I got an 870! FOR $250! There's a firm here that manufactures them. I can not believe what a good design this is, with the interchangeable barrels and all that. marvelous, good feeding and a good recoil pad. What's a good pistol grip stock for it? I mean pistol grip as in AR15 or AK style stock/grip configuration, not shotgun no stock pistol grip. I have heard that some on the market are just horrible. Thoughts?
