TriStar Arms Matrix 20 Gauge 3" 6-Round Semi-Auto Shotgun

The TriStar Arms Matrix 20 Gauge 3" 6-Round Semi-Auto Shotgun delivers reliable semi-automatic performance in a platform purpose-built for tactical, sport, and home-defense applications. Chambered in 20 gauge, this shotgun reduces recoil and muzzle rise compared to 12-gauge alternatives while maintaining adequate knockdown energy for target work and defensive scenarios. The 3-inch chamber acceptance ensures compatibility with modern ammunition loads, and the 6-round semi-automatic design enables rapid follow-up shots without manual operation between rounds.

Built on proven inertia-driven semi-auto mechanics, the Matrix 20 Gauge cycles reliably across a spectrum of load pressures, from light target rounds to full-power 3-inch magnum shells. The 6-round capacity strikes a practical balance between magazine volume and manageable on-gun configuration—critical for tactical operators and sport shooters who prioritize reload speed and retention control. Weighing 8.45 lbs, the shotgun remains mobile and quick-handling in close quarters while maintaining the mass necessary for controllable shot strings. The 37.5-inch overall length and compact profile make it suitable for vehicle storage, breaching operations, and confined-space scenarios common to law enforcement and defensive training.

Law enforcement units, competitive three-gun participants, and home-defense-focused shooters benefit most from the Matrix 20 Gauge's ergonomic balance and soft-shooting platform. Officers and trainers value the 20-gauge recoil signature for extended training cycles and improved shooter sustainability in high-round-count evolutions. Standard 20-gauge ammunition availability remains robust across commercial and duty-rated suppliers, ensuring logistics support for both duty and training environments. The semi-automatic action and 6-round feed system integrate seamlessly with conventional shotgun accessories, including aftermarket slings, mag extensions, and tactical furniture compatible with standard receiver geometry.
