Key Features
- 28″ Vent-Rib Barrel – The vent rib cuts mirage and gives a clear sight plane for fast target acquisition. Why it matters: You need a clean sight picture when swinging on a flushing rooster or crossing clay.
- 3″ Chamber – Accepts 2.75″ and 3″ shells. Why it matters: One gun handles everything from light target loads to heavy waterfowl magnums without a chamber swap.
- Fiber Optic Front Sight – A bright green fiber optic bead grabs light for quick alignment. Why it matters: Low-light conditions at dawn or dusk won’t leave you guessing where the barrel is pointing.
- Removable Choke System (Beretta/Benelli Mobil Thread) – Ships with three chokes (IC, M, F) and a wrench. Why it matters: You can tune the pattern for clays, upland, or waterfowl in seconds without a gunsmith.
- Rubber Recoil Pad & Swivel Studs – Soft pad soaks up recoil; sling studs are factory-installed. Why it matters: More comfort means better follow-up shots, and studs let you add a sling for long walks.
Who It’s For
This shotgun fits the budget-conscious shooter who wants a do-it-all pump for sporting clays, upland hunting, and occasional waterfowl trips. It’s also a solid choice for a first pump gun because the controls are simple and the price leaves room for ammo and gear. If you’re a seasoned hunter looking for a lightweight backup or a dedicated clays gun that won’t hurt to carry, the Cobra III delivers.

FAQ
What choke tubes does the TriStar Cobra III use?
It uses Beretta/Benelli Mobil-thread choke tubes. The shotgun ships with Improved Cylinder, Modified, and Full chokes. You can swap in any aftermarket tube that fits that thread pattern.
Can I shoot steel shot through the factory chokes?
Yes, the included Modified and Full chokes are rated for steel shot. The Improved Cylinder is also fine for steel. Always check choke markings before using steel in any shotgun.
Is the TriStar Cobra III good for left-handed shooters?
The thumb safety is ambidextrous-friendly, but the shell ejection is on the right side. Lefties can still run it, but you’ll get ejected shells crossing your line of sight. A left-handed model is not available.
What is the length of pull on this shotgun?
Per TriStar specs, the length of pull is approximately 14 inches. The rubber recoil pad adds a bit of extra cushion.
