OP. Get the Maverick, you will not regret it. I had mine for 17 years before giving it to a friend so his son could hunt with him. I'm sure that someday the son will hand it down to his son or daughter, I am pretty sure it will still be getting used long after I am gone. A 20 gauge is an excellent do anything shotgun.
