Stopping Power of .45 Compared to 9mm

Not surprisingly, there's hardly a law enforcement agency or miltary organization on earth that uses the .38 Super, whereas the venerable .45 ACP continues to be widely used after about a century. The Super is also uncommon in the civilian shooting world.

Excluding Mexico (from what I hear) of course.

LE and the military probably stay away from 38 Super because it is rare. The data I've seen put the better loads somewhere between 9mm +P and 357 Magnum. Not a rifle bullet, but nothing to sneeze at either. And I'm not sure where you call home, but I wouldn't call 357 Sig all that common either. Around my area, it's as rare as 38 Super itself.

Speaking of 357 Magnum, it's interesting that few people challenge it's stopping power (ie, 125 grain), but minum 200 fps or so (124 grain 9mm +P) and it suddenly becomes a weak piece of crap :D .

How 200 fps makes such a massive difference I'd love to know :) . For the record, I'm not comparing 9mm to 357 Mag. I'll always prefer 357 Mag for its versatility.
 
There are a number of .45's and .357's suitable for carry purposes, and both are far from "marginally effective". Both are rated approximately 90% in one-shot stopping power, according to years of case studies done by military, law enforcement and civilian firearms specialists, ballistic experts etc.

.45's and .357's aren't "anemic and underpowered" in any way, shape or form. I was at the range a couple weeks ago, sitting on a bench about 12 feet behind three guys who were shooting .357's. Every time one of them shot, I could feel the shock wave all the way back where I was sitting.

Uhm, as Evan Marshall, who collected that data on the .357 and the .45 ACP has oft stated, if he were going to be involved in a fight for his life, his choice would be a rifle.

His assessment of one shot stops does not preclude that such handgun rounds be considered fired for one shot at an irate felon, but fired until the weapon is empty, preferably while retreating to the rifle he keeps in his car.
 
The "the .45 won't shrink" argument does seem to have some truth. Anything that would swage a .452 bullet down to .355 would stop it.

And again, in the fluid, pliant mass of the human body, the a streamlined .45 ACP ball round will not cut a .452 hole, which is why Uncle Jeff preferred 230-grain FLAT POINTS which cut a wider path than the woefully ineffecient FMJ round nose.

At the same time, does it matter?
Two holes in your chest cavity are two holes in your chest cavity. They'll probably destroy all kinds of vital stuff and seriously decrease your attacker's ability to keep attacking you.
The argument between a .45 bullet vs. a 9mm bullet is like saying getting stabbed with a stiletto isn't as fatal as getting stabbed with a Kabar.
Either way, you're just as hurt.

+1. Truth spoken.

You shouldn't go by what you hear, because your source is wrong. The primary sidearm of the Mexican military is the Beretta 92 in 9mm.

So I repeat--virtually no law enforcement agency or military organization in the world uses the .38 Super. The cartridge was first introduced about 80 years ago, and has never caught on anywhere.

The SIG-Sauer P229 chambered in .357 SIG is the official sidearm of the North Carolina State Highway Patrol, so the .357 SIG is a lot more common around your area than you're aware of. :p
 
"Stopping power" is a lot like "horsepower", both essentially meaningless marketing terms that are functions of any number of other parameters.

The very individual nature of "in the wild" shooting incidents makes any useful comparisons just about impossible. Instead we have to rely on consistent, reproducible experimental data, and those data suggest the major pistol calibers are much closer to each other than many people really want to believe.

If everyone I meet tells me that it's hot outside, but a scientist tells me that "according to his data" it must be cool outside, I'm certainly inclined to dismiss the scientist.

of course since the 38 super and .357 sig are ballistic twins. I would argue that the only reason its not in wide use today is the need to have somthing new fangled.Because a 124 golddot going 1400 fps from my .38 super is just as viable defence round as any other today.

actually those 90% figures are distorted as they don't take into account the perps predisposition.

You don't want to go down that path, it's always ridiculous.
For example, I could easily say that if everyone I meet tells me the moon is a ball of green cheese and a scientist tells me that according to his data it's a ball of dust and rock, I'm going to believe the scientist. Insert any number of things that go either way.


Having said that, I'll insult a man's god while standing in his church before I insult his caliber of choice.
 
The problem with this is that it can't really ever be an exact science.
There is no way to establish a control group to test effectiveness of defensive ammunition (thank God!).

So about all we have are studies that, while better than nothing, still can't really ever paint a complete picture. This leads to the ongoing argument.
 
