Detailed Features 

 
The Steelium Plus barrel is cold-hammer forged from Beretta's proprietary alloy, designed for consistent shot patterns and long service life. The Kick-Off Mega system hydraulically dampens recoil in the stock, which reduces felt impulse on heavy 3" and 3.5" waterfowl loads. The left-hand stock geometry is reversed for proper cheek weld alignment from the left shoulder. The soft comb on the stock reduces face impact during recoil. Five extended chokes (OBF-HOPB) are included. The fiber optic front bead and integral mid bead improve target acquisition in variable light conditions. Chamber accepts 2.75", 3", and 3.5" shells without adjustment. 
 

Usage Scenarios 

• Waterfowl hunting where the Bottomland camo provides concealment in flooded timber and marsh cover 
• Sporting clays and trap shooting where the 28" barrel aids smooth swing 
• Any high-volume session where a left-handed shooter benefits from proper stock fit

The A400 Xtreme Plus KO LH in Mossy Oak draws strong feedback from the group it's designed for: left-handed hunters.

The left-hand configuration is the most-cited reason for purchase. Left-handed shooters have fewer quality semi-auto shotgun options at this level, and the A400 LH addresses that directly.

Reliability is consistently praised. Owners report it cycles 3" and 3.5" waterfowl loads cleanly in cold and wet conditions, which is the primary use case.

The Kick-Off system gets specific credit for making magnum loads manageable over a long hunt. Shooters who've dealt with recoil fatigue from standard gas guns say the difference is real.

The Mossy Oak Bottomland camo is well-matched to late-season hunting environments and gets positive aesthetic and functional comments.

Versatility beyond waterfowl is noted by some. It also handles upland game and clay shooting well.

Negatives: the 7.40 lb weight is a genuine consideration for long-distance carries through dense cover. Price is a recurring concern for buyers comparing it to less expensive alternatives. Some owners report a break-in period before lighter loads cycle reliably. Maintenance requirements for the gas system are also mentioned as something to stay on top of.
