Hello everyone. I was hoping to get some from the shotgun pros here on the forum. First of all I am a total shotgun newbie. Just ended up with a benelli m1 in a trade. The shotgun however is missing the follower. my question is where and which follower do I need to get? The shotgun does have a aftermarket mag extension on it (not sure of the capacity r the manufacturer and I cant get ahold of the original owner atm and I do not have the shotgun yet, arrives next week). Any help would be appreciated. Here is a couple of pics of the shotgun. Thanks guys!
