no it is not on safe if the threat was severe enough for him to draw the weapon it is ready to go ... by the way a Glock which most carry today have no external safety, the safety is the way the trigger is designed, it takes a deliberate pull to discharge but the gun has no external safety feature it is all built into the trigger. There is a small catch on the trigger that engages to discharge the weapon but it takes a deliberate finger pull not something just catching on it accidentally. Pretty neat design actually.
