About 30% more guns were found at airport security check-in in the first six months of this year compared to 2012, the vast majority of them loaded and about 1 in 4 with a bullet in the chamber ready to fire, analysis of the database we maintain by transcribing Transportation Security Administration data shows.

Atlanta, Dallas-Forth Worth and Phoenix airports topped the list, with a combined 15 percent of the 899 guns confiscated by the TSA at 168 domestic airports. Half of the top airports were in Texas and Florida.
