Description
Finding a pump gun that fits a smaller frame without feeling like a toy is harder than it should be. The TriStar Cobra III Compact gets it right. It takes the proven Cobra III Field platform and trims the stock down to a 13 inch length of pull, then pairs it with a 24 inch vent rib barrel so the whole package stays light, balanced, and easy to swing. For a young hunter working their first dove field or an adult who just prefers a shorter gun in tight cover, the fit is the whole story here, and this one nails it.
A 20 Gauge Cobra III That Grows With the Hunter
The 3 inch chamber is what makes this gun more than a starter shotgun. Run light 2 3/4 inch target loads for clays and practice sessions, then step up to 3 inch magnum loads when turkey or waterfowl season rolls around. The removable choke system uses Beretta and Benelli Mobil threads, one of the most common patterns out there, and TriStar includes Improved Cylinder, Modified, and Full tubes along with a choke box and wrench. The chrome lined barrel and chamber shrug off the wear that comes with steel shot and wet mornings.
Field-Ready Details on the Cobra III Compact
A fiber optic front sight sits on the matted vent rib and picks up light fast when a bird flushes. The extended forearm gives smaller hands plenty of real estate to run the action, which cycles smoothly right out of the box. A rubber recoil pad takes the edge off heavier loads, and sling swivel studs come installed so adding a sling for the walk in takes minutes. The walnut stock and black metalwork give it a classic field look that punches above its class.
Why the Cobra III Compact Earns a Spot in the Safe
With 5+1 capacity, a removable shot plug for migratory bird hunting, and TriStar's five year warranty behind it, this is a working shotgun built to be carried and used. It is the kind of gun that starts as a first shotgun and sticks around because it keeps doing its job.

Frequently Asked Questions
Is the TriStar Cobra III Compact a good first shotgun for a young hunter?
It is one of the better options in its class for exactly that. The 13 inch length of pull fits smaller frames properly, the 24 inch barrel keeps the gun light and easy to swing, and 20 gauge recoil with the rubber recoil pad is manageable for new hunters. The 3 inch chamber also means the gun stays useful as they grow into heavier hunting loads.
What choke tubes work with the Cobra III Compact?
It uses the Beretta/Benelli Mobil thread pattern, which is one of the most widely available choke systems on the market. TriStar includes Improved Cylinder, Modified, and Full tubes with a box and wrench, so you are covered for most hunting and clays work right out of the box. Aftermarket Mobil chokes from brands like Carlson's and Briley drop right in.
Can the Cobra III Compact shoot both 2 3/4 and 3 inch shells?
Yes. The 3 inch chamber handles everything from light 2 3/4 inch target loads up to 3 inch magnum hunting loads. That range makes it a legitimate do-it-all gun for clays, dove, turkey, and waterfowl. The chrome lined barrel and chamber also hold up well to steel shot.
How many rounds does the TriStar Cobra III Compact hold?
It holds 5 rounds in the magazine tube plus one in the chamber for 5+1 total capacity. A removable shot plug comes installed to limit capacity for migratory bird hunting, and it pulls out quickly when you want the full tube. That flexibility is handy if the gun pulls double duty between seasons.
