Description
The Beretta A400 XTR Plus KO 12 GA with a 28-inch barrel and 3.5-inch chamber is a semi-automatic shotgun built for the serious waterfowl and upland hunter who demands reliability in wet, muddy conditions. Whether you are working a flooded timber hole in Arkansas or chasing pheasants across a Dakota stubble field, this platform is engineered to cycle quickly and consistently with heavy magnum loads or lighter field shells. It is a tool designed for long days in the field, not for the gun safe.
What This Product Is and Who It Is For
The Beretta A400 XTR Plus KO is a gas-operated semi-automatic shotgun chambered in 12 gauge, with a 3.5-inch chamber that allows you to shoot everything from 2.75-inch target loads to the heaviest 3.5-inch waterfowl magnums. It is built for the hunter who spends time in harsh environments—salt marshes, rain-soaked fields, and icy blinds. This is not a home defense shotgun or a concealed carry firearm; it is a dedicated hunting platform. It is suited for the waterfowler who needs a gun that sheds mud and moisture, for the upland hunter who walks miles with a balanced, fast-handling shotgun, and for the shooter who wants a reliable semi-auto that reduces felt recoil without sacrificing cycling speed.

Feature Deep-Dive
The Beretta A400 XTR Plus KO uses the company’s proprietary Kick-Off Mega recoil reduction system, which is housed in the stock. This system uses a hydraulic damper and sliding buttpad to reduce felt recoil by up to 40 percent compared to standard shotguns. For a hunter shooting heavy 3.5-inch loads, this translates to less shoulder fatigue during a long day of shooting and faster follow-up shots. The system is adjustable to fit your body mechanics, and it does not add noticeable weight to the overall package.
The Aquatech Grey finish on the receiver is not just cosmetic. It is a corrosion-resistant coating applied to the aluminum alloy receiver, and it is paired with a True Timber Dirt camouflage pattern on the barrel and stock. This combination is designed to withstand prolonged exposure to moisture, mud, and saltwater without rusting or degrading. The barrel is chrome-lined for additional durability and easier cleaning, which is critical when you are running high-volume hunts in wet conditions.
Beretta’s patented self-cleaning piston system is a standout feature on this model. Unlike traditional gas systems that require frequent disassembly and cleaning to maintain reliability, this piston automatically clears carbon fouling with each shot. This means you can fire hundreds of rounds between cleanings without experiencing malfunctions. For the hunter who does not want to break down a shotgun in a muddy blind, this is a practical advantage that keeps the gun running when conditions are less than ideal.
The 28-inch barrel with the Optima-Bore HP choke system provides a balanced swing and consistent pattern density. The barrel is back-bored to reduce felt recoil and improve pattern uniformity, and the interchangeable choke tubes allow you to fine-tune your shot spread for decoying ducks, pass-shooting geese, or flushing pheasants. The red bar front sight is simple and fast to acquire, even in low-light conditions at dawn or dusk, without being overly bulky or prone to snagging on brush.
The synthetic stock is designed for durability and weather resistance, with a textured grip surface that remains secure even when wet or gloved. The stock includes a shim system that allows you to adjust cast and drop to fit your shooting stance, which can improve mount consistency and accuracy. The forend is similarly textured and features a subtle palm swell that encourages a natural hand position for smooth swinging.
Reliability in extreme temperatures is a hallmark of the A400 action. The gas system is tuned to cycle a wide range of ammunition, from light 1-ounce target loads to heavy 3.5-inch magnums, without manual adjustment. This is achieved through a self-regulating valve that adjusts gas pressure based on the shell being fired. The bolt carrier is coated with a low-friction finish that reduces wear and ensures smooth operation even when the action is cold or dirty.
Ideal Use Cases
This shotgun is designed primarily for waterfowl hunting, including duck and goose hunting in marshes, flooded timber, and open water. The 3.5-inch chamber and Aquatech finish make it a strong choice for hunters who routinely work in wet environments. It is also well-suited for upland hunting, such as pheasant, quail, and grouse, where the 28-inch barrel offers a good balance of swing speed and reach. The reduced recoil system makes it a viable option for shooters who are sensitive to heavy loads or who plan to shoot frequently during the season. This is not a concealed carry or home defense firearm; it is a dedicated hunting tool for the field.
Compatibility Notes
The Beretta A400 XTR Plus KO accepts all standard 12-gauge shells with a shell length of 2.75 inches, 3 inches, or 3.5 inches. It uses Beretta Optima-Bore HP choke tubes, which are widely available in a variety of constrictions. The gun is compatible with most aftermarket accessories designed for the A400 platform, including extended magazine tubes (where legal), sling swivel studs, and recoil pads. Holsters are not applicable to this firearm. Magazines are limited to the factory tube magazine; aftermarket extensions are available for increased capacity in jurisdictions that allow them. The stock accepts standard Beretta spacers and shims for fit adjustment.
