The Mossberg 590S Shockwave is a compact 12 Gauge pump-action firearm built around the proven 590 platform. Its 14.375-inch heavy-walled cylinder-bore barrel and Raptor bird's head grip provide a maneuverable configuration, while the corn-cob forend with hand strap helps maintain control during operation. The three-inch chamber accepts 1 3/4 inch, 2 3/4 inch, and 3 inch shells in mixed combinations. Capacity is 8+1 with 1 3/4 inch shells, 5+1 with 2 3/4 inch shells, or 4+1 with 3 inch shells. A top-mounted manual safety, bead front sight, dual extractors, twin action bars, positive steel-to-steel lockup, and anti-jam elevator support dependable handling and smooth cycling.
The Mossberg 590S Shockwave combines flexible shell compatibility with a compact, controllable pump-action design for range and defensive applications.
