Description
There is a lot to like about a 20 gauge pump that does not overcomplicate things, and the TriStar Cobra III Field is exactly that kind of gun. It runs a 3 inch chamber, so you can feed it anything from featherweight target loads for a casual afternoon of clays to stout waterfowl and turkey loads when the season opens. The 26 inch barrel wears a vent rib with a matted sight plane and a fiber optic front sight that grabs your eye fast, even in the gray light of early morning. Both the barrel and chamber are chrome lined, which means easier cleanup and better resistance to the wet, muddy conditions hunting guns tend to live in.
Built for the Field in Realtree Max-7
This version of the Cobra III comes dipped head to toe in Realtree Max-7, a pattern designed to disappear in marsh grass, cattails, flooded timber, and open ag fields alike. The synthetic stock shrugs off rain and rough handling, a soft rubber recoil pad takes the sting out of heavier loads, and sling swivel studs come standard so you can add a sling for those long walks in. TriStar also gave this pump an extended forend, which fills the hand nicely and makes cycling the action feel natural whether you are wearing gloves or not.
Chokes, Capacity, and Everyday Versatility
The Cobra III uses the Beretta/Benelli Mobil choke thread pattern, one of the most common systems out there, and ships with improved cylinder, modified, and full tubes plus a wrench. That covers close flushing birds, decoying ducks, and longer pokes without buying anything extra, and aftermarket tubes are easy to find if you want to fine tune your pattern. Capacity is 5+1 with 2 3/4 inch shells, and a removable shot plug is included for when regulations call for three rounds in the gun. Add in the softer recoil and lighter carry weight of a 20 gauge, and this is a smart pick for new hunters, smaller framed folks, or anyone who wants one dependable pump that can wear a lot of hats.

Frequently Asked Questions
Can the TriStar Cobra III 20 gauge handle 3 inch shells?
Yes, it has a 3 inch chamber, so it runs both 2 3/4 inch and 3 inch shells. That gives you the flexibility to shoot light target loads at the range and step up to magnum waterfowl or turkey loads when it counts. The chrome-lined chamber and barrel also help with steel shot and wet-weather durability.
What choke tubes does the Cobra III use?
It uses the Beretta/Benelli Mobil thread pattern, which is one of the most widely supported choke systems around. Improved cylinder, modified, and full tubes come in the box along with a wrench, so you are covered for most hunting and clays work without spending another dime. If you want a specialty turkey or extended waterfowl tube later, aftermarket options are plentiful.
Does this shotgun come with a plug for hunting?
It does. The Cobra III ships with a removable shot plug that limits the magazine for migratory bird hunting, and TriStar designed it for quick removal when you want the full 5+1 capacity back. It is a nice touch that saves you a trip to the parts counter before opening day.
Is the TriStar Cobra III a good gun for a newer shotgun hunter?
It is a strong choice. The 20 gauge kicks noticeably less than a 12, the rubber recoil pad softens things further, and pump actions are about as simple and reliable as shotguns get. Add the included chokes, fiber optic front sight, and weatherproof synthetic stock, and it is an easy gun to learn on and grow with.
