Detailed Features 

 
The Kick-Off MEGA recoil reduction system runs a hydraulic damper in the stock, cutting felt recoil enough that shooters can maintain a better shooting position through longer strings. The Steelium Plus barrel is cold-hammer forged from Beretta's proprietary alloy and is designed for consistent shot patterns. The five extended choke tubes (F, IM, M, IC, C) cover everything from tight turkey patterns to wide cylinder-bore spreads, making this gun usable across different hunting and clay applications without separate purchases. 
 

Usage Scenarios 

• Field hunting where load compatibility matters (2.75" through 3.5") 
• Sporting clays and trap shooting with the 26" barrel 
• Any application where reduced recoil over a long day is a priority

The A400 Xtreme Plus draws consistently positive feedback from serious hunters and clay shooters.

Reliability across a wide range of ammunition types is the most common praise. Users report it cycles light loads and heavy magnums without changes to the gas system.

The 26" barrel is frequently mentioned as a good balance between field maneuverability and swing-through accuracy, especially for birds.

The gas-operated system and adjustable stock shims get credit for making the gun comfortable to shoot over extended sessions. Stock adjustability in particular helps shooters get a proper fit.

The downsides center on price -- it sits at the higher end of semi-auto shotguns, and some buyers debate whether the feature set justifies the cost over less expensive options. A small number of users mention aesthetic preferences for different finish options.
