I have a Mossberg 835 with a long barrel. I do not hunt so my main reason for owning this gun is for a home defense weapon. It was a gift so I did not pick it out for this purpose. I am considering either getting a shorter barrel for it or trading it on 20 gauge with a short barrel. The recoil on it is pretty stout but I can handle it but I would like for my wife to be comfortable shooting it too so I am leaning towards the 20. Any sage advice from the shotgun gurus on here?