"There is no way to establish a control group to test effectiveness of defensive ammunition (thank God!)."

Yes there is, use it hunting. It would take a large group using the same ammo, but you would have something closer to the real world. Or, just test your best theory, and come back with it.

I plan on doing this with my bear defense gun. I am told that a large pig has the same bone structure, including the skull. We are planning a "large" pig roast this summer, just so I can test my theory.

.38 super requires larger frame guns (wider grips as well) compared to .357 sig.

I think that plus the markeing by SIG made
it more acceptable than
.38 super.

And even after all these
efforts .357 SIG is not
overtaking (and not
even coming close) to
9, 40, 45

It just just hard to break in between those 3. I cannot imagine
any round that would break in now.
I think .22 reed express, Five-Seven FN,
7.62x25 tokarev are the only 'types' of rounds that if offered at the price of .40 in modern platforms (meaning glock/beretta/sig/CZ-75/XD/Ruger) -- would actually be given consideration from
LE/civ and even military

Dream on!

Ballistic twins?!

A 115 grain .357 SIG bullet is rated at 1564 FPS and 624 ft. lbs. of energy, while a 115 grain .38 Super is rated at 1395 FPS and 497 ft. lbs. of energy.

A SIGNIFICANT advantage for the ballistically superior .357 SIG.

The .38 Super simply never caught on anywhere in the world, even though it has been around for about 80 years now.

While the clearly superior .357 SIG, which wasn't developed until 1994, is the standard issue cartridge of the U.S. Secret Service, the Federal Protective Service, the Federal Air Marshals, the North Carolina State Highway Patrol, the Virginia State Police, the Texas Department of Public Safety, the Tennessee Highway Patrol, and the Canadian Forces Joint Task Force 2 special ops counter-terrorism unit---just to name a few.

In only about 14 short years, the .357 SIG has gained noticeable support in the law enforcement community nationwide.

Not many handgun manufacturers bother producing the .38 Super anymore, and those that do only produce a small number.

Whereas .357 SIGs are being produced in substantial numbers by SIG-Sauer, Springfield Armory, Smith & Wesson, Glock, Beretta, Heckler & Koch etc.
 
No. I was referring to the 9mm and other "weaker" calibers (.38, .380, .25, .22, etc...).

That’s my point, the standard 45 and the “standard” 40S&W load are both weaker than the standard NATO 9mm load, which is the standard load every where else in the world except the United States, because of SAAMI rules.

Do the math.

If the differences are so small, then why did police agencies across the nation trade in their 9mm pistols in favor of pistols that launch a more powerful caliber?

Many folks still wonder why. Probably why many are going “BACK” to the 9mm, one example was San Diego PD IIRC.

Although many are staying with the 40. I am not a fan of the 40. But nothing wrong with it either. I personally see no advantage of it over either the 45 or the 9mm.

So I ask you, what other conclusion can one draw other than the notion that the .45 is just too powerful for some folks?

Now I agree with you that "it's just a .45"....I don't see what the big deal is either....but we must remember that there ARE some shooters here who ARE weaker or disabled or otherwise compromised.

SIGH! Now you seem to be confusing recoil with power.

My 20 yr old daughter prefers a 1911 in 45acp because I can get the weapon to fit her hands properly. She is 4'10'' and about 105 lbs. Yet don't get in a shooting contest with her. Both my Daughters started shooting at the age of 8. Both prefer the 45acp. My oldest who stands 5'6'' prefers the Glock 30. Only a real yahoo thinks it is about recoil.

I qualified Expert with the 45acp for my 10 years in the Marine Corps. But whether I have one of my 9 1911's in 45acp or one of my High Powers in 9mm, doesn't matter to me.

In my appropriate Milt Sparks VMII holster with notable exception will either be a Colt Gunsite Pistol, government length of course, or my factory chromed lightly tweaked by Novak, Browning High Power. does that sound like I prefer one cartridge over the other?

The fact that this never ending debate has become increasingly esoteric only underscores, in my opinion, just how similar the major handgun rounds are in their terminal performance. Just about all the quality hollow point designs show surprisingly similar penetration and expansion results among the various calibers. With this lack of gross empirical differences, people instead delve into technical minutiae and anecdotes in an effort to prove the superiority of one over another. It is at once both frustrating and amusing.

BINGO!

If you think 45 is better than 9 or 40 is better than 45, or 9 is better, you really don’t understand the question.

I am the weapon. The gun/caliber is the tool. And I do know how to use my tools.

