I have the same gun (except mine is in blue) that I bought brand new in '93. Back then I paid like $300 for it. I don't know how much you paid for it and don't know how well they hold their value, but I would think 3-350 would be a fair deal if it only has like 20 rounds through it. Take what you feel is fair. By the way, they are good guns, I have loved mine.
