Overview
The Mossberg 590A1 Pro represents a direct commitment to robust utility and uncompromising reliability in a pump-action shotgun platform. Engineered to meet or exceed military specifications, this 12-gauge variant is designed for sustained, high-stress operational deployment where mechanical integrity and consistent function are paramount. KFF Defense assesses the 590A1 Pro as a definitive choice for demanding applications requiring a duty-grade scattergun.
Key Features
MIL-SPEC Construction
The 590A1 Pro features a heavy-walled barrel, a critical attribute enhancing durability and heat dissipation under rapid firing schedules. Unlike many commercial offerings, this model integrates a metal trigger guard and a metal ambidextrous tang safety, providing superior structural integrity and positive manipulation feedback in adverse conditions. The receiver is precision-machined from aluminum alloy, ensuring consistent component integration and operational longevity.
Corrosion Resistance
This platform is offered with an advanced corrosion-resistant finish, either Marinecote (electroless nickel plating) or a Manganese Phosphate (Parkerized) coating. Both finishes provide a significant increase in environmental resilience compared to standard bluing, crucial for operations in high humidity, marine environments, or extended field deployment. This coating system mitigates the risk of material degradation, maintaining the weapon’s service life.
Operational Ergonomics
The synthetic forend is grooved for a secure, positive grip, optimizing control even when wet or gloved. The synthetic buttstock is designed to provide an optimized length of pull, often incorporating an advanced recoil-absorbing pad to mitigate felt recoil and facilitate sustained operational comfort during extended use. The integrated sighting system, typically a ghost ring rear sight paired with a high-visibility front sight, is calibrated for rapid target acquisition across varied lighting conditions.
Reliability and Capacity
Chambered for 2.75″ and 3″ 12-gauge shells, the 590A1 Pro features a high-capacity tubular magazine, supporting 7+1 rounds of 2.75″ ammunition. This configuration facilitates rapid follow-up shots and extended engagement capability. The robust pump-action mechanism is engineered for reliable cycling across a broad spectrum of ammunition types, from standard birdshot to specialized tactical loads.
