Mossberg is a good gun for the money. I just love the feel and trust the absolute reliability of the Remington 870. We had them in the AF and I never ever saw one fail (as an instructor, often with completely inexperienced shooters) even thought they were older than dirt and beat to death. There were Ithacas and Wins, also, but they didn't fare as well. We had 'em at the Corrections Dept. where I was also an instructor -- same story. I kept one in my patrol car as a police officer and I'm embarrassed at the lack of care it got. It never failed.
I'm not saying the Mossberg or Winchester won't do the same. I'm saying what the Remington did for me. I do like the Benelli and saw an FBI guy at an NRA Instructor class make one sing. But that's the FBI's budget compared to mine.
