Why the .45 Matters
Strategy Page ^ | Feb 1, 2006

Posted on 02/01/2006 3:42:08 PM PST by John Jorsett

Why do American troops prefer the century old .45 caliber pistol to lighter 9mm models. It’s all about “stopping power.” As far back as 1900, during the fighting against Moslem rebels in the Philippines, there had been complaints of enemy fighters getting shot and continuing to attack. From this experience, the then standard army pistol, a .38 caliber (9.65mm) weapon, was replaced by a .45 caliber (11.4mm) one. In the 1980s, the .45 was in turn replaced by a 9mm pistol. There were a lot of complaints about that, but 90 years of experience demonstrated that you should not depend on a pistol in the heat of combat. But that was largely European experience, in major wars. In these conditions, pistols were rarely used in desperate battles. The fighting in Iraq reminded everyone that, especially in urban combat, a pistol was still an essential weapon. Going into buildings, troops would often prefer to have one or two guys holding pistols, as these could get into action faster if you were in cramped and crowded conditions. At close range, you didn’t want someone with a gun, or a knife, to require a second shot. And at ranges measured in a few feet, you couldn’t miss. If the enemy was amped up, you wanted to take him down with one shot, because there might not be time for a second. Many police SWAT teams have stayed with the .45 for the same reason.

The M1911 was better at stopping people, and that was mainly due to the size of the bullet. Technically, the “hitting power” of a bullet is determined by the bullet weight and velocity, and is measured in joules. The widely used 9mm Parabellum generated 583 joules, the Russian 7.62mm Tokarev (mainly used to execute cowardly soldiers, POWs or uncooperative civilians) produced 499 joules, while the .45 (11.4mm) only came up with 450 joules. But there's a major problem in just using joules, and that is how much of that energy is actually applied to the person being hit. A smaller, faster bullet has a tendency to just go through someone. This does damage, often fatal damage, but if often does not slow down a highly energized soldier. A larger bullet, especially a blunt one, will be more effective at "stopping" someone. Thus the popularity of the .45 caliber pistol round. Although it has less energy than the 9mm round (450 joules compared to 583), those who have used both insist that the .45 is far more effective than the smaller and faster 9mm. Part of this has to do with the fact that the .45 (11.4mm) bullet hits with a 60 percent larger (as seen head on) area, thus it applied more of that energy to the target. This explains the greater likelihood of the .45 caliber bullet "knocking down" whoever it hits. The same physics applies to rifle bullets (although they tend to have pointy tips, unlike the blunter ones for pistol pullets.) A 7.62mm bullet is 88 percent larger (head on) than a 5.56mm one.

Even before the Department of Defense decided to switch back to the .45, SOCOM (Special Operations Command) and the U.S. Marine Corps went and got .45 caliber pistols for use as an “alternative” to the standard 9mm M9. SOCOM was never happy with the 9mm's pistol's stopping power, even in the very limited scenarios, such as terrorist hostage rescue, where they can legally use 9mm hollow-point ammunition for increased effectiveness. SOCOM went out and developed the HK Mark23 Mod 0 SOCOM "offensive" handgun weapons system. This weapon, based on a popular H&K design, is 1.53 inches wide, 5.9 inches high and 9.65 inches long. It weighs 2.42 pounds empty and uses ten or twelve round magazines. The original M1911 is 8.25 inches long, 5.25 inches high, 1.5 inches wide and weighs 2.44 pounds empty (add .4 pounds for a loaded, seven round, magazine). Some 2.7 million M1911s have been manufactured so far, 1.9 million of them during World War II. Some 650,000 of the new U.S. .45 caliber pistols are expected to be manufactured initially.

The U.S. Marine Corps have been using M1911s rebuilt from the many old ones turned in when everyone switched to the M9. But this supply is running out, and the marines have been eager to see the 9mm M9 pistol replaced with a new .45 caliber model. Some marines (and other troops) buy these newer .45 caliber weapons with their own money. Most American combat units tolerate troops bringing in some additional weapons, especially pistols. Some troops have been buying 10mm pistols, seeing this as a nice cross between the lighter weight of the M9 (2.55 pounds versus three for the .45) and the greater stopping power of the 11.4mm M1911 bullet. But there are new .45 models that weigh as much as the M9, carry more bullets (10) and are easier to repair than the M1911.

