I have the Benelli M2. It is just the 3 inch model, but it is cheaper than the SBEII. I don't have the slug barrel, but I love that gun!! I will neverown another brand ofsemi-auto shotguns. I have never had a jam and you don't have to clean it as regularly as you do a gas operated shotgun.

Good Luck with your choice!!!
