Key Features
- Inertia-Driven Action – Why it matters: No gas system to clean or foul, so you spend more time shooting and less time scrubbing. It cycles clean and reliable, even in dusty dove fields.
- 26-Inch Vent Rib Barrel – Why it matters: That extra sight plane and the ventilated rib cut down heat mirage, helping you stay on target when birds are crossing fast.
- Fixed Turkish Walnut Stock – Why it matters: A proper field stock with a classic profile that points naturally. The wood is dense and well-figured, not some cheap laminate.
- Fiber-Optic Front Sight – Why it matters: Picks up light fast, so you see that bead against a gray sky or green timber. No fiddling with beads that disappear.
- 5+1 Capacity – Why it matters: Enough rounds for a limit of quail or a string of clays before you have to reload. Keeps you in the action longer.
Who It’s For
This shotgun is built for the Southern bird hunter who values a lightweight, fast-swinging 20 gauge for dove, quail, and woodcock. It’s also a fine choice for the sporting clays shooter who wants a gun that doesn’t beat you up after a hundred rounds. If you appreciate walnut and blued steel over plastic and camo, this one speaks your language.
Pros & Cons
- Pro: Inertia action means less recoil than a gas gun and near-zero maintenance.
- Pro: The walnut stock is a cut above synthetic stocks in looks and feel.
- Con: Some shooters find inertia guns need a firm shoulder mount to cycle light target loads reliably. Per TriStar Arms specs, the gun is designed for field loads, so you may want to test with 1-oz or heavier shells first.
- Pro: At 6.2 lbs, it’s a pleasure to carry all day.
- Con: No adjustable comb or shims for cast—it’s a fixed stock, so if you need a custom fit, you’ll have to visit a gunsmith.

FAQ
What shells does the TriStar Matrix Inertia 20 gauge cycle reliably?
It cycles most 2.75″ and 3″ field loads from 1 oz to 1.25 oz. Light target loads (7/8 oz) may not cycle consistently due to the inertia system. Per TriStar, breaking in with a few boxes of heavy loads helps.
Can I use this shotgun for waterfowl?
Yes, with the 3″ chamber you can shoot steel shot for ducks and geese. Just make sure to use non-toxic shot and pattern your gun first. The blued finish will hold up fine with proper care.
Is the stock adjustable for length of pull?
No, the stock is fixed. But you can add a slip-on recoil pad to shorten length of pull or increase it with a spacer kit from a gunsmith.
How do I clean the inertia system?
It’s simple. Field strip the gun, wipe the inertia spring and bolt assembly clean, then lightly oil. No gas ports to scrub. That’s one reason inertia guns are popular with dove hunters.
