Most of the newbies to the shooting sport, or CCW arena, are polluted by "must see TV's" use of firarms. Shoot a BG - he flies across the room and actually breaks the sheetrock (sometimes even the brick...).
It is amazing how the body can still continue to function, although for a short period of time, after being shot in a non-critical (vascular, not N.S.) location. A BG could waltz around for minutes after being shot, pumped on adrenalin and shock.
About 3 months ago, here just north of Houston in Conroe, TX, a perfect and tragic example of this issue occurred.
A woman who owned a "mom and pop" small grocery store was working at night. A perp walked in with hood over his head and promptly displayed a 12ga shotgun. The woman sensed a bad situation and actually had her handgun out when the BG drew on her with the 12ga.
She fired only ONE round from a distance of about 1.5 FEET and hit the perp CM.
The BG dropped the shotgun, walked around the counter (woman STILL not shooting again!), wrestled the handgun from her and shot her 3 times.
The BG then, still with a chest wound mind you, tries unsuccessfully to open the cash register. He decides to leave and was found collapsed right at the front doors, dead.
She did well to recognize a bad situation and draw quickly but she was obviously not trained to expect the perp to be able to function after a single shot.
My wife and I always train with multiple double taps.
Be safe.
