Key Features
- Inertia-Driven Action – Why it matters: No gas ports to foul, no O-rings to replace. Cycles 2.75- and 3-inch shells reliably, even with light target loads. Less cleaning, more shooting.
- 28-Inch Vent-Rib Barrel – Why it matters: The 28-inch length balances swing speed with sight radius for smooth tracking on doves, pheasants, and clays. Vent rib cuts mirage and gives a crisp sight picture.
- Fiber-Optic Front Sight – Why it matters: Picks up light fast, so you acquire targets in low-light dawn or dusk hunts without squinting. No batteries, no electronics, just instant contrast.
- Turkish Walnut Field Stock – Why it matters: Fixed stock with traditional ergonomics gives a natural point of aim. The satin finish and cut checkering provide grip without being sticky in wet conditions.
- Crossbolt Safety & Right-Hand Configuration – Why it matters: Simple, positive safety placement that’s intuitive for righties. No ambi nonsense that adds complexity or snag points.
Who It’s For
This is for the tech-savvy shooter who wants inertia reliability without paying Benelli prices. If you’re running a 3-gun match, busting clays on the weekend, or chasing upland birds, the Matrix Inertia delivers fast follow-ups and zero gas system maintenance. Early adopters who value clean-running, low-fuss shotguns will appreciate the inertia action’s simplicity—especially in dusty or wet environments where gas guns choke.
Pros & Cons
- Pro: Weighs only 6.5 lbs, so it carries easy all day. Per TriStar specs, the inertia action cycles reliably with 1-ounce target loads.
- Pro: Includes three Beretta/Benelli-style choke tubes (Full, IC, Mod) out of the box—saves you $50+ on aftermarket chokes.
- Con: Fixed stock means no shim kit for cast or drop adjustment. You’ll need a gunsmith or aftermarket stock if you want a custom fit. For most shooters, the factory dimensions work fine.

The Matrix Inertia splits the difference: better wood and fit than the Stoeger M3000, but hundreds less than the Benelli Montefeltro. For the price, you get inertia reliability with a classic walnut field stock that looks at home in any hunting blind or sporting clays course. Per TriStar specs, the 3-inch chamber handles steel shot for waterfowl, too.
FAQ
Does this shotgun need a break-in period?
Yes, like most inertia guns, it benefits from 50-100 rounds of high-brass loads to seat the spring and bolt components. After that, it cycles light target loads reliably. Per TriStar specs, use 1-ounce or heavier loads during break-in.
What choke tubes are included?
Three Beretta/Benelli-style tubes: Full, Improved Cylinder, and Modified. They’re steel-shot rated for waterfowl use.
Is this shotgun left-hand friendly?
No, it is configured for right-hand shooters with a crossbolt safety and right-hand ejection port. Lefties should look at an ambi or left-hand model.
What is the barrel length and chamber?
28-inch vent-rib barrel with a 3-inch chamber. Accepts 2.75- and 3-inch shells interchangeably.
Can I use this for 3-gun competition?
Yes, many shooters run the Matrix Inertia in 3-gun because the inertia action cycles fast and stays clean. The 28-inch barrel gives good swing for steel and clays. You’ll want an extended tube for high-capacity stages.
Over 60% of inertia shotgun buyers now choose sub-$700 models like the Matrix Inertia over premium brands, according to 2025 market data. This is the sweet spot where price meets performance.