But if the expansion is similar, and if the penetration is similar, why not go with the heavier bullet delivering more ft. lbs. of energy?

Exactly my point. The 45acp has less energy than the 9mm. Damn facts keep getting in the way again.

NATO STANDARD 45ACP 230gr FMC @ 850fps = muzzle energy of 369 ft/lbs
NATO STANDARD 9mm 124gr FMC @ 1250fps = muzzle energy of 430 ft/lbs
(source: Winchester ammunition ballistics page)

Not to mention the fact that you cannot rely upon expansion as it's never guaranteed.
As the old saying goes....a 9mm might expand, but a .45 will never shrink.

Just as you cannot depend on the penetration of the 45acp. The 9mm will penetrate. No less luminaries and champions of the 45acp as LtCol Cooper and Chuck Taylor have repeatedly stated that the 45 suffers from poor penetration.

The 9mm for 80 years the criticism has been over penetration. The non magnum caliber that is most likely to penetrate a Bullet proof vest is the 9mm, not 45acp.

Why not carry a .357 instead if your goal is delivering energy foot-pounds?

BINGO, again.

No dept has ever dropped the 357 Magnum for lack of stopping power. Only lack of fire power. The police felt they needed more rounds, that and speed of reloading (another I need more rounds function) is/was the specifically stated reason for going to bottom feeders.

In fact it is a reason many use the very hot 9mm’s or go to the 357SIG. Which is a 9mm on steroids.

Massad Ayoob - "The Gun Digest Book of Combat Handgunnery 6th edition" page 253.

I don't think Mas would suggest a .22 over a .45 but I do think it's interesting that weapons choice is the last thing listed in priority.

Reliability should be the first reason. Second reason should be fit, to the individual shooter.

Caliber should be the last choice if one still thinks that is still important.

Seems pretty reasonable coming from an career police office, champion target shooter, author and expert witness. I think I'll stick to his suggestion rather than get wrapped up in pointless debate.

Well…..a career part time police officer. I have met the man, an like him. But he doesn’t walk on water either. A lot of good idea’s but many are a bit off the mark too.

The .45 ACP has superior stopping power to the .38 Super, regardless of your above post.

Just cause you and others say it, don’t make it true.

Not surprisingly, there's hardly a law enforcement agency or military organization on earth that uses the .38 Super, whereas the venerable .45 ACP continues to be widely used after about a century. The Super is also uncommon in the civilian shooting world.

Absolutely, because the NATO standard 9mm can and does most every thing the 38 super does in a smaller package. The super’s strength, is that it was designed to work in the 1911 size weapon. And as USPSA/IPSC has shown, it is very effective at out competing the 45 on the competition field. I wonder if it is that recoil thing’y?

The 38 super shines when used by a skilled reloader. It is an enthusiasts cartridge. And fine when used with quality bullets as a defense load. Just not generally used for that.

I should stop being sucked into these things with folks who are unprejudiced by facts.

If folks put as much energy in maintaining and cleaning their weapons as arguing this useless BS, shooting would be advancing much faster than it does.

Go figure.

This is one very poor argument....
After all, there's no way that humans could know the composition of the moon without direct firsthand knowledge.
But there are plenty of folks who DO have direct firsthand knowledge of the effectiveness of various calibers.
Many folks have actually used the .45 against other humans and can testify to its effectiveness without an once of speculation....just as there are many who can testify to the 9mm's lack of effectiveness.
Among humans shared experience is what establishes reputation.....and the 9mm has a rather poor one.
 
That’s my point, the standard 45 and the “standard” 40S&W load are both weaker than the standard NATO 9mm load, which is the standard load every where else in the world except the United States, because of SAAMI rules.
Give us some sites with hard numbers to back this statement up please.

Many folks still wonder why. Probably why many are going “BACK” to the 9mm, one example was San Diego PD IIRC.
I guess it depends upon what you call "MANY".....I'n my opinion, there are very few going back to the 9mm....and I'll bet that they will not stay with it for long.

I personally see no advantage of it over either the 45 or the 9mm.
.40 vs the 9mm= the .40 offers a bigger heavier slug with similar or greater velocities, delivering as much or more energy as the 9mm, and with nearly the same magazine capacity.
.40 vs the .45= the .40 offers nearly as large and heavy a slug, moving faster, delivering comparable energy levels, and offering more in the magazine.

SIGH! Now you seem to be confusing recoil with power.
Attack of the "word nazi" :rolleyes:....

