I recently purchased a used Nova with 24" barrels and the recoil softening system. The gentleman I purchased it from told me he bought it for use in goose pits where he needed the shorter barrel. My question is, does Benelli have a 28" or 30" barrel available. I have been told at several clubs that they are out there but I haven't seen them in Benelli's catalog. would I benefit from getting this longer barrel ported?
