- First of all, I'd like to thank everyone who replied to my posts of a few
- weeks ago on recommendations for a defense handun. I ended up buying a
- Glock 21, the .45 caliber model. I've gone to the range a couple of times
- and been very pleased with the way the gun performs.
-
- I recently picked up the Guns & Ammo annual and found something in the
- back that I hadn't seen before - ballistics tables! Thinking that this
- would truly demonstrate to me the wisdom in choosing a .45 over a 9mm
- (which was considerably cheaper from Glock, anyway) I looked over the
- energy of various .45 and 9mm loads. I was amazingly surprised to see
- that there are a number of 9mm loads that have greater muzzle and 50 yard
- energy than quite a few .45 loads. This was very strange to me, since the
- .45 had, by all testimonials, way more stopping power than a 9mm.
-
- On further examination, I found that nearly all .40 cals and 10mm had
- quite a bit more energy than even the strongest .45 that was tested (peak
- 10mm listed energy at muzzle was 684 ft-lbs vs. peak .45 energy of 534
- ft-lbs, for instance). When I looked in my Glock manual, I found that the
- manufacturer listed the .45 at 460 J of muzzle energy vs. 500 J for all
- other guns, except the 10mm, which was listed at 750 J, making the .45 the
- least energetic of any Glock pistol.
-
- My question is: what is the relationship between energy and stopping
- power? Due to its larger size, does the .45 gain over these higher energy
- rounds in stopping power, or are the smaller rounds actually better? I
- expect there to be additional factors to consider besides sheer energy in
- figuring out how good a slug is at taking down an attacker, but at what
- point can you say, "Well, that's pretty big, but this one's just so much
- (faster/more energetic) that this one is superior?"
-
- Or have I asked some sort of age-old debate question that has no clear
- answer? Any replies are welcome.
