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.

I have a .40 cal. Firestar. It is very compact but really heavy. When loaded it feels like it is a chunk of lead.Pistol recoil doesn't bother me right up to a .44 mag but that is as much as I want to experience. If I had a 50 S&W, I would download for it.

It's got a very sharp recoil, but my biggest problem is that the read edge of the safety bests on my thumb knuckle, and it gets really sore after just a few rounds.

There is no difference in handling and no practical difference in accuracy between ball and SWC ammo. The only thing you get with semi wadcutters is cleaner hole in paper targets for easy scoring.

Full wadcutters with a large meplat have a greater wounding effect in soft tissue than ball, but generally won't feed in autos.

Yeah, but nobody this side of Chuck Norris has the wrists for that. And come on... .50 cal? What are you trying to put down, an 18-wheeler?

My gun is huge, but my firearm is 9mm.

A few weeks back, a friend let me shoot his .50 S&W Magnum revolver. The brass case was big enough to swallow a .45 round whole. With porting, the recoil was managable (then again, we're both pretty big guys)

And as to "what am I trying to put down", if you have to ask, the answer won't mean anything to you.

It's big, it's load, and it makes big holes. What more does a man need?

During the Southeast Asia War Games I popped a VC at about 125 yards with an M-16A1 FMJ 56 grain(I think)three times, he kept coming and coming and coming shooting his AK. It was clear he wanted to get a gringo that day. Well, I was clip deficient and everybody else was busy. So I drew my 45, thumbed the hammer and popped him high in the chest at about 10 yards, it knocked him flat on his back and stopped him cold. When the smoke cleared we examined him and found that I had tagged him three times in the lower torso with the M-16 and ALL three had gone through and out. It should be noted that the 45's were not regulation (my Uncle's special brew of hot round and hollow point, And for the people that are going to write and say that a HP will not work in a 45 - all's I can say is I am here now.)

The next day I made two changes. Since the group I was with had some latitude in weapons choice I switched to MAC-10 in 45 and I ALWAYS kept my 45 cocked and locked.

A guy I knew in my younger days was in WW2. He said he shot a german soldier in the face at close range. The guy didn't have a head any more

There's also the .50 Desert Eagle

I've got access to several Desert Eagles - one of which is in .50.

It sucks to shoot. It feels like someone punching you in the hand with every round. Usually after about two magazines, I'm done.

While I truly love and carry a slab sides daily, I have had occasion to use a 357 with a medium load and reversed wad cutters. Let's just say that that is a wound equal to a Civil War musket and leaves a lot of work for the Corner.

Yes, to the .45. It will put them down and it works well with hollow points if you know what you are doing. I just never trusted the 5.56 round and hated it when I had to trade in my M-14(which I carried for some time.)For close combat give me a shot gun or a .45 cal submachine gun and a 1911, they didn't call the Thompson a broom trench for nothing! I got out soon after I traded the M-14 for the M-16 but still have an affection for large slow moving rounds and large fast moving rounds!

Elmer Keith was my source for many years until he died. He thought the 30-06 was a varmit round!:) However, some of his ideas were correct, large rounds put things down better than small calibers do.

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.

That's a *HUGE* issue. There's a reason that damn near every law enforcement agency in the country went to 9mm back in the 80s. With hollow points, you get decent "stopping power" and can carry a sh!tload of ammo (see my tagline.)

With hollow points, 9mm Luger does just fine. The problem is that the military uses ball ammo, and as the author rightly states, 9mm ball tends to overpenetrate.

If you are restricted to using ball ammo (which the military is, essentially), then it's a no-brainer: bigger is better. If the we ever quit following the BS parts of the Geneva Convention, then 9mm hollowpoint would be just dandy.

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.

Yeah, but our troops rarely get to do that. Usually, their enemy is a 2 metre, 80 kg man.

You are correct, however, I would still prefer 185 grn hollow points in the .45 to any 9 mm ammo. I know, I know, you can carry more 9s and with hollow points they do work fine(this was one of the reasons the old .38 long colt and todays .38 special didn't perform as well as they could, hard lead bullets are just about as bad as FMJ). My personal defense gun now is a .44 special(loaded up a little!)and I love it for it's accuracy and its stopping power, large is better as far as I am concerned but still some people prefer the 9 and if the right ammo is used it is a good defense gun.

Actually, I have a bunch of personal defense guns but carry the .44 most of the time!

The 180 grain hollow point is the flying ashtray. Big fat hole in the middle. I have a couple boxes of the +p 180 grain ashtrays down stairs. More than 500 ft lbs, pretty accurate and I've never had a jam with the stuff. The only problem is the colt bites the web of my thumb with the +p stuff.
