Six guns have been confiscated from passengers at Denver International Airport in the past two months, four in the past two weeks.
The Transportation Security Administration is calling that high.
"It's very high and we are concerned 10 years after 9/11 we are seeing that many firearms," said Carrie Harmon, spokeswoman for TSA.
The large number of firearms is not overly surprising after the TSA released its numbers from 2011.
Across the country, TSA agents confiscated 1,306 firearms.
"The vast majority of people tell (agents) they forgot or they didn't know the firearm was in the bag," said Harmon.
"That's ridiculous," said Kathlene Dellarosa, of Parker. "You know when there is a gun in your bag."
TSA said nationwide, it catches about four guns a day at checkpoints across the country. During the last week of February, 25 guns were found, 21 of them loaded, four with rounds in the chamber.
In Colorado, Denver police said it's not against state law to have a gun at the airport if it's unloaded. If a person gets caught however, the Federal Bureau of Investigation will launch its own investigation to determine if the person intentionally tried to get the gun on a plane, is a felon or has any ties to a terrorist organization.
It's not just guns. TSA has found bombs, spear guns, knives and even grenades.
If a person is caught with a firearm at the airport and it's loaded, TSA can fine him or her up to 7,500.
