Submachine guns are underrated

If I could carry a submachine gun for a sidearm, I wouldn't -- too big and heavy. I'd carry the same guns I choose now.

But I would choose a suppressed M3 submachine gun for my housegun in a heartbeat...if they were not so restricted! I think the "dislike" of submachine guns is an attempt to rationalize not having by pretending we don't need it. A bit like the Soviets pretending there was something better about living in the USSR than in the US...when they had no choice about it.
 
Back in the early or middle 1980s, one of the shooting schools got some folks together who were top-shots with pistols, and quite familiar with sub-guns. They made numerous runs through a Fun House.

Counting hits against time, the pistols always won. Always.

Yeah, full-auto is Great Fun. No doubt. BTDT. It's also a great way to convert money into noise.

Get a rebvolver or pistol you like. Practice. Practice some more. You'll be able to do all you'll ever need to do, without worrying about how neatsy-poo and kewl you are. :)

Really

Isn't this a moot point, as the common guy here on THR has never even held a full-auto sub-gun, let alone be able to cary one for "everyday use"?

If I could tote something with "da switch" it would be an AK...why? Reliable, fairly accurate for intermediate use and a relatively small package with a good punch to say 250-300 meters...not to mention the 75 round drums,etc or if I had to an M4...but only if I had to
 
An M4A1 with a Noveski 10" upper is just as compact as your MP5 with all the terminal effects of 5.56x45 out to about 100 meters.

LOL I don't know if thats a typo or not but with a 10 inch upper even the very best of ammunition will only get you around half that... Maybe 2/3rds...

Then you're talking about a big ol fireball and very loud explosion compared to an SMG I think.

In addition its been proven that the 5.56 really doesn't have a reduced chance of hurting someone a few walls away. You're taking your chances when firing any gun in a house.

In any case I think the SMG is on its way out, although sub 14 inch 5.56 carbines probably won't become all that popular either.

I do believe that machine pistol/PDW weapons will become very popular as time goes on. The world is only getting smaller and more confined, and the terrorists know now that they can't hide in the open, they have to hide in cities. Also as terrorist attacks become more frequent, concealable arms such as the MP5K and the various PDWs and MAC type weapons will be necessary to fend them off.

Look at the weapons that bodyguards guarding VIPs carry in countries that aren't a warzone: hidden machine pistols and pistols. Only in the most dangerous of warzones do they carry rifles, because there nobody cares if your bodyguards have M4s.

The optimum effective range for 77gr Mk262 or equivalent is around 100 yards from a 10". With 6.8SPC (10"), it'll be further.

No typo, no one said you were limited to military ammunition. If you a limited to military ammunition you can get acceptable terminal effects from MK 262.

You obviously have no experience with the Noveske Rifle Works KFH and KX3 flash suppressors. They make 10" barrels usable. http://www.jnrifleworks.com/cgi-bin/cart2/display.cgi?cat1=17

No one ever said that there was no danger from shooting 5.56 in a house. It is better then pistol ammunition for both terminal effects and less chance of collateral damage a few walls away. that doesn't mean it can't kill after going through a few walls, it just means that the fragments have less of a chance of killing or creating serious injuries. There are no indoor safe bullets that are effective.

In any case I think the SMG is on its way out, although sub 14 inch 5.56 carbines probably won't become all that popular either.

Actually they are becoming very popular. The need for shorter but yet effective weapons for use from vehicles and in buildings has brought the 10" barrels out in quantity.

I do believe that machine pistol/PDW weapons will become very popular as time goes on.

PDWs are a solution looking for a problem. They aren't as compact and portable as a pistol, and they aren't as effective as a rifle. They do have a rather high CDI factor, but then CDI doesn't win many fights. :uhoh:

The world is only getting smaller and more confined, and the terrorists know now that they can't hide in the open, they have to hide in cities. Also as terrorist attacks become more frequent, concealable arms such as the MP5K and the various PDWs and MAC type weapons will be necessary to fend them off.

MP5Ks and MAC-10s and 11s were never anything more then novelties. Fun toys for gunners to play with but they were never serious fighting weapons.

Look at the weapons that bodyguards guarding VIPs carry in countries that aren't a warzone: hidden machine pistols and pistols. Only in the most dangerous of warzones do they carry rifles, because there nobody cares if your bodyguards have M4s.

VIP protective details is one of the few roles left for a submachine gun. But they are being phased out in favor of the short 5.56 mm weapons. 10" barreled M4s, even short G36s.

