I just got my contender at a local gunshow. It came with two barrels, a 10" .30 herrett and a 8" .44 mag i now know that the .30 herrett is a reloader only but the question comes about the .44 mag. It looks like it's ported and it has threads in the end of it. am i missing something important and if so does any one have one for sale or where can I get it? I havent shot it yet as I am not sure about it. thanks for any help.