The SOCOM Mk 23 may not be a prime candidate for the new standard pistol. That’s because the Mk 23 is a large weapon. A new “standard .45” will be used by a wide variety of troops, including women (who have smaller hands.) It is possible to make smaller .45s. One of the smallest currently available is the Glock Model 37. This .45 caliber pistol is 7.32 inches long, 5.51 inches high and 1.18 inches wide. It’s 1.63 pounds empty, and 2.22 pounds with a ten round magazine. Glock began making .45 caliber pistols in the early 1990s, and has steadily improved that design. There are smaller .45s than these Glocks, but none that are as sturdy and reliable. So it is possible to get a smaller .45 design that will be as robust as the original M1911.

Comparing the 9mm Luger to the old .38 Colt cartidge is not really fair. The 9mm produces over twice the energy.

Using best bullets the difference between the 9mm and .45 is not nearly as great as everyone seems to know. Still the .45 is a little better and no reason not to use the best.

On the other hand, the large mag capacity is also an advantage of the 9.

One reason the so called stopping power of the 9 is not evident is because they use ball ammunition and it does not expand and give take advantage of the velocity. Another reason is the 9 just sucks. Give me a .45 any day, or a .44 special. I love the .44 special but of course you can only get it in a wheel gun but still it is a good round for stopping something in it's tracks. Long live the 1911 and all it's clones!

I'm not quite sure how many long guns I own.
But I only own one pistol, a 1911 .45. For me, nothing else is needed.

Ehhh..... what happened to Foot-Pounds?

New tactic - you want to stop the enemy fast - hit him in the joules.

A couple of notes - first, that the Geneva Convention requirements for full metal jackets might be met by certain law enforcement ammunition that is both fully jacketed AND hollow-pointed. Interesting stuff. Second, that the real effectiveness of the .45 (or any other bullet) is measured by how much energy it leaves in the target and how much shock and tissue displacement result from this. A monster bullet that overpenetrates has awesome numbers but less than awesome effectiveness. Third, that the 10mm (and another popular caliber, the .357 SiG) suffer more from this latter defect than the .45 because they are faster; slow, wide, and heavy seems optimal in stopping power at short ranges and where the target is not wearing body armor. Personally I find the 10mm just a bit heavy on the recoil side for CQB but then I'm not a very big guy.

Every hunter knows perfectly well that one tunes one's bullet and charge to fit the game one is after. The self defense community sometimes seems to forget this in reaching for numbers that do not always translate to superior performance. I like the .45 because it's optimized for the human body - that sounds awful, but if it's him or me I want something tuned to him.

I liked the grease gun too, I could put 15 rounds on a bull at 15 yards firing full auto(all right one or two rounds were out but so what!).

I remember many chopper pilots with our Cav. unit in Nam would choose the .45 over the .38 though it was more bulky under their chicken vests. We never doubted it could "stop an oncoming freight train".

A lesser known but quite capable .45 handgun. The Mauser M2 is built by SIG and designed with concealed carry in mind.

I resent that...
I carried{and still do} Carry a 92FS Berreta. I found the gun to be reliable, sturdy and very manly.
A gun is a tool, it depends on who is using it.
I have a Colt Commander. It is a good pistol. But I feel better with 15 rounds than 8.
And it is not a girly pistol.so there..........

I can imagine the recoil from a smaller ligher .45 for women.

It's that darn metric system again.

Joule (energy or work) = applied force of one Newton moving one meter

Newtons (force) = force required to accelerate 1 kilogram one meter

----

As far as I'm concerned when you need to know what it takes to put a six foot man six feet under, foot-pounds just seems to make a lot more sense.

This debate has been on-going since the M9 replaced the M1911A.

I just got my first 1911A1 back in December.

However, this is still my favorite .45!

When size matters.

Some reach for their 50BMG.

The 9mm is a metrosexual pistol. The .45 is a man's gun.

When I qualified on the .45 in the sixties it was a foregone conclusion that it was the only sidearm that would not only kill someone but knock them down too. Even if you hit them in the finger.

Hoping to add a Colt 1991A1 to my collection in the near future.

Isn't the Glock 37 in .45GAP?

The military would have to transition to a completely new cartridge that isn't compatible with the 1911s & MK23s already in service.