The submachine gun was born in the trenches of WWI. It reached it's maximum utility in about 1943. By 1944 the MP-44 was being fielded in some quantity. The submachine gun's days as a viable military weapon ended with the MP-44 and the advent of the assault rifle. It received a revival of sorts in the police special operations community, but by the 1990s both military and police special operations units had begun phasing them out for short assault rifles.

In another 5-10 years the pistol caliber submachine gun will be a footnote in the history of small arms development, having gone the way of the flintlock and percussion muzzle loaders.....

I have a real MP-5 and I wouldn't want to be on the receiving end of it.It has never jammed ,always reliable,accurate,collapsable stock.the only other thing I could want is a 100 rd mag for it.

Guess you're one of the few who understands when a subgun could make real sense.

For home defense, the shotgun is best. You can aim over the barrel without needing to see sights, which makes hitting in low light much easier. Don't tell me about lights, laser, aimpoint, .... I'm talking home defence, not SWAT.

If you shoot a .223 in your living room you're flashbanging yourself. Especially with a short barrel. That's what rwong with the MP7 BTW, it has a very nasty report.

And somebody asked what KSK (Kommando Spezialkräfte) is, that's German army special forces

Been watching El Dorado on DVD again? :rolleyes: You have to aim shotguns unless the hit you need to make is written into the script. Any idea of how big a pattern is at room distance? Not much bigger then the bore. A shotgun is not a point and click interface. :uhoh:

Don't tell me about lights, laser, aimpoint, .... I'm talking home defence, not SWAT.

So are you telling me that you're going to shoot at a shadowy figure in the dark? Without a light, how will you ID the target as a threat? It would be a heck of a thing to live with shooting a family member who had come home unexpectedly.

If you shoot a .223 in your living room you're flashbanging yourself. Especially with a short barrel.

What's your personal experience with this? You've never used a 10" barrel with the Noveski flashider before if you believe that. Try shooting your 12 gauge indoors and see what kind of flash bang effect you get.

And somebody asked what KSK (Kommando Spezialkräfte) is, that's German army special forces

I asked, thanks, it was an acronym I hadn't seen before.

See!

Told yall they're underrated.

OK - I was assuming that a MP5 cost as much as it should be - about 850-900 $. And I was (sorry I didn't mention it) assuming the '68, '34, and '86 bannies weren't enacted. ¡Perdon ese!

We all know that SMGs are much more easily suppressed than an assualt rifle, right kids? No use for your little M4 with the big crowd-impressor flash and bang. Not very good, eh?

And I missed another thing: How many magazines of SMG ammo can you carry for one standard assualt rifle magazine? My guess is 3. So you can 30 rounds of, let's say, .308. Well, let's throw the swing your way a little; 5.56x45. While you carry 30 of those, I can carry 90 of mine. :neener:

What about that shotgun? Oh yeah, those. What kind of weapon would you like to carry in a, say, rather tight factory. An assualt rifle? Humm, might be a little tight for that. A pistol? Well, nice for the closer zombies. (oops :what: ) A shotgun...Similar, but not quite. How are you going to shoot across the factory from a good position accurately with a shottie?

Remember, the Army did some homework and found most engagments were under 200 yards. Right? When you're running around, how are you going to see a 1 MOA figure across the field anyway?

Let's not dismiss that you can still carry more SMG ammo than a shotgun. We assume that you don't fire full auto all the time. SMG maggies are smaller and lighter, so you can carry more of them than an assualt rifle. Besides, what difference is a rifle going to make in a half-gutted, half-collapsed building? You might have to carry your rifle hip style, but the SMG might be small enough to work your shoulder a little.:eek:

That's why most military units and police departments who previously used submachine guns have abandoned them in favor of 5.56mm carbines. They just didn't have you to advise them before they made the switch. They made their decison based on actual combat experience..everyone knows that doesn't mean mush when it interferes with an American gunowner's preconcieved notion of what works. :banghead:

We all know that SMGs are much more easily suppressed than an assualt rifle, right kids?

Pistols (and submachine guns, because by definition they shoot pistol ammunition) are easier to suppress because of the smaller volume of gas and because many pistol rounds are subsonic. Once again, you give up terminal effects for quieter operation. Isn't the object of shooting someone to incapacitate them as quickly as possible? Aren't you making a trade off when you suppress an already somewhat ineffective round? Rifles have much better terminal effects then pistols...That is a fact.

