Enforcement began June 1.
A record 155 guns had been detected at Hartsfield-Jackson through Oct. 17. The previous record for a calendar year was 144, which was set in 2015.
If a gun is detected at a checkpoint, a Transportation Security Administration agent will sound an alarm and the lane is closed, the AJC has reported.
The passenger is escorted by Atlanta police to the airport precinct.
The guns detected at security checkpoints are loaded about 83 percent of the time, the TSA has said.
