I don't get it..........
Obviously the holster design is flawed if you can create the discharge situation. If the requirement is to have the weapon secured when the pilot leaves the cockpit then why would a lock box be undesirable? Is the guy carrying with the pad lock installed?
There's no place in the cockpit to install a lockbox, and doing so would require major FAA approval. So now the pilot has to lug around a heavy lock box everywhere he goes.
