Why don't you get what I have? I have a 20ga Remington 870 Express Magnum. Has a magnum reciever, and will shoot 3in rounds, if needed. This is a full size gun. Not too bad of a handler with the 26in bird barrel on it, but I bought a 21in deer barrel with rifle sights. WOW! Talk about quick. I plan on getting a magazine extention when I get some extra money. Bushmaster's website has them.
You can buy synthetic stocks for them, I think. The wood works fine for me. You also have the capability to change the round in the chamber while keeping a full magazine, I just figured out how to do this yesterday. The only complaint I have with this gun is that it rusts easily. Forget RemOil. Use CLP or something heavier on the reciever. One plus is that you can get one for around $225, and at that price, I drag it around in the mud and brush deer hunting without tears
