there is also no question that the 40sw has a significant boost in power
Here's my question: How is it that people still believe this stuff? Look, when using modern hollow points, 9mm, .40, and .45 are all basically the same in terms of terminal effectiveness on the human body. Each caliber has its stengths and weaknesses, but when it comes to "stopping power", the three calibers are virtually indistinguishable.
This thread is sure to turn into yet another caliber war. And that's too bad, because the truth is caliber matters a whole lot less than most people think it does.
