The Benefits of Requiring a Criminal Background Check for Every Gun Sale
[C]urrent federal law requires criminal background checks only for guns sold through licensed firearm dealers, which account for just 60 percent of gun sales.(2)
That means two out of every five guns acquired in the United States - including guns bought at gun shows, through classified ads, and between individuals - change hands without a background check. Statistical analysis indicates that extending criminal background checks to all gun transactions in the United States could prevent nearly 120,000 additional illegal gun sales every year.
