COLORADO SPRINGS, Colo. -

The Transportation Security Administration says a loaded gun was found at one of its checkpoints at the Colorado Springs Airport Thursday night (7/24/14).

The incident happened at around 7:15 p.m.

The TSA says its agents found a .22 caliber Derringer revolver, loaded with five rounds, during screening at the checkpoint.

TSA immediately alerted airport police, who took possession of the weapon and cited the passenger on a local charge.

"Firearms and ammunition, along with firearm parts and realistic replicas, are always prohibited in carry-on bags," said TSA spokesperson Carrie Harmon. "Passengers should check their bags before coming to the airport to ensure they are not bringing these or other prohibited items."

The TSA says these items can be transported in checked baggage, provided the traveler declares them to the airline during the ticket counter check-in process.  Firearms in checked baggage must be unloaded and stored in a locked, hard-sided container.   

This is the second firearm discovered by TSA officers at the Colorado Springs security checkpoint this year. Three firearms were found here in 2013.

Nationwide, TSA officers have found more than 1,020 firearms at airport security checkpoints so far this year.

TSA has the authority to levy a civil penalty against a passenger who brings a firearm to the checkpoint.
