Someone please correct me if I'm missing something.

Your numbers agree with mine. Maybe not exactly but pretty close. 2.39/1.44 = 1.66 or 66% more volume. A couple of posts up I calculated 63% more. The difference is just rounding errors because I used .452 and .354 for the diameters.
More, but not nearly 3 times the wound volume as the post I was responding to claimed.

The basics, as I understand it, are fast rifle rounds ARE moving fast enough for velocity to matter, but even the fastest handgun rounds are not.

Personally I don't put a lot of faith in Ballistic Gel.
I also don't put a lot of faith in the FBI Ballistic Tests. There seems to be no consistency. Trying to make one size fit all in weapon and ammo selection.
I just not a fan of JHP's.
I like hardball in my 45's and full hard cast wadcutters in 44 special and 38 special.

I too, like wadcutters and hardball in .45ACP. It starts out as a.45 inch whole and will only get bigger...........

There is a good bit of truth there. The 9mm may expand to .45, but the 45 ACP will not shrink to 9mm.
I am a fan of expanding bullets, expansion with proper penetration makes them more effective. Even more important, though, is reliability and shot placement. A 9mm that always expands to 3/4 of an inch, but does not function reliably in your pistol is useless. Same goes for a wonder bullet that misses the intended target.

Close, but not quite accurate. The argument for those units with a counter terror role is/was that terrorists are criminals, not lawful combatants, so not eligible for consideration under the Hague Convention. This information was provided to me by the lawyer assigned to "one of those units that do not exist" mentioned so romantically above.
I'm way out of date with this stuff, so if a decision has been made to general issue HP ammunition along with the new SIG that's news to me, and must be based upon some other, new consideration.

Holes bleed. bigger holes bleed more. Lots of bigger holes bleed even more.
The only time that I use FMJ is when I am required by circumstances to carry something smaller than usual. For example, .32 ACP out of a KT P32. Those HPs won't expand, and possibly won't penetrate enough. So, while the FMJ won't expand in that caliber, it will penetrate better.

Groo here
The Fmj was NOT designed to wound!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
It was designed to FEED and FUNCTION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Many forget this in their search for the "perfect " carry load...
First the round MUST feed and fire....
Then it MUST go where you send it......
Then it Must drive deeply enough to get to the good stuff!![ different summer and winter due to clothing]
After that ,, if it deform , does or does not go through is secondary.
It MUST do the first three or it does nothing.....

i'm pretty sure the correct answer to this question of FMJ vs JHP is buckshot

Wow there some good interesting points in this thread. FMJ ammo is used on paper targets and other targets. HP are used for SD. First use some of your SD ammo on your carry weapon, about 200 rds. If you have not hang up you are good to go.
Simple

Not two FBI agents and two bad guys dead. This is why the FBI tried to go to 10MM.

Platt and Mattox were both shot to hell and back and still managed to carry on until Ed Mireles took them both out at nearly contact range with his .357. That he was able to end the fight with his left arm blown nearly off was a testimony to true grit.

A long time ago I was a USMC Combat Pistol Instructor, I also went to the FBI Firearms Instructor's Course. I had two films about this shootout that I used. One was the FBI's film on what happened, with the Agents that were involved discussing it. The shootout sequence was very dry to watch. The second movie was "In The Line
of Duty:The FBI Murders" In the Line of Duty: The F.B.I. Murders (TV Movie 1988) - IMDb . Yes, it is a movie, but the shootout is almost spot on in accuracy. I urge all to watch it.

I'm the OP for this thread and I stepped away for a little while and haven't checked it, but I came back today and thought without a doubt you had the very best answer of everything I've read here!
Back in the day when I was teaching EMTs and Paramedics I would always begin my lecture on treating burns by asking the class what was the first step they thought they needed to take. Many gave the common answer to all treatment questions - secure the airway; some answered with choose wet or dry dressings depending on the degree and extent of the burns; one would invariably say "pain control" or some other thing that was way down on the list.
The correct answer, however, was "First, put out the fire"!

Agree. I don't have a .32 ACP, but I think the same can be said for .380 ACP HP's not expanding....so I carry FMJ's in my Kahr P380.
