TriStar Matrix Inertia 12 Gauge 28" 5+1 Semi-Auto Shotgun

The TriStar Matrix is an inertia-driven semi-automatic shotgun built around a 3-inch chamber and chambered in 12 Gauge. This full-size configuration pairs a 28-inch black vent-rib barrel with a black steel receiver and a fixed walnut stock, giving the Matrix a classic field look aimed at upland, clay, and general-purpose shotgunning.

TriStar arms the Matrix with a clean crossbolt safety positioned behind the trigger and a bright fiber-optic front sight for fast target acquisition in low light. The 28-inch barrel is threaded for the widely available Beretta/Benelli Mobil choke system and ships with three chokes included: Full, Improved Cylinder, and Modified, so the gun can be set up for tight patterns at distance or wider coverage on flushing birds.

Designed for right-hand shooters, the Matrix measures 49 inches overall and tips the scales at 7.10 lbs. The walnut stock carries a brown finish and a fixed comb, while the matte-black barrel and receiver complete the understated field-ready look. Capacity is rated at 5+1 rounds of 2-3/4" or 3" 12-gauge shells in the tubular magazine.

The inertia-action design delivers reliable semi-auto cycling at a budget-friendly price point, making the Matrix a sensible choice for hunters and clay shooters who want a dependable semi-auto without stepping up to premium-tier pricing.
