I own both ,like both but love 40sw.
Not claiming which is “better” or “superior” ballistically, but I just like the 9mm much better now because it is easier on my arthritic wrists and on my wallet (at least until recently).
Besides, I prefer a light weight sub-compact handgun for my CCW nowadays. 124gr 9mm +P rounds that I carry will still do the job defending myself or my family.
I guess it will depend on the purpose.
For HD I definitely prefer the 45, don't see firing tons of rounds in that situation, prefer a bit more impact and a bigger hole, and lastly rounds that deliver results while still being subsonic and not blow out my ears in the house. Also for HD a full size gun is not an issue, and I really like the way the 21SF fits my hand, compared to the 17. I don't feel much difference in handling SD +P rounds with the 21SF compared to the 17, the 45 +P has a bit more push to it, but easily managed in the 21SF.
For carry a 9mm makes more sense, smaller & lighter. Also it seems 9mm retains more velocity with a shorter barrel and most SD rounds still does really well with a shorter barrel. With the 45 it seems the SD round results are a bit more hit and miss, looking at various tests done it seems the shorter barrel impacts the ability to expand on 45s more than 9s.
For LEO or other security services I do see the additional round capacity to be much more relevant than for home defense or most civilian CCW purposes (at least if you carry a spare mag).
For general target shooting and other fun activities I can see the attraction of the 9 with less weight to carry and also supposedly cheaper rounds (though that has not really been true this year).
Since my primary purpose is HD I voted 45.

Neither! I appendix carry a S&W 500.
Same boat for me.. been shooting 1911's for over 40 years. Currently in 10mm most often.
I can shoot the 1911 in ten mm faster than any glock. I just can.
I chose 45. But there are times when it is too hot and miserably humid to carry a larger gun, so I will carry my 3914NL.
But based on 20 years working RHD, I saw miscreants shot with just about everything. The ones hit in a vital spot, with any caliber were DRT.
But we also noticed that those hit with 357 Magnum, 45 and 00 Buck always went to the morgue. Many hit with other smaller calibers were saved by medical intervention.
I have nothing against 9mm. I prefer 147 grain RA9T when I do carry a nine. And when I can no longer control a 45 to get fast accurate hits, I will carry a 9mm. Regards 18DAI
Again, depending on bullet choice, you arent getting a bigger hole or much more impact, depending on what that means to you. A 230gr/45 ball produces about 400#, 195pf (think momentum), but a less than 45cal hole.
A 124gr /9mm +p jhp produces about 400ft#, 147pf, but will produce a near 60cal hole. So really, not a huge diff. The bullet choice in 9mm is more important but hitting harder, not really. I can shoot anything but I have a ton of confidence in a full size, steel 1911. If stuck with ball ammo, it is what I would choose to carry, just double up on your spare mags.
In my case I use full size 9 and 45 Glocks (17 vs 21SF) with 4.6" barrels, both of which I have loaded with HST +P. For the 9 (124gr) it has 396 ft lbs and it expands to about .64" to .66".
For the 45 (230gr) it has 461 ft lbs and it expands to about .84" to .86".
Expansion for both is pretty much the norm if you look at various tests, and great expansion for both (thus my pick for both as SD ammo).
Seemingly what people forget is that you use the surface area of the expanded bullet to determine wound cavity. For practical purposes you can use it as a cylinder or circle from expansion.
For the 9 the surface area of the cavity is around 0.34 sq in.
For the 45 it is around 0.57 sq in. Basically 2/3s larger.
Which explains why the 45 with more energy and momentum don't penetrate as deep as the 9 when people do gel tests, as it is making a significantly larger hole in the target.
I find shooting the 45 actually a little easier than the 9 with the SD +P ammo, the type of recoil and bigger grip seem to work better. My biggest issue was getting used to the Glock triggers, but figured that out after a number of range trips and using a minus connector to have more consistent pull. The only time the 9 is easier to manage for me is shooting one handed with my left hand. I'm definitely not a competition shooter, but at least proficient with either one.
Today I'm carrying a full size 1911. 7+1 230gr HST and two spare magazines. Yesterday was a G26 with 12+1 147gr HST and a spare G17 magazine.
I'm completely confident in both with a slight preference for .45 ACP. I also prefer the steel 1911 for longer shots and the capacity of the 9mm when traveling to larger cities.
The .45 ACP started off the winner in the early 20th century.
The 9mm surpassed the .45 ACP in the 80s with higher capacity mags & +p+ ammo.
A couple decades later the .45 ACP got increased its capacity and induldged in +p ammo, reclaiming the lead.
I will take a Glock 21 or an FNX-45 with Underwood 185 +p ammo over any 9mm handgun/ammo combination.
With lower quality or ball ammo: 45 hands down.
With HST or similar hollow points I'll take any service caliber.
Capacity is a big plus with the communist stupidity going on in big cities these days.
I have seen a lot of people walking around with 5 or more 9mm scars on their chests than 45 acp. So 9mm in my opinion does not stop a threat quickly.
Here in wisconsin with heavy winter coats and leather jackets and a lot of the inner city folks at 300 to 400 pounds. Its a lot different than some mythical 100 pound cheerleaders dropping due to a hangnail injury.
The local gang members and car jackers resemble more a group of grizzly bears .
10mm is a beast!
10mm is not a beast. But for a handgun round it works quite well. I load 150 to 180 grain bullets and use power pistol powder. For defense its all hornady critical duty.
10mm is fast heavy .40 cal just as 357 sig is very fast 9mm in practice.
The folks that tell me 9mm is as good as everything else. That no difference exists between handgun rounds seem to also say that 357 sig and ten mm are far too powerful to shoot well or quickly. So its far more powerful when you dont like it. But its the same otherwise. Right
I got over 700 ft-lbs of muzzle energy with Underwood’s 200 grain XTPs and they stay within the FBI penetration standards.
That is beast!
