Caliber effectiveness

A GSW that cuts the abdominal aorta will likely be fatal. Soon. 9mm or 45.
Yes, BUT will it be fast enough to save lives? Study the 1986 FBI Miami shootout for one possible result. (where lives were lost after the bad guy took a fatal wound, but before he was stopped)

But if it hits the rib where it joins the spine,will the greater area of a 45 translate to more temporary "stun" delivered from the rib to the spine?

Again, I'll point to the 96 Miami shootout. One of the agents took a .223 to the neck. Not the spine, but close enough that the shock damage to the spine left him paralysed and unable to do anything during the fight.

Every situation is different, and there's no guarantee and what worked one way in one shooting might not do the same in another.

I understand and agree.

I'm not trying to be a smart alec.but ts just true that on one day,a Bersa 22 might make a one stop shot,and on another day,I knew a Man who was a Medic on the Korean War.He stepped on a mine.It blew off one foot and the other leg at the knee. He crawled to keep tending wounded.

What,IMO,is just unavailable data,is the first 10 seconds after a hit. The first three seconds after a hit. I get it,one shot stop s illusion.

I accept and have heard most of the "doctrine"

I'm not arguing.

I wonder if I'd get the same response if I asked the same question,but instead of a Shield,45 vs 9 mm,I asked 1911,45 vs 9mm. Single stack,both cases.

I actually tend to make my own decisions and take responsibility for them.
I don't need to be told which gun to buy..I can handle it.

I'm illustrating that after yet another 9mm vs 45 ACP thread, what is new?

If I'm carrying either,I have a gun.An adequate gun. Maybe. Hits count.Maybe. And Life is uncertain.
 
The AK was designed and purpose built to provide a large volume of suppressive fire in support of unabated armored attack. As German Blitzkreig tactics changed the operational doctrine of almost every military ....especially the Soviets, the PPsh machine pistol had proved the effectiveness in this type of warfare.

Intermediate cartridge, compact (less obtrusive in an APC), high capacity, select fire.
 
Maybe I was not clear. I'm talking about a 45ACP Shield 2.0 vs a 9 mm Shield 2.0.
The capacity difference is one round.

The 9mm and not for ballistic reasons

-in that small if a gun .40/.45 becomes a bit of a shooting liability IMO. 9mm makes more sense. Even with lots of practice you really need to be on your game with larger calibers in such a small light platform. This matters much less as the platform size increases IMO.

- Capacity. I personally think the difference between 13 and 15 rounds is negligible, 15 vs 17 same. 10 and 12 also fairly negligible. Once, however, you start dropping below ten I think each extra shot starts to matter.


-Weight. You are buying an itty bitty carry gun so size and weight must matter. 9mm is lighter.

-Enjoyment. I find that most folks practice more with guns they have fun with. Will you ENJOY shooting .45 out of a small platform such as this?

At the end of the day it’s almost all software that matters with the hardware being a very distant deciding factor. You can learn to shoot anything well.

At any rate I say 9mm in this package

I have no dog in the caliber fight. I shoot them all.

Found a great video on handgun wounding and the realities of bullet performance.

Not trying to start a caliber war...far from it. Im hoping to put some of the myths we hear repeated endlessly to rest.
Well, 45 posts and not much 'put to bed' on the continuing 'caliber wars'...:rolleyes::eek:

I've watched a few of these types of vids and good info all. Not etched on tablets and brought down from a mountain top but.....take the stuff that makes sense to ya and press on..

I agree, and all points made here are valid. I have one more. Small CC handguns are typically more reliable in 9mm than they are in .45. The physics of that longer fatter cartridge chambering properly play hell with small easily concealed weapons. I have no experience with the shield in .45, they may have mastered reliability in the platform. I know Kahr arms PM, CM, and CWs typically run like a sewing machine in 9mm... not quite so in .45.
 
Interesting video. Interesting comments. I think stinkypete hit upon a significant factor in all this, popularity. Popularity in calibers and capacities has often come from a combination of marketing and actual field data, but the field data, as a whole for a caliber or bullet type, has been a single aggregate CORRELATED with performance that people will assume to be CAUSATIVE. It is not causative because each and every shooting is unique from every other shooting. Nobody can discern, looking at raw data, why X number of people failed to die (or be stopped, or be stopped fast enough) when using whatever is currently the ultimate stopper de jour. This is a significant problem with the one shot stop and similar studies. Far too many variables of the shootings could NOT be controlled for and they often could not be controlled for because the explicit detail needed to control for them was not available. More over, end users took one shot stop to be definitive of bullet performance, despite the fact that many one shot stops were psychological and not physiological (a guy shot in the shoulder or gut and gave up equated to one through the heart and spine and died instantly). However, this type of study is popular because it appears to provide a definitive answer on performance, which in reality it did not do because too many factors were not controlled for by the study.

