HI is dangerous. There’s too much going on at all times and there’s not enough RSO’s to keep everything under control. The unsafe gun handling is rampant and when it’s brought to the attention of the RSO’s they don’t do too much about it. The inspections at the sign in table are also dangerous.
Just think how dangerous it would be if they allowed drawing from a holster and FA on the rifle line?
If you go, bring a buddy who knows how to apply a tourniquet and basic first aid.
I'm curious what you find dangerous about the inspections at the check in station. All muzzles should be pointed in a safe direction.
As for carrying a 1911 with the safety off in a Fobus Holster, . . . , I wonder how you even made that observation, unless it was an ambi safety.
Even in that case, it is no more unsafe than carrying a Glock with the safety off and a round in the chamber.
The holster was covering the trigger. Perfectly safe.
