Forgot I Had a full backup magazine in my jacket and proceeded to go through security at Austin's airport. TSA saw it when it went through the X-ray machine. Good they caught it I guess... Anyway, they pulled me aside and got an Austin cop to watch me. He asked me for my license and gave it to the TSA. he told me that the mag and ammo wasn't illegal, but it is against TSA rules for carry on. TSA fiilled out thier form and took pictures of the mag and ammo. The cop was actually pretty cool about the whole thing and didn't treat me bad. He asked if I had a CHL and I told him I did. I know I didn't have to tell him, but I chose to. He gave me two choices: 1 - he escort me out of the security area and he discreetly hands me the ammo and mag and I go put it in my car or B - he keeps the stuff and fills out a form and I could get fined upto $11,000. I chose option 1. While we were waiting on the TSA, he was encouraging me by telling me that I wasn't in trouble and that this happens a lot, especially in Texas. Had to go back through security after putting anything back in my car and still caught my flight.
