In my previous post I was looking for a good shotgun to shoot the 3 gun matches. After doing a lot of research and getting input from many knowlegeable people, I have decided on getting the benelli m2. During my searching on this site I found several postings that said putting a mag extension on a benelli is illegal because of the import ban. Is this true. I am wondering then how people are using them in matches at the state and national level. I would find it hard to beleive that any sactioning body would allow illegal firearms to be used in competition. I am just trying to get this clarified before I spend my money and get in trouble.
