The SLP MK I represents the ultimate in shotgun performance for law-enforcement agencies and officers. Leveraging more than 100 years of autoloading shotgun engineering, the SLP MK I edition features ultra-reliable gas operation, a durable, matte black, aircraft-grade alloy receiver, a synthetic stock, an extended magazine tube, and fully-adjustable rifle sights. The SLP MK I also offers a 22" barrel with a 3" chamber and a hard-chromed bore. Checkered gripping panels on the forearm and grip, interchangeable recoil pads for individual length-of-pull fit, interchangeable comb inserts, and two steel sling swivel studs add to the shotgun's functionality and its extended magazine tube gives it a full 8 + 1 capacity. In addition, the Tactical MK I comes standard with a pistol grip, a forward-mounted MIL-STD 1913 Tri-Rail mount, and a top-mounted cantilever weaver-pattern accessory rail. The sighting system consists of a low-profile, adjustable folding rear blade and a red fiber-optic front.
