Transportation Security Administration agents found a loaded .380 cal. Kel-Tech pistol in a passenger's carry-on bag at 6 a.m. on July 11.
The discovery of the firearm, the tenth so far this year, matches the total number of firearms found in 2015.
After detecting the weapon, the TSA alerted airport police officers, who then took possession of the bag and escorted the passenger out of the checkpoint area.
"Passengers are responsible for the contents of bags they bring to the checkpoint," said Mark Howell, TSA regional spokesperson. "Our advice is to look through bags thoroughly before coming to the airport to make sure there are no illegal or prohibited items."
Firearms may be transported in checked baggage, if the weapons are declared to the airline in a proper carrying case and unloaded. However, they are prohibited in carry-on bags.
