The TSA spokesperson said that officers detected a loaded 9 mm Ruger LC9 handgun on Monday morning.
It is the second loaded handgun detected at the SLC Airport in the past week during routine carry-on baggage screening.
TSA officials say the gun was loaded with seven rounds of ammunition and one round in the chamber, and was found in the carry-on bag of a male passenger headed to the Greenville-Spartanburg, S.C. TSA officers also found a separate 9 mm ammo magazine in the passenger's bag.
On Tuesday, Oct. 4, a .380 caliber Kel-Tec pistol loaded with five rounds of ammunition was discovered in the carry-on bag of a passenger headed to Atlanta. Both men were arrested by the Salt Lake City Airport Police on state charges.
Nationwide, TSA officials say officers have found more than 800 firearms in carry-on bags this year.
Depending on local laws, passengers are allowed to store weapons with their checked baggage.
