The problem is you're basing your argument on a photo of the round's performance in ballistics gel. Actual real-world shootings have shown that, when it comes to actually putting an attacker down, the advantage a .40 has is marginal at best.
Nobody is arguing that the .40 doesn't have better terminal ballistics than the 9mm, we're just saying that the real-world difference isn't anywhere near as big as some people think it is.
9mm, .40, .45; with good hollowpoints they're all pretty close as far as performance and none are that great when it comes to putting the target down as quickly as possible. That's why I use an AR-15 for home defense.
