> An Ar-15/M16 can go off without pulling the trigger if the firing pin gets stuck in the channel. That won't happen with a glock because the safety physically blocks the primer from being struck. This is precisely one of the issues with Gen1 Glocks that was remediated. The firing pin safety prevents the firing pin from moving forward unless the gun is in battery and the trigger is partially depressed. It doesn't force the pin to move backwards if it is jammed forward (due to dirt). A pin that's jammed will slam fire the gun when racked. Always rack in a safe direction.
