I have to agree with JRH. I have always gotten fair value plus for my guns before I even walked in the door, usually. If course that was the reason for me buying them and I was fortunate enough to foresee which guns were going to be valuable. Model 21s, Colt Pythons, Diamondbacks, S&W and Superposed. Even a blond could have figured that one out. But one has to realize that the SXS is not exactly the more preferred gun in the firearms industry. Even though some of us admire them and appreciate them, most would turn up their noses at them. So putting all one's eggs in the doublegun basket, so to speak, is not a good choice. Diversify. That way, when you decide it is time to sell something, you will always be in the market for someone. You will find that times are good and bad for each type of gun. And you will find that there are good and bad times to buy and sell any type of gun.
