Key Features
- Steelium Plus Barrel: Why it matters — This barrel is cryogenically treated and honed to a mirror finish, giving you the best possible pattern density from light target loads to heavy magnum waterfowl shells. You’ll see tighter, more consistent shot strings at longer ranges.
- Kick-Off KO Recoil Reduction System: Why it matters — It uses hydraulic dampeners to absorb up to 40% of felt recoil, so youth shooters and smaller-framed family members can shoot all day without flinching or fatigue.
- Extended Charging Handle and Bolt Release: Why it matters — Larger, easier-to-grip controls let you load, unload, and clear malfunctions quickly with gloved hands or in low light. Perfect for early-morning duck blinds or late-afternoon dove fields.
- Step Rib with Fiber Optic Front Bead and Mid-Bead: Why it matters — The step rib gives a clear, repeatable sight picture, and the fiber optic front bead glows in low light. The mid-bead helps you maintain proper cheek weld and head position for consistent hits.
- Drilled & Tapped Receiver: Why it matters — You can easily mount a red dot or low-profile scope without sending the gun to a gunsmith. This opens up the shotgun for turkey hunting or slug use with optics.
Who It’s For
This shotgun is built for the family that hunts together. Whether you’re teaching a teenager to shoot their first duck, chasing pheasants in thick cover, or running a 20-gauge in a sporting clays league, the A400 Xtreme Plus KO handles light loads and heavy 3″ shells without complaint. The Kick-Off system makes it an excellent choice for anyone who wants to shoot more with less punishment.
Pros and Cons
- Pros: Extremely soft recoil, excellent pattern consistency with Steelium Plus barrel, easy-to-use extended controls, reliable cycling with 2.75″ and 3″ shells, drilled and tapped for optics.
- Cons: At 6.7 lbs, it’s slightly heavier than some dedicated upland 20-gauges. The OD Green stock may not appeal to traditional wood-stock fans.

The Beretta A400 Xtreme Plus KO offers the best recoil reduction and barrel performance in its class, but the Benelli M2 is lighter for fast swingers. The Remington 870 is the budget-friendly pump option.
FAQ
What shells does the Beretta J42XG28 cycle reliably?
It cycles 2.75″ and 3″ 20-gauge shells reliably, from light 7/8 oz target loads to heavy 1 oz waterfowl loads. The self-cleaning piston system handles dirty shells well.
Can I mount a red dot on this shotgun?
Yes. The receiver is drilled and tapped for a scope base or red dot mount. We recommend a low-profile Picatinny rail (sold separately) for most optics.
Is the Kick-Off system adjustable?
No, but it is pre-set at the factory to provide maximum recoil reduction for standard hunting loads. It does not require adjustment or maintenance.
Does this shotgun come with choke tubes?
Yes, it includes a set of Beretta’s Optima-Choke HP tubes (IC, M, F). You can swap them for aftermarket options to fine-tune patterns.
Is this model suitable for left-handed shooters?
This model is a right-hand configuration (right-handed stock and ejection). Left-handed shooters should look for the A400 Xtreme Plus KO left-hand version.
