My understanding is speed makes a big difference in armor penetration. So, if anything, wouldn’t 9mm stand MORE of a chance at penetration on those frying pans?
I don’t really see this as a reason to not use 9mm for concealed either way. With JHP, you can transfer most of that speed into stopping power anyway. So definitely not going to stop using it.
Lol using 9mm and stopping power in the same statement

I don't understand what is undesirable about having a reliable round, with easy followup shots, and reasonable penetration. It's a pretty standard round to carry.
You could try to make an argument otherwise, other than pointing and loling. That would actually be, well, informative.
You ever notice that since the inception of the hollow point, stopping power has been reduced? That goes for all calibers. 9mm and the .38 Special was never inadequate when carrying ball or flat pointed ammo.
@libertysnake , speed doesn't equate to stopping power. That's a myth. Check out the FBI Ballistics Manual linked below.

There is no force wasted or put into a body. Well there is but it's very minimal. It's about the same force the shooter gets with recoil without a recoil spring. Ammo companies have exploited these energy numbers to sell ammunition.Not saying it equates 1:1, but hollow point prevents the loss of some of that force that would otherwise be wasted from overpen in 9mm.

Read the FBI Ballistics Manual. Also look at shootings where the victim survived and vitals weren't struck. What did that energy or force do? Absolutely nothing. All that happened was that a hole was created that caused bleeding but didn't incapacitate the individual.
Speed doesn't = Stopping power? Hmmmmm, OK! Speed does = Energy, and the most energy wins! That said...
It all means nothing if you can't "place" your shot reliably! A .22 round in the "right" location will do as much as a .45 in the "right" place. Fact is too many people place importance on the intangibles rather than what is or isn't effective. If as much $ and time was spent on actual shooting and improving skills as buying gadgets or so called "better" ammo, then the ballistic discussions would disappear! There are no magic bullets, lol, pun intended.

Correct but energy doesn't kill. At least with handgun energy numbers it doesn't. If it did than a shot to the gut in an immediate non vital area will kill a man instantly where he stands.Speed doesn't = Stopping power? Hmmmmm, OK! Speed does = Energy, and the most energy wins! That said...

There is no such thing as stopping power with handguns. Handguns the only way to get a reliable stop is to be able to hit the CNS, or massive blood loss in a very short amount of time..
Oh as for your first statement, you can have a hyper fast round but you also NEED mass to go with it for that speed to add anything for increase in energy.
9mm going 2,000 fps but 50 grains is 444 ft/lbs
9mm going 1,150 fps at 124 grains is 364 ft/lbs
Only 80lbs difference.....
.22lr 40 gr 1070fps 100ft/lbs
@Cooolone , you aren't really being a "Cool One." More like a "Hot head" actually is what I'm seeing. If you reread my post, I did say that you were correct and then I made my statement regarding energy to "Pistol Rounds" rather than rifle rounds.
.22 vs .45 isn't a really valid comparison since the .22 may have penetration issues so in that case the .45 wins. But if shot in the stomach with either a 9, .38, or .357 Sig or Magnum of the same diameter, neither will do more damage than the other assuming they penetrate the same depth destroying the same amount of tissue. The higher energy of the higher velocity rounds is still too slow to make a difference in a body. That was my point.
With a high velocity rifle round, that is a different story all together. The greater the energy, the greater the temporary stretch cavity that stretches beyond elasticity creating bigger wounds.
I've seen gel tests that actually show the higher velocity .223 do more damage but fail to exit the block while the x39 always does exit but does less damage to the block.My understanding of common rifle rounds is, unlike a .223 / 5.56 / 5.45, which all shatter at some point as part of their wound profile, the 7.62x39 of my AKs creates a larger cavity while not shattering and creating a larger exit wound. So different wound profile as a defensive round.
I’ve heard benefits to both rounds at sub 100 yards though. Thoughts?
I've seen gel tests that actually show the higher velocity .223 do more damage but fail to exit the block while the x39 always does exit but does less damage to the block.
But then you have higher grain .223 that go much slower and do less damage in gel but exit. So I guess it all depends on the round. Some are designed to not fragment at all.
