If they weren’t more effective, battleships would have never carried 16 inch guns.
Having said that, I carry a 9mm when I need to conceal. I carry a SCAR 17 when I don’t need to conceal.

People try to complicate things too much. It comes down to whether you want a bigger hole or a smaller hole.
I want the bigger hole myself because in case I only wing them a bigger hole will be more discouraging then a smaller hole in the same location.

The one problem I saw with the article was then they were talking the size of the entry wound, not terminal bullet diameter or exit.

One need not make too much of a puzzle out of it. I’m guessing that the un-scientific factor of resolve makes more difference than caliber among the calibers mentioned.
Mike V makes a decent point also, though of course an expanded 9 mm will still be much smaller than a 45 that expands by the same percentage.
A high-powered rifle is a completely different animal, as the hyper velocity will result in an exit wound many times the bullet diameter.
Much under 2,000 fps target velocity, I believe it’s been determined that velocity makes little difference so long as it’s enough for good penetration. The exception would be that enough velocity (impact pressure, really) is required for an HP to expand properly.
Without expansion, my many hunting shots using lead, .495″ round ball have shown me that none of them have expanded significantly, and also that a very close hit (well above speed of sound, but under the 2,000 fps threshhold) does about the same things as a longer shot (hitting sub sonic).
Point here is that *without expansion*, velocity from around 950 to 1600 fps at the target seems to have made little or no significant difference, even though the energies are VERY different. It seems mainly to determine the amount of energy left over after a complete pass-through.
There are super-duper FBI science labs costing the taxpayer who knows how much, and then there are those of us who have killed many a man-sized, or similar-to-man-sized, quadruped in varying conditions over many years. One thing that has often stuck out to me in examining the effects is that a real live creature contains very different sorts of tissues, and bones of widely varying densities, hardnesses, and bulk, and that they all behave very differently when struck, whereas few if any such variables exist in test media.

When LE went from wheel guns to autos, they thought 9mm didn’t have ‘stopping power’. They were using FMJ’s that would just go thru attackers, pushing arteries/veins/nerves out of the way, and not causing any real damage. Gotta use the right type of ammo …
You could use Desert Eagle .50. But even .22 or .25 is better than nothing.
Remember: The bad guys don’t want to get shot with anything.

“There are super-duper FBI science labs costing the taxpayer who knows how much, and then there are those of us who have killed many a man-sized”
You oughta pass that info on to the FBI; they’ve probably never shot anything man-size before.

Doesn’t really matter what you shoot bad guys with if you shoot tfhem in the junk. .22, 50bmg. Meh. Shot placement is what counts. Like a previous commenter said ” no one wants to get shot”. I would add ” in the junk.” Heh. For reals.
