I have a barely used Ruger ( RUGER GP100 357 Mag - Model # 01705 ) that I could probably sell on my own for about $550. I bought it about 5 years ago and took it to the range once. Works fine. How much would you expect a dealer to pay for it? I plan on going to the same dealer that I bought it from AND I want to buy a new gun from them as well. I sold a more expensive gun once before. It's too much of a hassle to sell this cheaper on my own. I just wanted to get some ideas as to how much to ask/take.
