The question of whether the case or bag is secure enough will vary by the TSA inspector. I flew from Austin to SC and had no problems with the case leaving Texas, however the TSA agent on my return flight wouldn't accept it. I ended up mailing my pistol back to myself [0] The criteria seemed to be that the case or bag can't be pried open enough to dump any of the contents out (gun, magazine, ammo, etc). Which makes sense until you realize that a thief is just going to take the entire thing and open it when they get home... Experiments showed that even a Pelican brand case isn't sturdy enough to prevent this. The only one I've found that works are the cheap stamped steel pistol cases (with the easily picked wafer locks). You can't pry open a corner on them with just hand strength.
