RE: Which semi 12 x 3 1/2"
I would have to disagree with all this totally anti 3.5" sentiment that is going on here. I made the switch and found that hitting geese came much easier. There were far fewer flutter and flies than I had with the 3" and that is important. I feel that the Super X is a great gun. I researched extensively and came to that decision. It is not terribly heavy, it shoots lighter loads, and it is less expensive than all the other big name magnum autos. It is a great all purpose shotgun and can do a lot of things with the right choke and load.
