I have over 50 purchase transactions on GB, most of them handguns. I have had exactly two issues. In one case the pictures were of the incorrect gun. In that case the seller gave a full refund including shipping. The second one was a private seller who was hesitant to provide a legible driver's license....Other that that, I have done pretty well on GB. I check feedback and don't buy from sellers with little, feedback or who have many negatives.
