Description
There is a lot to be said for a pump gun that just does its job, and the TriStar Cobra III Field is exactly that kind of shotgun. Chambered for 3" shells in 12 gauge, it will cycle everything from featherweight target loads at the clays course to stout waterfowl shells in the blind. The 28" barrel wears a ventilated rib with a fiber optic front sight, so picking up a flushing rooster or a crossing clay comes naturally, and the chrome lining inside the bore shrugs off the wear and fouling that come with real hunting seasons.
Chokes That Make the Cobra III Earn Its Keep
TriStar ships this gun with three Mobil-pattern choke tubes, Improved Cylinder, Modified, and Full, along with a choke box and wrench. Since the threading matches the widely used Beretta/Benelli Mobil system, finding aftermarket tubes later is about as easy as it gets. Screw in the IC for early season quail, swap to Modified for dove or steel over decoys, and go Full when the shots stretch out. One gun ends up covering a lot of ground.
Built for Long Days in the Field
The Cobra III Field pairs a blued finish with a classic walnut stock and forend, and the extended forearm gives you plenty to hold onto when you are running the action fast. A rubber recoil pad takes the sting out of heavy loads, swivel studs are already in place for a sling, and the thumb-reach manual safety sits right where your trigger hand expects it. Capacity is 5+1, and a magazine plug is included for hunts where you need to limit it.
Why the Cobra III Pump Makes Sense
At around 7 pounds, this gun carries well without beating you up at the bench, and TriStar backs it with a five-year warranty. For a first duck gun, a truck gun that pulls double duty on clays, or a dependable loaner for a new hunter, the Cobra III Field checks the boxes without any fuss.

Frequently Asked Questions
What choke tubes fit the TriStar Cobra III?
The Cobra III uses the Beretta/Benelli Mobil thread pattern, one of the most common choke systems out there. It ships with Improved Cylinder, Modified, and Full tubes plus a wrench and storage box. If you want an extended or specialty tube down the road, any Mobil-pattern choke will thread right in.
Can the Cobra III handle steel shot for waterfowl?
Yes, the 3" chamber and chrome-lined barrel are well suited to steel waterfowl loads. The general rule with steel is to stick with the Improved Cylinder or Modified tubes rather than the Full choke, since steel doesn't compress like lead. Modified over decoys is a solid setup for most duck hunts.
Will the Cobra III cycle light 2 3/4" target loads?
Since it's a pump action, you're the one doing the cycling, so light target loads run just as reliably as heavy magnum shells. That's part of what makes this gun such a good crossover for clays practice and hunting with the same shotgun. Everything from cheap promo loads to 3" waterfowl shells feeds through it.
Does the TriStar Cobra III come with a warranty?
TriStar backs the Cobra III with a five-year manufacturer warranty, which is generous for a pump gun in this class. Their customer service handles support directly if anything ever comes up. Basic cleaning and occasional lubrication are all the routine care it needs.