What we can get from the aggregate data sets are some trends of possible or probable expected performance, if taken with a whole host of assumptive parameters, which we often discard from statement or consideration despite the fact that they are actually critical to the end results we are trying to understand.

So because the end data are not wholly reliable to glean what we want to know, we try to simulate it with a controlled media (ballistics gel) that comes with its own host of assumptions and considerations. While gel use is really cool and let's us "see" how the bullet performs in a uniform media, strangely, human and animal targets are not uniform media and what happens in living targets is not always a match for what happens in ballistics gel. I know what was said in the video about ballistics gel and what happens in the field, but there is no reason to assume that just because it does happen in gel that it will happen in the field. Again, lots of variables involved. Ballistics gel, for lack of a better description, is a sort of the ideal of what will happen and it really seems to tell us more about what happens to the bullet than what happens to actual living tissue. These ballistic gel results, like one shot stop studies, tend to narrow focus on a very select set of parameters, excluding all else, from which the data crunchers and end users tend to drawn conclusions that simply may not happen in the real world.

Are these helpful? Sure. Are they definitive? No. Do they resolve caliber superiority claims? No, not except for more extreme comparisons where the answer was already pretty obvious (like the .17 hmr/.45-70 comparison noted above).

I necropsy a bunch of the hogs that I shoot to see how bullets perform. It is interesting to see the same bullet model/load fired from the same gun perform in very different manners when hitting hogs. No doubt this is because not all of the hogs are hit in the exact same trajectory at the exact same distance (velocity), and not all hogs are exactly the same in composition (sort of like humans). One thing I have noticed to be true is that the consistently symmetrical, perfect, and pretty expanded bullets you see in the gel tests are very often not what I recover in the field which are often fragmented or lopsided and look almost nothing like their ballistics gel counterparts. And here I make an assumption, but if the bullets are coming out looking very different, then how they performed in animal tissue is also likely different that what is shown in the gel tests.

8 was enough because the pistols were used for shooting deserters and trouble makers, not fighting, historical doctrine.

The Luger was not adopted by the German and Swiss militaries for shooting deserters and trouble makers. Neither was the P38. They were adopted, like the 1911, as a combat weapons.

Yes, there are but we are talking about Germans in WWI and WWII. I believe only officers carried pistols in the German Army.

Not quite right. Officers, as was common in the US military often had pistols and not long guns issued to them, but officers were not the only people that carried them. They were issued to NCOs, air crews, machinegunners, etc. It was not standard for the average enlisted army soldier to be given a side arm, much like in the US military, where the 1911 was not adopted or used primarily for shooting deserters and troublemakers.
 
None of this helps me decide between a 7 rd 45 ACP Shield and an 8 rd 9mm Shield.

And no,telling me to choose a different gun is not the point.

Between those two models, does either of them carry/conceal more easily for you as you go about all of your normal daily/evening activities? If so, then that difference might be of importance to you in your choice when it comes to concealment.

Do you shoot either of them better, especially under demanding and stressful conditions? For example, have you used both of them in any IDPA events, and if so, did either allow you to noticeably "do better" when it came to handling, manipulation, shooting and scoring?

If they both "carry" equally well, and you feel you shoot both of them "identically well", then choosing one is up to using whatever other criteria you think may matter ... while accepting that the totality of any circumstances and situations you may encounter might render your reasoning moot.

I've invested a fair number of years carrying and using both, as both a working cop and a longtime LE firearms trainer. While I fully understand that a heavier .45ACP bullet might have some additional momentum that's useful in knocking over a lightweight plastic-clad wooden bowling pin, or a lightweight steel plate ... and some JHP's might expand under ideal conditions to a couple tenth's of an inch more than another JHP ... I don't pretend that a full-size adult's anatomy is in any way similar in complexity, size and full body weight to a bowling pin or small steel plate.

Some days I prefer to carry one of my 7, 8 or 10rd 9's (G26, 3913, CS9, SW999c), and some days I prefer to carry one of my 6rd .45's (CS45 or original 4513TSW) ... or one of my 7 or 9rd .40's.

