The Police Magnum configuration brings duty-focused features to the proven 870 platform. The receiver is marked "Remington 870 POLICE MAGNUM," and the serial suffix "M" denotes a 12 gauge magnum receiver, aligning with its 2 3/4 in and 3 in chambering. Capacity is 6+1 via the tubular magazine and 2-shot extension that terminates flush with the muzzle.
Construction is centered on a steel receiver with a matte parkerized gray/green finish for reduced glare. The receiver top is drilled and tapped with two holes (no mount installed). The barrel carries the REP oval proof mark, and ejection is to the right side.
Furniture consists of a wood stock and a long-pattern wood fore-end. The stock features checkering for grip and a rubber Remington buttpad. Sight picture is straightforward with a single front bead on a low ramp and no rear sight. Length of pull is 14.0.
