I agree with these guys. I, for one, love prowling used gun shops looking for hidden treasures. If you know what to look for, you can get great deals as compared to new guns. Let someone else pay the depreciation. Many times, people will buy guns and not shoot them much or at all before they trade in. If there ever was a problem, Ruger service is excellent. (by the way, last month I found an "Old Model" Vaquero for 150 bucks, and in 95 percent condition).
Used guns don't necessarily mean that there are problems. There are guns nuts everywhere that have to trade for the latest and greatest, and we all can benefit from them! Good luck
