I’m looking to get my son his first shotgun sometime in the next few months. He has a .22 cricket right now and is doing very well with it. I was wonder what any of you guys started your kids out on that was not to much for them. I have been looking at the mossberg 500 youth 20ga. Should I go with a single, pump or semi auto? He is average height and weighs around 55 lbs if any of that helps.
