Go to one of the big stores, Dicks, Bass Pro Shop, Gander Mountain, etc., and hold and feel as many different kinds as you can. Close your eyes, shoulder the gun comfortably, hold your head in a comfortable position, then open your eyes. You should be looking directly down the rib and see nothing but bead. If you're looking at the top of the rib, the gun doesn't fit. You should have an unobstructed view of the front bead, or if it has a center rib bead, they should be lined up and look like one. Price isn't everything. A shotgun must fit in order for you to shoot it well. Even shotguns of the same model that are stocked in synthetic and wood can "fit" differently. Try as many as you can, and don't buy something you won't be happy with later just to save a few bucks. If the one that "fits" costs a bit more, then save for it. You'll be glad you did.
