When I was a young tadpole growing up on Hopalong Cassidy, Gene Autry and Roy Rogers westerns, when the guy in the white hat shot the guy in the black hat the bad guy would wince and fold slowly – that is unless the good guy decided to be magnanimous and just shoot the gun out of his hand. Later westerns and cop shows got a lot grittier and you saw a lot of blood and people being blown over backwards. Blown over backward has become the modern movie standard in most cases now, and third party tales on the internet about as to the impact power and “stopping power” of the various combat handguns with varying loads.
Well, it turned out that whatever those early movies lacked in good examples of gun handling they had the right when it came to the actual effect of a handgun bullet hitting a human subject. The truth of the matter, friends, is that bullets don’t blow up people nor do they physically knock them over backwards. Not to say that people cannot react violently at times to being shot, but this depends on exactly what is hit inside the body, and the mental and physical state of the subject being shot. Small animals may react dramatically to this impact but things that weigh 100 lbs or more often do not show any immediate reaction – other than to keep fighting or run faster.
Now this is not another article on 9mm vs .45. It is not about “stopping power” per se, but we all need to accept that the illusions we see on the silver screen are just that – illusions and for entertainment purposes. If you expect your .44 Magnum to bowl people over with a hit to the midsection you may be in for a rude and fatal shock!
So, would I say that caliber or “power” do not matter at all? I cannot bring myself to say that. I see a difference in cases that come across the desk and in the hunting fields, but that difference is subtle, not so drastic that you can say unequivocally that caliber A is so much better than caliber B that if you carry A you cannot go wrong or that B is a silly choice… within reasonable parameters.