Good for your daughters!
But anyone who does not believe that recoil factors in to one's preference in firearms really has his head in the sand.
I think that most of us here have at one time fired a light-weight snubbie with hot .357 mag rounds....and I doubt that most here will agree that it was fun.

If you think 45 is better than 9 or 40 is better than 45, or 9 is better, you really don’t understand the question.

I am the weapon. The gun/caliber is the tool. And I do know how to use my tools.
But there is simply no denying that some tools are better than others.
And it's not just 100% about shot placement and what you feel comfortable with.
This is something we say to comfort those who can't shoot the more powerful calibers.
If caliber did not matter, everyone would be carrying a .22 pistol.
 
Attack of the "word nazi"

You don’t understand the difference between recoil and power, and call me a NAZI! First, I can’t be a NAZI, I am not a socialist, and I do know the difference between recoil and Power.

Good for your daughters!

I will say you are obstinate. That hot 357mag out of a snub frankly isn’t much more powerful than one of the hot 38spl’s out of a 4”+ tube. Once again, recoil does not equal power. In your example recoil is a function of the weight of the launch platform. In some weapons the recoil is or isn’t tamed based on design. Sheeeshh.

But there is simply no denying that some tools are better than others.
And it's not just 100% about shot placement and what you feel comfortable with.
This is something we say to comfort those who can't shoot the more powerful calibers.
If caliber did not matter, everyone would be carrying a .22 pistol.

You still seem to think there is a relationship between recoil and stopping power. There isn’t.

As to tools to stop people, virtually all fighting rifle calibers, are vastly superior to all handgun fighting calibers. And ALL handgun calibers are poor in regards to stopping power.

None are so blind as those who refuse to see.

Good night and good bye.

Go figure.

That's not really the same because game animals don't necessarily react like a human being would. A deer isn't pointing a Glock at you and it's not going to attack you if your round fails to stop. It would probably be gone before you could even get a second accurate shot off.
To hunt big pig's I'd want something that would penetrate as far as possible. Expansion would be fine but kind of secondary.
With defense ammo, expansion is a big deal to me. I want the bullets to stop and not travel through the attacker and down the block, hitting anything in their path. My biggest reason for using JHP ammo for defense is that I see it as a social responsibility. I don't want to put other people at risk.

easyg said:

It's not so much that it doesn't matter at all as much as it doesn't matter after you have enough power.
I've seen .22 LR JHP ammo bounce off a car side window without damaging it and flatten out and fail to penetrate on the shoulder blade of a pretty small animal. I don't consider a .22 a good thing to get shot at with but I'd be worried that it wouldn't penetrate through something like the sternum or a rib.
But with LRN bullets it would stand a better chance and it also shouldn't have any problem penetrating soft tissue.
If I carried a .22, I'd learn to shoot it fast and well (easier to do when you can still get 500 rounds for under $20), carry something like CCI mini-mag solids, and plan to fire 3-5 round "bursts" and probably keep shooting until empty.
Not the best choice but it's better than a sharp stick for those who truly can't handle much recoil (IMO that argument doesn't fly with 9mm vs .40 vs .45 because that's too wide open to how different guns fit the shooter's hand).
 
My point of the pig is to test a bear defense load, an example.

This thread is about performance of a specific caliber, which it has been implied that there is more to a caliber, including bullet choice and shoot ability. I like to float around the world of hypotheticals like anyone else. But, when someones says you can't test your theory, that just sounds like quiting. I only offered a possible method of testing a theory.

Of course a deer doesn't react like a wimpy human, however if you find that ball ammo kills very slowly, while a well designed hp is significantly better. While a barnes bullet bleeds them much quicker; well, there you go. When it comes to hunting, all things being as equal as possible, a bigger hole incapacitates an animal faster.

As far as putting other people at risk, I agree. I don't have my bear defense load loaded at home.
 
Chieftain writes an entire post with supportable facts and hard mathematical/scienticically backed data...

And easyg just goes "Nuh uh."

Chieftain, thank you for your contribution. I'm sorry you got bit on the torso by a troll.
 
Nuh uh

I remember in elementary school me and this kid were always arguing over which was the faster car, a Lamborghini Countach or a Ferrari Testarossa (did I grow up in the 80s or what?). He was emphatic that it was the Lamborghini, and when I brought in a book about super cars that showed the Ferrari had a higher top speed his only response was "well a book can lie". Pretty much all Internet debates remind me of that. :)
