No! More likely his shirt tail caught the trigger and it pulled on the trigger. Don't be quite so hard on the guy. #### happens and it could have been you. The trigger safety only works if the outside of the trigger is the only part of the trigger that gets pulled. I would not bet a plug nickle on that happening anymore than my life or my twig and berries as the Brits say.
I am having a brain cramp what is the third? Neither of the two I mentioned helps much if the shirt catches the trigger.

The trigger tab/bar safety prevents the trigger from moving unless pressed. This helps prevent the gun from firing when dropped, like a SIG320 does. The firing pin block prevents the firing pin from striking the primer unless the trigger is completed depressed to the rear. The third is what is called the drop safety. The striker mechanism known as the "crucible sear" has two wings that ride in tracks within the trigger mechanism housing. Those tracks are parallel until the striker spring is completely compressed(which means the trigger is pulled completely to the rear) at which point the tracks allow the crucible sear to drop down allowing the striker to travel forward and do it's job. The contact between the striker and the crucible sear is continuous until the trigger is pulled with no chance of separation. By the very nature of PASSIVE safeties like those in a Glock, there is no way for ignorant/negligent behaviour or practices to be mitigated. You press the trigger with anything and all three passive safeties disengage and the gun fires, as designed.. Much like a revolver.
