That's my opinion also. I'm not a big fan of .40S&W because of the harsh recoil and although .45ACP seems more manageable to me I don't need another caliber to feed. I have a lot of confidence in 9mm for personal self-defense scenarios and I do believe statistics bear that out, just like they bear out the other two named calibers.
