DeeZee,
Both are great guns. My 500 started out as a pistol grip gun. Mossberg sold these a while back. I think I paid ~180.00 for it out the door. One thing you dont want is a pistol grip 12 ga I put some cheap folding stock on it, cant remember the name, and it shot way high @ 25 yrds. It now has a Speedfeed pistol grip stock on it and is my general house defense gun. The one thing I dont like about the Mossberg is the safety location on top/rear of the receiver. The Remmy is better located for me on the trigger guard.
I bought the 870 express mag. with some competition 3-gunning in mind but havent shot it alot but works fine.