No use for your little M4 with the big crowd-impressor flash and bang. Not very good, eh?

Have you ever fired an M4? Or is all your your experience with this type of weapon's signature the Hollywood variety with the kewl looking muzzle flash separated by the tines of the flash suppressor? The standard issue birdcage type flash suppressor is quite effective, the aftermarket Phantom is better and the Smith Enterprises Vortex the best. None of these will make a 10" barrel comfortable to shoot though, because of the blast of gas. Enter the Noveske flashiders:
http://www.jnrifleworks.com/cgi-bin/cart2/display.cgi?cat1=17
The idea was taken from the Krinkov type flashiders that were developed for the short AKs (yes, even the Soviets, who fielded more submachine guns then any other army, moved to a short barrel assault rifle). These devices do work. I have fired an M4 equipped with one and had a couple on the line with me at Pat Rogers carbine course last July.

While suppressing a rifle is harder then suppressing a pistol or submachine gun,it's far from impossible. SureFire and Gemtech both make excellent suppressors for 5.56mm weapons.
http://www.surefiresuppressors.com/
http://www.gem-tech.com/m4-96d.html

They not only work very well, but they are in use now. Now we have a package as compact as an MP5SD3 with the much superior terminal effects of 5.56x45 in a package that is more ergonomic then the MP5 but just as comfortable to shoot.

And I missed another thing: How many magazines of SMG ammo can you carry for one standard assualt rifle magazine? My guess is 3. So you can 30 rounds of, let's say, .308. Well, let's throw the swing your way a little; 5.56x45. While you carry 30 of those, I can carry 90 of mine.

You're telling me that you can carry 90 magazines of 9mm or .45? :what: Man how much do you bench? :uhoh:

Have you checked the scale lately? Both 9mm and .45 ammunition weigh more per round then 5.56mm. Most submachine guns use a steel magazine where the M4, G36 etc. all use aluminum or plastic. Round per round 5.56mm weighs less.

Remember, the Army did some homework and found most engagments were under 200 yards. Right? When you're running around, how are you going to see a 1 MOA figure across the field anyway?

Most small arms engagements are 100 meters and under. But what does that have to do with this debate?

SMG maggies are smaller and lighter, so you can carry more of them than an assualt rifle.

See above, pistol caliber ammo and submachine gun magazines are in fact heavier then 5.56 mm ammo and assault rifle magazines. I don't have a postal scale here, but if you want tomorrow I will weigh a loaded Uzi magazine and a loaded USGI M16/M4 magazine and prove it.

Besides, what difference is a rifle going to make in a half-gutted, half-collapsed building? You might have to carry your rifle hip style, but the SMG might be small enough to work your shoulder a little.

You're going to carry whatever weapon you have, be it submachine gun, rifle or shotgun at either low ready or indoor ready. Have you ever done any CQB work, even in training?

The submachine gun was just what was needed in it's day. Most rifles in military or police service were bolt action and the semi-autos, M1, GEWHER 43 etc. were long, heavy and didn't adapt well to being cut down to a handy enough size for close quarters operations. But that day passed. In fact it passed a very long time ago, sometime in late 1943.

Submachineguns are a very cool solution to a very narrow problem: clearing several rooms, or protecting a principal, of an unkown number of actively lethal baddies. The operator should be well trained both in deliberate disciplined use of the SMG, and in keeping cool & comprehensively rational in the given situation. Unfortunately for the cool factor, for most of us this is unlikely in both probability of situation and timely preparation therefor.

There is little that a SMG (let's say the MP5 in particular) can do that an M4 can't. 5.56 rounds are slightly lighter and penetrate body armor where 9mm won't. Length is the same given the same barrel length (18" plus given barrel). M4 is trivially heavier (if at all). MP5 may be collapsed a little shorter - an advantage only if you have enough reason to carry an uncomfortably bulky gun under your jacket.

Shotguns compare favorably as well. The base length of a Mossberg 590 is 20", just 2" more than the MP5 & M4, with subsequent length decided by barrel. Total actual rounds is of course much lower than the MP5 & M4, but each round can deliver, presuming 00 buck, nine simultanious 9mm balls - that exceeds the 30-round magazines of its competitors in just 4 shells ... which BTW fits nicely into a shortie version of length about equal to the others.

Yes, the new MP7 and P90 SMGs pack more soft-armor-piercing rounds into a compact space ... but what they gain in penetration they lose in punch, leaving the only benefit a smaller package ... and then we're back to wondering what your specific application is in the first place.

