9mm +P+ vs .357 Magnum
This Buffalo Bore 9mm +p+ is 115 grains and goes 1426fps out of a BHP with about 500 ft lbs of muzzle energy:
This Federal .357 Magnum JHP 125 grain goes 1,450 fps with 584 ft lbs of muzzle energy:
The .357 goes 30-50 fps faster with 10 more grains, but is that really enough to make a difference? These two loads seem to perform about the same. That .357 load is one of the most respected for stopping power, so does that mean that that 9mm +p+ has about equal power? It would seem so.
Granted, the .357 Mag can be loaded much heavier and hotter than the 125gr going 1450 fps, but that's about the standard for SD ammo.
So are these loads about equal? Not only that, but you get about 15 rds vs 6.

Given adequate penetration--penetration that will put the bullet into something vital--and the same permanent wound channel, one .356 or .357 dia. bullet, expanded, is as effective as another.
What the bullet hits is a function of skill and with a moving target, luck. One shot may well fail to stop quickly. Or the first shot may not do the job, and the second or third may do so.
But speed may be of the essence, if an attacker is bent on mayhem. Getting four shots into the target in less than a second will likely be a lot more difficult with a firearm that recoils violently.
For that reason, a +P+ load, or a .357 Magnum, may not be the most effective choice for defense. Another reason, if home defense is the objective, is the excessive muzzle blast and noise.
Contrary to myth and folklore, the .357 Magnum was not adopted to replace the .38-44 heavy duty, and the latter was not selected to replace the .38 Special high velocity, because of "stopping power." The reason had to do with penetrating car bodies.
That's something that most civilians will have difficulty justifying.

You've got a point, but it is apples an oranges to a certain degree. You're comparing 9mm at its near hottest load to a middle of the road 357 mag load. Not quite a fair comparison.
The point is taken though, +P+ 9mm loads perform fantastically, even approaching .357 power.
At some point will inevitably come the argument: "But why have 15 maybe when you can have 6 for sure...?"
I'll probably catch flak from the revolver guys for making light of that argument, as I frequently do.

Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
