I think Mossberg makes a nice gun, however, I personally cannot stand the rattling pump action. The Binelli Nova has the same problem.

My personal choice is the Reminfton 870 Super Magnum, with a 23" rifle sighted barrel. I prefer the rifle sighted barrel simply because it forces you to keep your head down on the stock to line the sights up, you're not going to shoot high or low; you're going to hit what you aim at downrange. After you sit for 15 or 20 minutes waiting for a turkey to come in, that gun gets awful heavy and it's real easy to peek up over the barrel and shoot high. It won't happen with a properly aligned rifle sight.
