Description
Inertia-driven shotguns have earned their reputation the hard way, in muddy boats and flooded timber, and the TriStar Matrix Inertia puts that same simple operating system in a package that regular hunters can afford. There is no gas piston to gunk up, which means fewer parts to scrub after a long weekend of wet weather and heavy waterfowl loads. The action stays cleaner, the fore-end stays slim, and the whole gun carries at a comfortable weight in the low seven pound range, so it swings quick and totes easy on long walks to the blind.
A Closer Look at the Matrix Inertia 12 Gauge
The 28-inch barrel wears a ventilated rib topped with a fiber optic front sight that pulls your eye right where it needs to be in gray morning light. Both the bore and chamber are chrome lined, a nice touch at this price point that helps shrug off corrosion from steel shot and damp conditions. The 3-inch chamber handles everything from light target loads to stout duck and goose shells, and the threaded muzzle accepts Mobil-pattern chokes, with Improved Cylinder, Modified, and Full tubes included so you are covered from decoying birds to passing shots. TriStar also fitted an oversized bolt handle and bolt release, which you will appreciate the first time you run this gun with cold fingers or gloves on.
Realtree Max-7 Camo, Head to Toe
The synthetic stock and fore-end are dipped in Realtree Max-7 along with the metalwork, so there is no shiny receiver flashing at wary birds overhead. The stock is a fixed field design with a 14.25-inch length of pull that fits most folks straight out of the box, and a crossbolt safety sits right where your trigger finger expects it. Add in a last-round bolt hold open and a light, crisp trigger, and the Matrix Inertia stacks up as a lot of working shotgun for the money. If you have been wanting an inertia gun for waterfowl, upland birds, or the occasional round of clays without spending Italian-import money, this one deserves a hard look.

Frequently Asked Questions
What is the advantage of the inertia action on the TriStar Matrix?
Inertia actions use the gun's recoil to cycle the bolt instead of tapping gas from the barrel, so there is no piston system collecting carbon and powder residue. That means less cleaning, a slimmer fore-end, and reliable cycling even when the gun gets wet or dirty in the blind. It is the same basic operating concept found on shotguns costing two or three times as much.
What choke tubes does the Matrix Inertia use?
The Matrix Inertia is threaded for the Beretta/Benelli Mobil choke pattern, one of the most common systems out there. It ships with Improved Cylinder, Modified, and Full tubes, and aftermarket Mobil-pattern chokes from companies like Carlson's and Briley will thread right in if you want an extended waterfowl or turkey tube.
Can the TriStar Matrix Inertia handle steel shot for waterfowl?
Yes, the barrel and chamber are chrome lined and the 3-inch chamber runs the standard steel duck and goose loads most waterfowlers shoot. Stick with Modified or more open chokes for steel shot at the factory tubes, which is standard practice with any shotgun. The full Realtree Max-7 coverage makes it a natural fit for the marsh.
Will the Matrix Inertia cycle light target loads?
Like most inertia guns, it runs best with loads in the 1 1/8 ounce range and up, and it will happily eat heavy hunting shells all day. Very light promotional target loads can be hit or miss in any inertia shotgun, especially before the action breaks in. Run a few boxes of standard loads through it first and it should settle in nicely.
