The bad thing about The Blue Book, those values are outdated by at least a year when the book is published. I use it as a guideline. From what I have been seeing, and spending, S&W guns are worth more than that book is valuing them at. Some S&W models (I'm not sure about other brands because I haven't checked but I would bet the same) listed are actually sold from wholesale distributors for more than the 100% listed value being shown in the Blue Book. The Blue Book is out of date with current demand and market price of fuel, manufacturing, and material costs.
