I have owned and shoot .45 ACP, 9MM Luger and .40 S&W and I have settled on the .40 S&W in a Glock 22 as my primary handgun. I like it over the 9MM because it gives me a little more pop and over the .45 ACP because it gives a higher capacity in a smaller frame.
In my own, very unscientific, tests, I found the .40 S&W HP to expand every time and the .45 ACP HP marginal and often failing to expand at all and the 9MM to lack the penetration of either. I realize my findings are mine and mine alone, but that is why I picked the 40 S&W. The platform being a Glock needs no explanation.
