Description
The sound of a Remington 870’s pump-action being racked is universally understood. It’s the sound of a problem being solved before a shot is ever fired. When it comes to home defense or duty use, you don’t need complexity—you need proven, mechanical reliability that works when your heart is pounding. That’s the entire purpose of the Remington 870 Police Pump 12 Ga, 18″, 3″, Walnut Stock, 6rd. This is the same platform trusted by law enforcement and military units for decades, now configured for the responsible citizen. It’s not a sporting gun adapted for defense; it’s a duty-grade tool built from the ground up for the most critical scenarios.
What is the Remington 870 Police Pump 12 Ga, 18″, 3″, Walnut Stock, 6rd? It is a law enforcement-grade, pump-action shotgun with an 18-inch barrel, chambered for 3-inch 12-gauge shells. It features a classic American walnut stock and forend, a 6-round capacity, and is built to military and police specifications for maximum durability under stress. This model is ready for duty, home defense, or tactical training straight from the case.
Built for the Moment of Truth
This isn’t a range toy. The 870 Police model is assembled with heavier-duty components, including a machined steel receiver, a parkerized finish that resists corrosion, and an action that’s honed for smooth, positive cycling under pressure. The 18-inch barrel provides the ideal balance between maneuverability in tight spaces and effective shot patterning. At just over 37 inches in overall length, it won’t snag on doorframes but still offers a solid shooting platform. The walnut stock isn’t just for looks—it provides a heft and stability that synthetic stocks sometimes lack, absorbing recoil and giving you a firm, confident grip. Here’s the thing—when you need it, you need it to work. Period. This shotgun’s reputation is built on that single, non-negotiable point.
Simplicity is the Ultimate Sophistication
There are no batteries, no optics to zero, and no complex manual of arms. The controls are instinctive: pump, fire, repeat. This simplicity translates to reliability. The 6-round capacity (5+1) gives you multiple engagements without being overly bulky, and the 3-inch chamber allows you to select from a vast array of 12-gauge loads, from low-recoil buckshot to powerful slugs. The steel receiver is drilled and tapped for optics, but the classic bead sight is more than adequate for defensive distances. With a total weight around 7.5 pounds, it’s substantial enough to manage recoil but not so heavy it becomes a burden during extended readiness.

Pros & Cons
Pros: Legendary reliability and durability. Intuitive, simple manual of arms. The 18″ barrel is the legal minimum without NFA paperwork, offering maximum maneuverability. The walnut stock provides classic aesthetics and solid recoil management. Massive aftermarket support for lights, slings, and side-saddles—compatible with popular accessories from brands like Streamlight and Mesa Tactical. It’s drop-in ready for its role with no gunsmithing required.
Cons: Heavier than some modern polymer/tactical shotguns. The parkerized finish, while tough, requires more maintenance than modern coatings like Cerakote to prevent rust. Pump-actions require practice to master under stress compared to semi-automatics.
Who Is This For?

Priced at $590.78, it represents a significant value for a duty-grade firearm that ships to Missouri and compliant US states.
Frequently Asked Questions
Q: What is the difference between the 870 Police and a standard 870 Express?
A: The Police model uses higher-grade metal finishing, more rigorous fitting and testing, and often includes heavier-duty internal components like the shell latches and ejector. It’s built to a more demanding specification for institutional use, which translates to greater long-term durability.
Q: Can I use 2.75-inch shells in this 3-inch chamber?
A: Absolutely. A 3-inch chamber safely fires standard 2.75-inch (often called 2 3/4-inch) shells all day long. The 3-inch designation simply means it can also chamber the longer, more powerful 3-inch magnum shells if you choose to use them.
Q: Is it difficult to add a side-saddle or a light?
A: Not at all. The 870 is one of the most accessorized firearms in history. Adding a simple, bolt-on side-saddle shell carrier or a clamp-mounted flashlight to the magazine tube is a straightforward process that requires basic tools and no permanent modification to the shotgun.
