You did great. I have two. One pistol grip and one for duck hunting.
They are great guns, built around the benelli action. They do have some quirks at some times. Best piece of advise i can give you if you have trouble is to go on Shotgun world forum. They have a stoeger section. There is a guy on there name Dave Clarke that is a retired gun smith. He can help you solve ANYTHING that comes up with your m2000. My run like tops.
