Remington 870. You can also upgrade your Remington 870 Express with parts from a Remington 870 Police. In fact, it is quite easy to get the Remington 870 Police parts and then install them on your Express shotgun. You can find them for sale at gun shows or at gun shops all across the United States.

Here is list of differences between Remington 870 Express and Remington 870 Police. Most of the parts which are used on Remington 870 Police are easy to get and install on the Express version of a shotgun.

  • 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 an officer 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.
