Detailed Features 

 
The Steelium Plus barrel is cold-hammer forged and delivers consistent shot patterns. The Kick-Off Mega hydraulic buffer system reduces felt recoil substantially, which translates to faster recovery between shots. The Optima Bore HP choke system includes five tubes (F, IM, M, IC, C). The chrome-plated trigger resists corrosion. All controls are configured for left-handed operation. The dark gray Cerakote finish on the receiver is more corrosion-resistant than standard blued steel. 
 

Usage Scenarios 

The left-hand orientation makes this a practical choice for left-handed waterfowl hunters who have struggled with converted or ambidextrous designs. The 3.5" chamber handles all 12-gauge loads including high-brass steel shot. The Kick-Off Mega system and the 7.40 lb weight combine to make heavy loads shootable for extended sessions.

The Beretta A400 Xtreme Plus KO LH 12GA gets good marks from left-handed shooters who appreciate having a dedicated left-hand configuration rather than a modified right-hand design. The precision and consistency of the Steelium Plus barrel are frequently cited. The Kick-Off system for recoil reduction is a consistent positive across all A400 Xtreme Plus variants.

Build quality gets strong praise. Versatility with light through heavy loads is a noted strength.

The weight of 7.40 lbs comes up as a drawback for some who prefer lighter guns for long carries. Price is higher than many competitors, which is acknowledged even by satisfied owners. A small number of users mention a learning curve for those new to semi-auto operation from pump-action platforms.
