and this doesn't apply to 9/40/45 which have also suffered the same short comings when applied to BG's?
other than cost and training im not really seeing a damning reason not to.

These are great posts from 2012 that cover picking the right ammo, which is great and again emphasis on shot placement, but these are also centered around departments use/MIL from the poster's presentation.Some perform better than other...

What about 9x29mmR ?Carry one of 3 guns, a sig p229 dak in .40, a fnp45 (winter/ cold weather guns) or a model 49 s&w 38 special (summer gun). Don't even consider a 9mm feasible. Not looking to start an argument, it's just my preference.
I prefer the 9x33R... Just sayinWhat about 9x29mmR ?
I had all but forgotten about that round. Don't seem to hear anything about it any more. I suspected when it came out it may have a short life span.

"knock down" used to be a VERY common thing before the net came along. TV and movies used to show it and an alarming number of shooters believed it. I used to take anyone who would not believe me to a shooting spot and shoot a 50# bag of sand. It would of course not move off the table. I would then tell them if it will not "toss" that 50# bag how is it going to toss a 200# person? MANY would look on in shock as they had been told all their life a fiction and they could not believe what they were seeing. Now when the term is used I have to assume they mean they are hoping for one shot stops. That too is VERY subjective now days. So many video of people pumping multiple rounds into some drugged up zombie who just will not go down since they can't feel pain. Can be scary as all hell to watch.Physics don't lie. I have both calibers that are originally being compared, and have carried both. I now carry a PMR 30, my wife has a 651PD. I'll get one too as well just as soon as I can afford it. Ask a farm butcher what he shoots those big steers with...it will most likely be the lowly 22WMR. Then watch comparisons between that and the 5.7.
I used to hunt exclusively with a handgun, and having killed 17 deer, 2 elk, and some other critters, all with a 44 RM and some really, really hot loads; there is no such thing as "knock-down power" that I've seen in my 44's. Maybe the 9's, 40's, 10's, and 45's have it. I don't know as I've never shot any Sitka Blacktail, or a Roosevelt elk with any of them. I do know that my 44 wouldn't "knock" one down.
One tenth of an inch difference in diameter makes little difference in "shock effect" (0.452 minus 0.355 == 0.097"). Even expanded the difference is minor; fractions of an inch.Just one point: greater surface area gives greater shock effect.
All things being equal, same weight and velocity across .45, or .40, vs 9mm leads to greater shock effect.
BUT we keep talking about this because "all things are NOT equal."
Inertia being one not often discussed. Talking different calibers, "all things being equal' doesn't typically translate in real world application.In short, there are just too many variables to make wide sweeping generalizations about bullet caliber. Mass, velocity, bullet design, the target composition, are just a few of the variables.
