Does anyone have any knowledge of or experience with a CD Diana semi-auto shotgun? Specifically I'd like to know what they are worth and if they are reliable. I won one at a local ducks unlimited dinner and I've never heard of them before. I tried a google search and came up with nothing. It is a basic gas operated semi-auto with black synthetic stocks and a matte black finished barrel and alloy reciever. It says imported by Tristar Sporting Arms Kansas City, MO on the barrel. Any info good or bad would be greatly appreciated.
