RE: Beretta vs. Bennelli
Between my dad and I we have three 391Urika' s and love them. Sweetest shooting autoloader that I' ve ever shot. Geese, ducks, and Pheasant. No problems with jamming on 2 3/4 or 3 inch shells. I haven' t tried the Xtrema. I' m going to guess that a main difference between the two is recoil as the Beneli isn' t gas operated. One item that you may or may not know is that Berreta is the parent company for Beneli and they make all of the beneli barrels. I' m not sure if this helps or not.
