Can u convert a remington 870 express to a supermag. I have an express I'm wantin to build a turkey gun with. I would really like to be able shoot 3 1/2 shells. I was thinkin about it and all I would think u need to do is change the barrel. Am I right? Can I just slap a 21" supermag barrel on there an be good to go?
