Which model?
This is from the Benelli USA site.
"Rifled slug barrels are available for Super Black Eagle, Super Black Eagle II, M1 Field, M2 Field, SuperNova and Nova models only. (For SBE, SBEII, M1 and M2 models, slug barrels require a modified fore-end sold separately)."
Epp's is a Benelli dealer. Contact them. They'll tell you if they can get one for you. You'll be digging deep for it though. Benelli barrels aren't cheap.
