 Another advantage is in the over-bored barrel design, which reduces muzzle jump and also improves shot-patterns.Beretta also redesigned their stock choke system by increasing the length of the choke inside the barrel for a more gradual constriction, without having to add to the length of the barrel like after-market choke tubes do.They then also chose to take the time-proven technology of hydraulic shock absorption from car-manufactures and put it in the gun's stock for up to 44% felt recoil reduction at the shoulder.
