I looked at both and went with the Nova, I now know 7 people with them and none of them have any complaints. The only complaint I had was the forearm rattle. I tightened the two allen screws and it took most of it out. I would recomend the Nova it is a great gun. I shoot 3.5" shells through it all duck and goose season. It has a lot more features than the 870 too.
