DaveJr. - You have received a great deal of information from the above posts. I will add I love my Rem 1100, 12ga. I bought many years ago, with a fixed choke barrel. I have years later added a rifled barrel, and a barrel with screw in chokes. I felt that if I wanted a one gun for everything this was it, plus it did cut down the recoil when used on Clays.
BUT - because I love firearms I have also added a Pump, S/S and O/O shotguns. They are all UNIQUE in their own way.
You can never have enough firearms.
