I would have to vote for the Nova too, last year my 870 actually
froze-up on me. When the freezing rain turned to snow I could not
get it to pump! I bought a nova the next day one heck of a
duck & goose gun. I have an old Rem. model 31-A built before
the 870 30" full choke and it still will shoot the pants off the newer
870's. But you need to take into consideration what you will be
hunting, and in what conditions you will be hunting. But I still
love the Nova.
