Built by Howa in Japan for Mossberg, this Model 1000 Super 20 carries clear factory markings and proofing that speak to its origin: "MADE IN JAPAN BY HOWA" and "MADE BY HOWA IN JAPAN FOR MOSSBERG," along with "PROOF TESTED." The lineage traces to the S&W Model 1000 design, giving it a known and respected foundation.
The 26 inch barrel features a ventilated rib with a matted top for glare reduction and an interchangeable screw-in Multi-Choke system, providing practical versatility. A simple front bead offers a clean sight picture. The "Super" designation denotes its 3 inch chamber capability in 20 gauge.
Operation is gas-operated and semi-automatic, with right-side ejection and a right-side charging handle. The tubular magazine provides 4+1 capacity, aligning with the shotgun’s straightforward field-ready configuration.
Stocked in select walnut, the pistol-grip buttstock and matching forend feature cut checkering for secure handling. A Mossberg-branded ventilated recoil pad with a white-line spacer adds a classic touch. Factory scroll engraving decorates the receiver sides, adding tasteful visual detail without sacrificing function.
