Debello

I am looking to purchase an extra Benelli R1 338 magazine, but they seem to be not listed in any Benelli catalog so their resellers are unable to order it. When I spoke to Benelli customer support they will only provide a warranty replacement and not sale one directly to me. Does anyone know where to purchase magazine at, as I do not like having only one magazine when I am out because I don't want an entire trip to be ruined by a broken or faulty magazine.
