A major change which aims to keep more weapons out of the wrong hands is in the works for the Federal Bureau of Investigation’s gun background check process.

Examiners will be given access to a large, previously untapped database of more than 400 million records as they determine when gun purchases can go through nationwide. But for the survivors and victims’ families of the 2015 church massacre in Charleston, S.C., the change did not come soon enough…

The FBI’s plans for change are spelled out in reports and meeting minutes from its Criminal Justice Information Services Advisory Policy Board from December 2016 to June 2018. The board has been conducting a pilot program using the N-DEx database and called it “valuable in providing information” before the waiting period ran out. It’s not clear when the FBI will begin implementing the new plan, but the process is expected to take anywhere from nine months to two years. The N-DEx database will serve as a secondary search once a red flag is found in the NICS system, as was the case with Roof.
