From The Truth About Guns:

NSSF released the adjusted National Instant Criminal Background Check System (NICS) figures for October. They aren’t record-breaking. They’re a record-shattering 1.76 million background checks completed for the sale of a firearm across the nation. That brings the annual total to 17.2 million, leaving the previous record in the rear-view mirror. That was 15.7 million background checks in 2016, also an election year, when Hillary Clinton promised to re-enact the failed 1994 Assault Weapons Ban.
