Hammertime
Marksman
I've flown with my sidearm several times. Mainly during the holidays. I have a small pelican case that perfectly fits my handgun, and several mags along with a box of ammo. You'll want to make sure you have NON-TSA approved locks. You can put the locked hardcase into your normal checked lugged, but you'll need to get a tag from the airline agent designating that its unloaded.