Whenever someone for whom I've been responsible to help train asks me for a suggestion, I typically tell them to either use whatever they've been given (issued), or have optionally chosen to use (for reasons of their own informed choice), as long as they make sure they can run it well, controllably and accurately, employ sound tactics in its use and use if effectively for the circumstances. If they want to imbue their choice with some "talismanic" properties that makes them feel better about themselves and their choice, that's not my business.

Choose as you will, but be prepared to live with the responsibility of accepting the consequences of your decision. ;)

It's just a handgun.
 
..like the .17 hmr/.45-70 comparison ...

While the .17/.45-70 comparison is illustrative, I prefer .22-250/.45-70 for the comparison. The reasons being, I have both, and have personal experience with them, and I don't have a .17.

And, I looked things up a while back, and the .22-250 and the .45-70 can be loaded to IDENTICAL energy levels. The exact same number of ft/lbs.

I like to use this example for those who tout energy (ft/lbs) as being the deciding, or most important factor in performance or "stopping power".

Say an irate bear decides you are his next chew toy, or a peeved buffalo wants you underfoot, and is approaching at speed. You have time for one well aimed shot. There are two rifles within reach equal in ft/lbs of energy. One is a .22-250, the other a .45-70. Which one do you grab??

Personally, if I were about to be attacked by a block of ballistic gel run amok, I might pick the .22-250. Anything else, I'd be grabbing the .45-70 :D

Energy (ft/lbs) ALONE isn't the full story, or the most important part.

Absolutely. ;)

It's just that some folks like to use calculated ME for a way to support their favorite confirmation bias when it comes to calibers. :)

For some it also seems to remove the onus of accepting their degree of responsibility to choose and act effectively for the circumstances, and be able to themselves perform adequately to the needs of the moment. Blame the caliber is a long popular reaction and response, sad to say.
 
At about 7:00 he addressed the most important issues in the caliber wars.

First, there is not enough velocity and energy to create hydrostatic displacement that is capable of tearing apart a person's liver or arteries with just a close hit. Just like gel, exactly like gel, you get a stretch cavity, and unlike gel, human tissues are fibrous, tough, flexible. Shooting through wet paper isn't going to show a cavity because you couldn't possibly tear all of those fibers. The only thing that a pistol can do is make a person bleed, break bones or nerve conduction. You can sometimes get a hammer sort of effect that will hurt the target badly enough to psychologically disable him from pain, but without a damaging shot, you won't physically disable him.

The massive kinetic energy carried by big guns isn't being used to disable the human target. Just like any other bullet it will break or tear, and tearing and breaking happen pretty much the same with any bullet of sufficient weight, momentum and makeup. A .45 bore size will drill a hole that is almost identical to a .35 bore size. If you make either of them heavier. fooling around with velocity and weight figures to gain some mathematical advantage just for an argument is pointless. If a big bullet gets full penetration, it has done little, maybe no extra physical damage to the human target.

Your goal, as a shooter, is to tear a large bleeding hole through a guy's tissues. something that will tear ragged and oversized holes is perfect. That is why we use hollow points, and especially fluted or petaled bullets.It doesn't matter how you get that 1" wide ragged hole through a guy's abdomen, it's going to do about the same thing whether it's a stick or a bullet. It's going to make a hole.

At about 7:00 he makes the very best point ever. It doesn't matter how much energy you are sending into a person and the gel testing proves it. What good is a temporary cavity? All that does is waste energy doing ineffective things. It's useful in that it can bruise a bit, maybe tear up some delicate tissues, and possibly cause more pain, but a temporary cavity the size of a volleyball simply represents a lot of gel being thrown around.

The FBI did everyone a favor by settling on a standard testing and design standard. We have gel, and that gives you a reasonable facsimile of the density of tissues. We can now fire a bullet into this gel and you will know what it can do. You will know that penetration and permanent wound cavity are similar enough to human tissues that it will be a good benchmark.

But that said, gel isn't people, and all you will get is an estimation. It's going to be different for every shot. Shooting through a 6" layer of brisket fat before even reaching the actual meat isn't accurate.


If a 9mm round can get identical penetration and damage path of a .40 then there's no reason to use a .40

I keep harping on the attempted suicide that happened in newton county near here. A boy shot himself through the heart with a super blackhawk in .44 magnum. They repaired the damage to his heart, sewed him up and he survived.

