The TriStar Cobra III Marine delivers reliable performance in harsh conditions with its corrosion-resistant marine finish and proven pump-action design. This 12-gauge shotgun combines the durability needed for marine environments with the versatility required for tactical applications and home defense.

What Makes This Different

The marine-grade coating sets this shotgun apart from standard models, providing enhanced protection against saltwater corrosion and moisture damage. The silver receiver and barrel finish undergoes specialized treatment that exceeds standard bluing or parkerizing for longevity in coastal and humid environments. The 18.5-inch barrel length meets federal requirements while maintaining maneuverability in confined spaces.

Field testing demonstrates consistent cycling with both 2.75-inch and 3-inch shells across various load weights.

Law enforcement agencies have adopted similar configurations for patrol vehicle storage due to the compact profile and weather resistance.
