GR, it is clear that you enjoy shooting and gun lore. We applaud that.
I'm not at all sure about your appreciation of defensive shooting, however.
Do not take that personally. We all start out there.
When I started carrying a dozen years ago after decades of handgun shooting, my thoughts on defensive shooting were based on the following:
- Slow fire, such as I practiced at the range, would suffice.
- The bullet(s) had "knock down power", based in KE or momentum.
- Not too many shots would likely be required--I had never studied human anatomy enough to rid myself of the habit of thinking of defensive shooting in terms of the impact of bullets on water jugs.
- My .45 ACP would certainly be more effective than my 9MM--it kicked harder, it struck jugs more impressively, and here were the stories of the advantages of the .45 Colt over the .38 Long Colt in fighting the Moro fanatics on Mindanao.
So--I carried the .45.
Then one of the staff here posted some data on the .45 vs the 9MM that caused me to reconsider.
Then, I read, and reread, the study
Handgun Wounding Factors and Effectiveness, from the FBI training Academy at Quantico. From that I learned quite a bit, most importantly that it is
what is hit inside the body that counts. Since one cannot see those things to try to aim at them, one must rely on shooting more shots, quickly.
I availed myself of some defensive shooting training.
My first class involved nothing but Bill Drills. We started out learning to shoot
very rapidly--more rapidly than I had ever shot before. Up there with what one sees on LEO bodycam videos.
I found myself at a significant disadvantage compared with those shooting the .40, and more so compared with those with 9MM pistols.
I put the .45 away and started carrying a 9MM.
It is natural to believe that the gun with the harder kick, bigger blast , and louder boom will "hit harder"--until one learns that when the target is a human, it does not.
More from Quantico:
- 9mm Luger now offers select projectiles which are, under identical testing conditions, outperforming most of the premium line .40 S&W and .45 Auto projectiles tested by the FBI
- There is little to no noticeable difference in the wound tracks between premium line law Auto enforcement projectiles from 9mm Luger through the .45 Auto
- The majority of FBI shooters are both FASTER in shot strings fired and more ACCURATE with shooting a 9mm Luger vs shooting a .40 S&W (similar sized weapons)s select projectiles which are, under identical testing conditions, outperforming most of the premium line .40 S&W and .45 Auto projectiles tested by the FBI
- Given contemporary bullet construction, LEO’s can field (with proper bullet selection) 9mm Lugers with all of the terminal performance potential of any other law enforcement pistol caliber with none of the disadvantages present with the “larger” calibers
Those findings have been accepted by all Federal agencies and by the majority of police departments.
One can read about these things, but the best way to gain a real appreciation of them is to attend a really good defensive shooting training session.
I was fortunate to take the I.C.E. PDN Combat Shooting course under Rob Pincus himself,
I recommend looking into it.
