I have two M31's in 12ga, one is a 31-S and the other a 31-H, both with solid rib 30" full choke barrels. They have been death on clay birds and open country dove. I also have a M31 standard in 16ga. It hasn't received a whole lot of play as I have had my 16ga M12 longer and gravitate to it whenever the need arises.
My Dad had a M31 solid rib skeet that I sold for some new fangled mess when I was young and stupid. This model will always have a special place in my heart that no 870 will ever fill.
