Dan Wesson revolvers have to be the best deal in double action revolvers going. Most people know nothing about them so prices are still good however more people are learning of them and driving prices up. I'd rather have a Dan Wesson than any of the major name guns in double action revolvers. Not that the other brands are bad but I like the best accuracy possible.
These guns are also very strong and will handle heavy loads by the thousands and stay tight, they were designed for it. The action is very simple and if you're mechanically inclined at all you can work on it yourself. Slick up the action and put some Wolf springs in and you'll have a very nice trigger pull. Best knowledge base for these guns is:
