No. When the flight officer is on the flight deck, he removes the padlock and wears the weapon. If the flight officer leaves the flight deck for any reason, he must remove the weapon from his belt and padlock it before unlocking the cockpit door. He must also have the weapon padlocked when walking through the airport.
Here is another youtube with the same expert explaining the procedures. I hesitated to use this clip the first time because it is from the Communist News Network.
Thanks for the info. Seems to me if the weapon can be discharged even with the padlock, the lock is nothing more than show. I carry the Glock 22 in .40 and the safety is built into the trigger. Assuming the 9mm is the same? If so, maybe they should switch models where the safety is somewhere on the frame. I’m sure the padlock is for PR because it serves no purpose other than to give the false appearance of a secure weapon.
I have dial-up internet and if I clicked on your links now I probably wouldn’t get to watch them until tomorrow this time.
