Just took out my new shotgun this weekend for opening grouse, worked great. But, my father-in-law looked at my gun and he thinks the stock or butt or maybe both are set up for a left handed shooter. Now I shoot right handed so this bothered me...until I shot really well this weekend.

So, 1) does anyone know how I could tell if my Beretta is set up for lefties and 2) does it really matter?
