there are 2 pump shotguns that all others are judged by. The Remington 870 and the winchester model 12.
In my eyes all other pump shotguns are just trying to be one of them two if not both.
Don't get me wrong the Nova and teh mossy 500 are great shot guns.
You may want to look at the stoeger model 2000
it cost around $400 and is really a Benelli in different cloths.
