According to Internet Gun Lore and “Experts” the only other gun that its lethality is somewhat close to the .45 ACP is the venerable 12 gauge shotgun. Both are known not only to freeze all movement at a molecular level on impact but turn time back at least 3 seconds.
Unfortunately life keeps proving otherwise and with the exception of placing lead in a very specific region of the human anatomy, most humans will not dies instantly when shot.
The event above happened in the Dominican Republican. The shotgun wielder one Victor Hernandez, was drunk and had been sent home for being drunk on the job. Apparently he returned to the business, shot his boss/supervisor and then himself.
Notice that even shooting himself in the chest point-blank range, did not stop Hernandez from staying upright and walking away. I am sure he collapsed soon after, but that was several seconds after Gun Lore has taught us that he should not only was supposed to die on the spot, but be sent at least two houses down by the power of the pellets.
That was the time between shooting himself and stepping out of camera. Now imagine you are facing an armed & dedicated killer armed with a side arm; you manage to unload the prefect shot of buck from your UFO Killin’ shotgun in his chest and lower your weapon because nobody can survive that and he has to go down right then and there, right? The question is, how many shots do you think he can unload on you in five seconds?
Oh yes, he will be dead, but so are you. Five seconds are forever when you are shooting, ask any IDPA, USPSA, SASS or any shooting discipline where the shoot with a timer. If you are even half way serious about shooting, you must have heard of El Presidente drill and that is done in 10 to 12 seconds time (or supposed to.) That is 12 accurate shots on three targets with a reload in there so even if you are drunk and shot in the chest by a shotgun at point-blank range, five seconds provides the shooter with plenty time to dump rounds your way.
Lesson to be learned: don’t break cover, don’t stop fighting and don’t do stupid stuff just because you shot your opponent with something people say kills instantly. Make sure he is down, you have time on your side, he does not.
