Certain 12ga guns sell very well. One is Remington 870 Wingmaster with Light Contour barrel. Remington sells every one they can make. That is not surprising as Wingmaster Super Magnum (most out there are standard receiver models that can take up to 3" shell) can handle 2.5, 2&3/4, 3 and 3.5 inch shells and comes in at about 6&3/4lb with surprisingly good balance.
