The Mossberg 590S Tactical delivers enhanced capacity and versatility for tactical applications with its unique ability to chamber both 2¾" and 3" shells interchangeably. This pump-action shotgun features an optics-ready receiver cut and maintains the proven reliability that law enforcement agencies depend on worldwide.

What Makes This Different

The 590S platform stands apart from standard Mossberg 590 models through its dual-shell capability and increased capacity. While traditional tactical shotguns require commitment to one shell length, the 590S chambers 2¾" shells for 9+1 capacity or 3" magnum loads for maximum stopping power. The factory optics cut eliminates the need for aftermarket modifications, accepting most red dot sights directly.
