Yep I was taught( and train) that if something needs shot once, they need shot twice. If someone can't control a double tap, then maybe they shouldn't be using a pistol in the 1st place( a SG?). IN fact, imo, if you haven't shot your pistol in the last week or so, I'd suggest not using it in an emergency. Alot of defensive shooters agree to "shoot them to the ground until they stop moving". I know that won't work in some situations, but definitely a double tap. I like, double tap, assess, double tap, assess, repeat as necessary. YMMV
