Remington 870 Police Magnum 12 Gauge – Police Trade-In

About this product

The Remington 870 Police Magnum is the heavy-duty, agency-issue variant of the 870 pump shotgun, built with a parkerized finish, steel trigger group, extended magazine tube, and synthetic stock and forend for duty use rather than sporting use. This listing is genuine law-enforcement trade-in stock — real agency guns that were carried and racked for years, not new-manufacture reproductions of the Police pattern. Every gun is bore- and action-inspected before sale, and configuration varies by the agency it came from.

What is it used for?

Home defense and duty-style use are its core purpose — the Police variant was built specifically for agencies that needed a shotgun to survive years of rack storage, patrol-car vibration, and hard use, and that same toughness carries over to a home-defense role. It's not built or finished for sporting clays or hunting; the parkerized finish and fixed cylinder-bore barrel are duty features, not field features.

How does it compare to a new-production 870?

Trade-in Police guns get you the tougher agency-spec parts — steel trigger group, extended magazine tube, tighter fitting — at a lower price than a comparable new-production model, in exchange for honest cosmetic wear from real service use. Mechanically these were maintained and inspected on a duty cycle, which for many buyers is a selling point, not a downside, since it means the gun has already proven itself under hard use.

What fits it?

Barrel length runs 18 or 20 inches depending on the specific agency configuration, with either bead or rifle sights and a four- or six-shot extended magazine tube — ask us for photos of the specific gun before ordering if a particular configuration matters to you, since trade-in stock varies unit to unit. Standard 870 aftermarket parts, sights, and stocks are broadly compatible with the Police pattern's core action.

Who is this not for?

If cosmetic condition matters more to you than mechanical soundness, know upfront that these show honest holster and rack wear on the outside — scuffed parkerizing, handling marks — even though the bore and action are inspected and function-guaranteed. It's also not a hunting gun as configured; the cylinder-bore barrel and duty sights aren't built for wingshooting.

Does it work in California?

Shotguns still ship to your FFL dealer, and overall-length and configuration rules for California delivery are confirmed with the dealer at transfer, same as any other long gun purchase — see our California gun laws page for the current process. Because configuration varies by trade-in unit, we'll confirm your specific gun meets state requirements before it ships.
