The Beretta A400 Xplor Action KO is a semi-automatic shotgun with a 26-inch barrel chambered in 12 GA (3"). The walnut stock and bronze-toned aluminum receiver give it a distinctive look, and the fiber optic bead front sight holds up well in low-light conditions.

Detailed Features 

 
The Optima-Choke HP system ships with three chokes (C, F, M), so you can adjust shot patterns for different targets. Beretta's Kick-Off system in the fixed stock noticeably cuts felt recoil, which helps with quick follow-up shots and matters during long sessions. At 7.80 lbs the gun is easy to swing without feeling light to the point of amplifying recoil. The bronze-toned aluminum receiver resists corrosion and wear well. For aiming, the fiber optic front bead works reliably when light gets flat.

The A400 Xplor KO draws consistently positive feedback. Shooters frequently point to the smooth cycling and the Kick-Off system as the main reasons they bought it, particularly those who shoot a lot of rounds in a single outing or who are sensitive to recoil. The build quality and materials get high marks, and the gun's looks come up often in a good way.

On the practical side, the A400 handles a wide range of loads without fuss, which owners hunting birds or shooting clays both appreciate.

The most common criticism is the price -- it sits higher than many semi-auto competitors. A smaller number of users found disassembly more involved than expected, though most don't have trouble once they're familiar with it.
