Chambered in 12 gauge with a 3-inch chamber and a heavy-walled 20-inch barrel, this pump-action is built for consistent performance under stress. With a 9-round capacity and a fixed 14.25-inch length of pull, it balances firepower and ergonomics for defensive use.

Design and Durability

Finish and Corrosion Resistance

The standard Parkerized barrel finish offers proven corrosion resistance for field use; Marine models add a Marinecote heavy corrosion-resistant finish for saltwater exposure. The drilled-and-tapped receiver accepts optics or backup sights, while the metal trigger guard and safety provide robust controls that stand up to heavy use.

Stock and Storage Options

The synthetic black stock keeps weight down (7.25 lbs overall) and resists weather. For users who want extra ready ammunition, the optional Plus 4 Shell Storage Stock stores additional shells within the stock itself, accelerating reloads without bulk.

Tactical Features and Sights

Ghost ring sights or twin bead and three-dot options are available to match user preference. The cylinder-bore choke provides consistent patterns for close-range defensive scenarios. The combination of a heavy-walled barrel and a 9-round capacity makes this an effective platform for home defense, law enforcement, or serious training.
