I still have it. That said I would think in a situation like this, life and death, a gun fight, adrenaline pumping, the instinct for self preservation kicking in but having to stay focused and run to the sound of the gun fire any one of us would have emptied an entire magazine and then some to make sure your target doesn't get back up.
“...emptied the magazine...”

Pistol wounds do not normally cause instant incapacitation except on TV. (Rifle wounds are a different matter.) There is a phenomenon called “emotional fainting” whereby a person falls down when shot because his mind has been conditioned to do so. Many folks however do not even realize that they have been wounded and so keep fighting.
A “mag dump video” is a YouTube video showing someone, almost always cops, shooting a gun empty, usually because of stress response, and sometimes also because “it took that many shots to “stop” him. Cops continue shooting until the threat stops, which we all understand and justify, but the simple fact is that it takes time for a man to bleed enough that he forgets how to fight anymore.
Read about handgun wound effectiveness at this link to the FBI paper on the subject:
“...would have emptied an entire magazine.”
As long as you have more mags. One of the first things one of the cops did was look around for any more threats.
