O/U are just badass and have a 2 different choke benefit. BUT if you can afford it I would recommend a reliable semiautomatic. I have single action, o/u’s and pump shotguns but I don’t have a semiautomatic. It’s where I wish I had went first. This is just some advice on the internet but if I had the funds I would be looking hard at a Benelli. I can tell you that I am.
