I like 9mm for a handgun intended for defense against 2-legged predators.
The added penetration that .40 brings to the table doesn't justify the longer splits, parts breakage, capacity reduction, increased risk of over-penetration and ammo cost/availability.
Having said that, if I was forced to carry a 40, I wouldn't lose any sleep over it.
