I just bought a monte barrel for my SS and it fits perfectly. Although to be honest, I haven't shot it yet !!!! If you look at the Benelli catalog the monte, legacy, SS, raff, centro, barrels are listed together. They all have the small forearm ring. I can sympathize with you on that 30 inch barrel, its waay to long for most hunting. I went and got a 24 inch barrel and use an extended choke on my SS.
