The A400 Xtreme Plus semi-auto shotgun features Beretta's exclusive Steelium Plus barrels, a first for hunting shotguns providing the best patterning possible from all hunting loads, along with further felt recoil mitigation. Further drawing from the competition world, the A400 Xtreme Plus barrel features a step rib with an integral mid-bead and fiber optic front bead in order to ensure the proper fit and sight picture for all conditions. Further enhancing the A400 Xtreme Plus is the addition of an extended charging handle and bolt release from the factory to allow for easier manipulation during the coldest and rainiest days, as well as an enlarged loading port to allow for easier loading in adverse conditions.