There is a point of diminishing returns on everything. Since a gunfight is chaotic and unpredictable, maybe even involving armored assailants, maybe heavier rounds are called for. For most situations, you can carry a reasonable caliber in a premium round and expect that you will accomplish the goal, a deep ragged hole in a human body, maybe broken bones or damaged organs or arteries.
 
Since a gunfight is chaotic and unpredictable, maybe even involving armored assailants, maybe heavier rounds are called for.

But the premise that supports this rests on a belief that, somehow, your skills are of such a level that multiple armed, armored, determined, and competent attackers can be overcome. There is a point that it is HIGHLY unlikely any of us possess the skill set needed to overcome the situation regardless of equipment. But hey, buying new equipment is fun so lets buy new equipment. Sometimes one has to accept that they are going to struggle if such a battle were to occur, ultimately fall, meet fate as gloriously as one can, and await the Valkyries
 
This scenario of multiple attackers,competent,armored,and well armed...

Seems like a bit of a reach if we are talking about civilian self defense handguns.
You are describing (generally ) confronting a SWAT team.

That generally ,IMO,should be a discussion of making better life choices,not which cartridge to use.
 
It's just that some folks like to use calculated ME for a way to support their favorite confirmation bias when it comes to calibers.

They do in fact. And I have been saying for a very long time that there is more to "wounding capacity" than simple ME (I assume you mean muzzle k/e). I said it earlier with .223 v 45/70, but 44 AMP gave an exact k/e equivalent with .22-250 v 45-70 whereas my example was but a close approximation.

At any rate, there are several factors that come into play as to how effective a bullet will be on target. Bullet construction (as in will it expand), sectional density (barely worth noting in common pistol calibers in regards to SD, but we'll throw it out there), momentum (I know a lot of folks don't like to acknowledge this but it matters to at least some degree), and kinetic energy (we all know this).

Then there are the platform characteristics. Many have made much ado about faster follow-up shots, however a shot timer does not bear out that a full size 9mm pistol is really much faster for follow-up shots than a full-size .40 or .45. I believe my old stats I compiled was 13 rounds of 9mm to 11 rounds of .45. Which will do more damage? Will the extra frontal area and momentum of .45 make up for the 2 fewer rounds? Are two extra rounds of 9mm, despite possibly being not quite as effective by ever so slight a degree, better? The answer: I dunno, I don't think it could ever be measured, and I don't think there would be a statistically relevant difference.

Capacity is where the big boys really lose their advantage IMO. Especially when comparing the almighty American Pie .45acp to 9mm. Also, I believe the follow up shot logic works much better in favor of smaller rounds when comparing CC pistols like the shield.
 
I have no problems in controlling my 9s or 45s. I can hit reliably with all of them.

When I took my CCW course back in 1995 the instructor (during the live fire part of the course) made comment of the sort: "damn, you are the only one shooting groups today". I was using my first Colt Government Model Series 70 45 ACP at that time.

I had no misses at the silhouette targets, so I passed the course.

My Dad was shooting his Colt 380 1908 and he had no misses.

We used to shoot together quite a lot. It pays to practice.
 
I keep harping on the attempted suicide that happened in newton county near here. A boy shot himself through the heart with a super blackhawk in .44 magnum. They repaired the damage to his heart, sewed him up and he survived.

What bullet was used? Bullet construction is just as important as caliber and velocity.
 
What bullet was used?

Yeah,sure,by golly,I can just imagine the article ,news cast,or interview!

Probably only the owner of the Ruger would know.

(Reporter sticks mic in the boy's Father's face)
" So hey,Bud,what load was you using in that 44? ?? H110 and a 240,huh?

Was it one of those scalloped Rem Soft points,or a Gold Dot? Oh,a Laser cast? A Keith? Yeah,uh huh....What charge weigh? Brass? Primer? LOA? Just for my notes.....

So you recon that hard bullet allowed a pericardial tamponade??

Yes,well,now a message from our sponsor......

What bullet did the boy use? Seriously?

Seriously? Why the snarky reply? I asked a serious question. If you are going to tout a caliber as a failure you should at least have some facts. By your response I seriously doubt any of your story. It could have been a Heritage Rough Rider.
 
It was briandg's story,post 52


I did not say any cartridge was a failure.


If a kid attempted suicide with ,as described,a Ruger Super Blackhawk 44 mag,

How would anyone know what bullet was used?

And in the context of the discussion...IMO,briandg did not offer it as a detailed case study,just an example that regardless cartridge,the results of a GSW are unpredictable.The kid may have died had he used a .22.Or a 9mm hardball.

I'm grateful he lived.
