RWK, This topic has caused me to do some thinking. You see, I don't remember the last time I armed myself with a .380ACP. Usually it's a .40S&W or a .45ACP for home defense and a .38 special or 9mm for concealed carry. However, I seriously had to ask myself what I would be better armed with: my 14-round Browning BDA380 (it actually belongs to my wife now) or my 5-round Taurus model 85 and in all honesty, I have to save that 14 rounds of .380ACP beats five rounds of .38 special.
I consider myself to be a fairly good shot. Not great and maybe not even good by TFL standards but better than average. However, realistically, I have to recoginize that shooting at stationary targets under calm & control conditions and that is different from shooting at a moving target (who will be using cover for protection and might even be shooting back) under stressful conditions. I completely agree that the .38 is a more powerful round than a .380ACP and five well-placed .38 rounds is more than enough to end a hostile threat. I would say that even two or three center of mass hits with a .38 special would be enough to end the encounter (although I wouldn't want to bet my life on that statement). However, if you only wing a person once or twice and miss with the rest (which is very likely to happen against a moving target -- 1997 DOJ data shows that trained LEOs hit their intended target 10-20% of the time in real encounters), chances are that that will not be enough to stop him.
Under these conditions, a hi-cap .380 seems to be a better choice. Some will say that this is the old "spray & pray" concept but I have to disagree. In the 1950's & 60's, most LEO shootings had only two or three shots having to be fired. This would imply that LEO were well armed with a five shot revolver but no one accused them of "spraying & praying" because they carried a six round revolver.
The same thinking applies here. I am assuming that most LEOs are better shots than I am and if they average only a 10-20% hit ratio, it is very unlikely that I will do better. Using these odds, all five of my .38 special could completely miss their mark. Where as one or two rounds of .380ACP could hit their intended target.
Additionally, people who are recoil sensative (like my wife, Stephen's wife, etc.) will be more accurate with a .380 than a .38 or a 9mm due to it milder kick. In all seriousness, my wife can put the bullets in the X-ring at 75 feet with a .380 but she barely hits the target at 25 feet with a .38 snubbie. Under these circumstances, she would be better armed with the .380 because she is more accurate with it and chances are that she'll be able to land more center of mass hits with it than a .38 special.
The bottom line is: where those bullets that you fired end up? In the center of mass or some wall? Like I said, this topic has caused me to do a lot of thinking and I'm still not finished with my final conclusion -- the wheels are still turning up there and I'll chime in with more comments as they come to me. Regards, FUD.
