I bought a used stoeger semi auto shotgun for my son as a Christmas gift, the only model i can find on it says Luger on the left side of the receiver, the stock looks like wood but sounds like plastic, I saw a similar shoutgun on GB that was listed with a starting price a lot higher than what i paid for this one but looks exactly like mine and says the stock is "cellulite ? " and that it is a model 3000, but it doesn't say 3000 anywhere on my gun. is there a sight or page where i can enter the serial number to find out the exact model and date it was manufactured,, mostly wanting to find out so i can get him a couple of different choke tubes. thanks for any help
