Design and Mil-Spec Provenance

This shotgun is the only model to pass the MilSpec 3443E trial that required 3,000 consecutive rounds fired without jamming. That certification underlines the platform’s durability. The 590A1 features a Parkerized finish on standard models and a Marinecote heavy corrosion-resistant finish on Marine configurations, giving you long-term protection in harsh environments.

Key Specifications and On-Gun Benefits

Caliber, Capacity, and Chamber

Chambered in 12 gauge with a 3″ chamber and a standard 9-round capacity, the 590A1 balances stopping power with magazine capacity for defensive applications. The cylinder bore choke and available barrel lengths—18.5″ or 20″—make it suitable for close-quarters engagements and duty use alike.

Controls, Sights, and Ergonomics

The metal trigger guard and safety provide positive tactile feedback under gloves. A drilled-and-tapped receiver accepts optics for operators who prefer red dots, while ghost ring sights, twin bead, and three-dot options are available for fast, instinctive sighting. Length of pull is a fixed 14.25″ to maintain consistent handling; overall weight is approximately 7.25 lb.

Modularity and Optional Accessories

Options include the synthetic Plus 4 Shell Storage Stock that adds onboard capacity without compromising sling or grip ergonomics. The synthetic Black-SpeedFeed stock offers weather-resistant performance for daily carry or maritime duty. At a listed price of $744.99, the platform delivers MilSpec reliability without premium collectable markup.
