Description
The Beretta A400 Xplor Action in 20 gauge with a 28 inch barrel and the Kick-Off stock, part number J40AY28, is the most comfortable gun in the Xplor line for anyone who shoots open country. The longer barrel steadies the swing on crossing birds, and the hydraulic stock means you can shoot a box of shells without the day catching up with your shoulder.
Chamber is 3 inches, capacity is four plus one, the barrel is blued with a ventilated rib, and the walnut Kick-Off stock sits behind a bronze anodized aluminum receiver.
Length where you need it, recoil where you do not
Light guns are easy to start and easy to stop, and stopping the gun is the most common reason a shooter misses a crossing bird. Two inches of barrel over the 26 inch build add enough forward weight to carry the swing, and lengthen the sighting plane at the same time. On a field edge or over decoys, that steadiness is what puts birds down.
Kick-Off deals with the other end. Hydraulic dampers inside the buttstock stretch the recoil impulse across a longer interval instead of delivering it as one sharp shove. Combined with a 20 gauge bore and a gas action, there is almost nothing left to notice, and shooters who have been avoiding 3 inch loads can use them without hesitation.
Blink gas system and the fittings
Blink is the gas system Beretta uses in its competition guns: fast cycling, a self-cleaning piston, and pressure venting so light 2 3/4 inch target loads and 3 inch hunting shells both run without adjustment. On a light gun the gas action is doing real work on recoil before the Kick-Off dampers ever engage.
The bronze anodized aluminum alloy receiver keeps the carry weight down and gives the gun its look. A walnut stock with a checkered forend, a chrome-plated trigger, a two-position crossbolt safety, Optima HP choke tubes, and a fiber optic front sight finish it.

Why it is worth considering
- Barrel length that keeps a light gun’s swing honest on crossing birds.
- Hydraulic recoil dampers on top of a small bore and a gas action.
- Still light enough to carry all day on an aluminum alloy receiver.
- Runs 3 inch loads comfortably, which a 20 gauge without the stock does not always do.
- A fiber optic front sight for dawn and dusk.
Who it suits
This is the open-country 20 gauge for a shooter who values comfort: doves over cut fields, pheasants on field edges, and decoying ducks with 3 inch loads. It is also the gun to hand a younger or smaller shooter who is ready to move up from a youth model but should not be learning to flinch. Hunters in thick cover will be quicker with the 26 inch build, and anyone who needs more payload for long shots in the open should be looking at a 12 gauge.

Shells, chokes, and transfer notes
Shotshell dimensions and pressures are standardized by SAAMI, and the 3 inch chamber accepts both 2 3/4 and 3 inch 20 gauge shells. We stock 1 ounce number 5 pheasant loads for hunting and 7/8 ounce 7.5 shot for practice. Steel shot is safe through improved cylinder and modified Optima HP tubes but not a full choke, and waterfowlers should confirm state non-toxic rules before opening day.
Hunters in thick cover should compare the 26 inch Kick-Off build, and anyone who does not need the hydraulic stock can look at the standard 28 inch 20 gauge. Every long gun we sell ships to a licensed FFL for transfer and background check, and Pennsylvania buyers should plan on the state point of contact check at pickup.
