SORRY for not being clear.
I have a 12 gauge SA-08. I always thought that you needed to put a shell in the carrier for multi shots, (from the mag,to the carrier., to the chamber) but the other day a friend who has a Franchi said the I did not need a shell in the carrier for multi shots and he was right. So if I can bother you to explain what is the purpose of the shell carrier. Tks in advance and sorry again Gord
