you'll find that most dealers, since they are so busy and all, will quickly run out of patience if you start asking more than a handful of questions.
I would gladly walk away from anyone who is not willing to take my questions seriously and answer them honestly. Business is more than an exchange of money and products. If they do not have the patience and time to answer my questions, then they have nothing I want.
I've had excellent experiences buying several second hand guns from Steve Barnett, Cabela's, British Sporting Arms, and Westely Richards Agency. In two situations things were not exactly right, and the dealers gave me all the possible options to correct the situation.
Sorry about the situation Hjoe...
