Since 1994, the federal law requiring background checks on licensed gun sales have blocked over 3.5 million sales to felons, domestic abusers, and other people who aren’t allowed to have guns under existing law: https://everytownresearch.org/background-checks-save-lives-protect-communities/ …
When Connecticut passed a law requiring all handgun buyers to pass a background check both at the point of sale and as part of a permit process, it was associated with a 40 percent reduction in the gun homicide rate and a 15 percent reduction in the gun suicide rate.
By contrast, when Missouri decided to repeal its purchase permit law requiring background checks, the state experienced an up to 27 percent increase in its firearm homicide rate and a 16 percent increase in its firearm suicide rate.
Requiring background checks for gun buyers is the most comprehensive intervention to keep guns out of the wrong hands. Loopholes enable criminals to get guns with no questions asked, and make it difficult to enforce the law and protect communities from gun violence.
