“Currently, gun stores are required by law to conduct a background check for every gun sale. But, for decades, many dealers who sell weapons someplace other than the traditional gun store — say, for example, a gun show or a flea market or even through social media — have gotten away without conducting background checks. This is the so-called ‘gun show loophole,’” she stated.
That is not entirely true. As I understand a law if an FFL is selling at a gun show out of his stores stock a background check has to be completed. If the FFL is selling a gun from his personal collection there rules on how long he has had to have owned before making a private sale where a background check is not required. Unless it is a state that requires background checks for personal sales.
