What is "Knockdown"?
Posted: Tue Jul 22, 2008 11:28 am
I've seen this discussed here and on other forums, and there seems to be a continuing myth, fed no doubt by Hollywood, that a pistol bullet will knock a man down, or worse yet, blow him backwards as if he had been attached to one end of a rope being yanked on by a truck. Of course, saner heads dispute this. Unfortunately, saner heads are not found in great abundance in Hollywood.
In any case, I found the following two quotes recently which I thought I would share here:

I've told this story elsewhere on this board, but my dad shot a Japanese soldier at very close range (within 10'-15') in the stomach on Iwo Jima. When I asked him what happened to the enemy soldier, my dad said that he "sat down abruptly." He wasn't knocked down, or blown backwards. What happened is that either from traumatic shock or surprise, the guy's legs collapsed underneath him, and he went down in a heap. He did not move after that, so my dad presumed that he had killed him; but circumstances being desperately grim at the time, he did not make it his business to confirm it.You can't shoot down zeroes, blow up Tiger tanks, or sink the Bismark with a 1911 .45 ACP. Handgun bullets do not generate enough force to knock down an adult human being--if they did, they would knock us down when we fired them. [emphasis mine] This is simple physics. People do fall down most often when shot with a .45 because they are dead, seriously injured, or responding to the shock, but not because the force of the projectile is pushing their body down. The image of someone flying backwards after being hit by a pistol round is pure Hollywood, but not of the real world.

Given the amount of damage suffered by the individual above, and give that it dropped him "like a rock", the best you can hope for with a pistol caliber is instant incapacitation, but not a knockdown. If death follows, so be it, but it is not guaranteed.Well in my personal experiance with being hit by a .357 180 grain sjhp from five feet away I would say it stops a person most of the time because it dropped me like a rock with a shot to the gut one inch above my bellybutton. OUCH! Damage was as follows. Took half my stomach,half of my small and large intestines from fragments,20% of my liver and my right kidney. It stopped millimeters from coming out my back and was about 2 inches from my spine!
