The issue of “knock-down” power is simply the preparation of mathmatical possibilities. People picture the pain of any bullet being enough to stop an assailant and if this were true, we’d never carry anything beyond a .22LR. It’s easy to imagine this when it is us, the sane ones, trying to imagine being hit by a bullet. We cringe at the thought and for all of us in our right minds, any bullet WOULD be enough to sway our decision process.
However, how many attackers, or assailants, are in their right minds when committing a violent crime? A drug addict is your most likely criminal these days and because of the chemicals they have floating around inside of them, they might not even feel your shot let alone have it influence a change of direction or motivation.
Knock-down power is all about shutting down the physical capabilities of a body, hopped up on drugs or not. A person CAN continue to pursue you and fight you for quite a while if the bullet does not end the situation immediately for you. The average man can cover….. I think it’s 20’/second…. so how much time given someone’s starting distance do you have to really put an end to their intentions? Very little. And unless that bullet, or bullets, shut the body down, who knows what they’ll accomplish on you before their body expires from a fatal, but not paralyzing wound?
THIS….. is the core concern behind knock-down power. Ending things immediately, beyond the voluntary, conscious decision of the attacker.
