That incident makes me rethink my EDC weapon, to a firearm with a larger magazine. I understand the young man that ended the shooting spree was using a Glock, firing 10 rounds. None of the reports have indicated the caliber of the Glock, I'm guessing 9mm or .40. Reports indicate the mall is a "gun-free zone". I'm glad the good Samaritan used common sense and ignored the signs.