Mulling it over for a while & comparing statistics, I must conclude:
If you're not a bodyguard trying to cram a lot of AP firepower under your suit coat (and that limiting you to the MP7 or P90), SMGs are not for you. Any other application allows for a slightly larger tool that provides a tremendous increase in firepower.
 
I own a submachine gun.
I am going to buy another one (probably an MP5) in the very near future.
I have fired all manner of submachine guns.

Assuming I was free to use anything I wanted for self defense or military combat, one of the last weapons I would choose would be the submachine gun. I don't even consider it to be practical.

This little story doesn't relate much information because you had to be me to appreciate it, but.................
I was participating in a local subgun match. But, to add a little spice to the course of fire, the match director added a rifle into the mix. You started off with your subgun lying on the table ready to go, you had a rifle in your hands at the low ready. When the buzzer sounded, you used your rifle to knock down five pepper poppers at 50 yards: when they were all down, you laid down the rifle and picked up your subgun to engage a whole bunch of other reactive targets.
When my turn came, I fired off five shots in a couple seconds: five targets down. I almost had to force myself to put the AR15 down to get my subgun. I knew I could easily win with my AR. I could knock the targets down FAR faster on semiauto with the AR than I could on full auto with the subgun: and do it with one shot per target.
This was a big moment for me. I had been in discussions like this before over the years but at that moment it all became crystal clear for me.
Subguns are real fun toys.
If TSHTF I want an AR15 in my hands.
The subguns stay in the safe right next to the shotguns, the HK91, the FAL, and the M1A.

The size and length of the subgun has been cited as an advantage for close quarters:
I have two AR15s registered as SBRs: a 7.5" (I ordered the Noveski flashider for it, but haven't received it yet) and a 10.5". I also have a Vang choked 870 registered as a SBS with a 14" barrel. How about muzzle blast and noise ? I have an AAC M4-2000 suppressor. I can attach this suppressor to a 16" AR15 and it is only an inch or two longer than a 20". Put it on the 10.5 and it is shorter than a 16" AR. The report is similar to a .22LR Rifle.

I recently fired an AK on full auto at an IDPA silhouette. I was not able to hit the target with two rounds per burst from 50 yards. Up real close I could put my first shot COM and one more superficial hit before they started hitting the berm. Now I grant you, I have not trained with the weapon and could probably do better with experience: but, I could have put at least two rounds COM with the gun on semi in the same amount of time.

As someone who has carried both, I can assure you that 30 rounds of 9mm is heavier than 30 rounds of 5.56mm.

I've never been live in a factory but we have done quite a bit of simunitions training in one. A pistol and an AR work just fine. My issued 870 has a 14" barrel, maybe 34" overall. The AR has an 11.5" barrel and is about 27" with the stock collapsed.

How often are you planning on clearing a factory? And what sort of "personal defense" efforts are you expecting in this factory?

They aren't popular because they shoot pistol ammunition. If you are going to carry a rifle size package, you might as well shoot a real rifle.


My thoughts exactly.
 
Yep, a great choice as long as you're not concerned about how long it takes to incapacitate your enemy after you shoot him. I'd pick short and maneuverable over terminal effects any day of the week....NOT!

Well, so far in the REAL world the 5.7x28 has performed well, all the BG-s who ate those (average 1-3) never made it. 5.7x28 military round has plenty of stopping power at the distances it was ment for. It's not a rifle round indeed but it fills it's purpose very nicely. I undestand your affection in american equipment but face it, people outside can build effective arms too.

1 round of 5.7x28 (SS190) weights 98 grains, 1 round of 5.56x45 (SS109) weights 182 grains. Which one is lighter?

Let's see some proof, offical after action reviews and autopsy reports. SS190 didn't exactly receive glowing reveiws from any other recognized agency or expert that tested it.

The Royal Canadian Mounted Police forensic laboratory had this to say about the SS190:

Abstract:
PURPOSE: To establish the wound profile of the 5.7x28 mm FN cartridge (SS190) fired from the FN P90 submachine gun.

Method: 10% ordnance gelatin, gelatin covered with heavy clothing, and gelatin covered with Barrday Inc. Level II soft body armor was shot at 3 m and 25 m with the FN 5.7x28 mm SS190 cartridge fired from the FN P90 submachine gun.

Results: The average depth of penetration in all test events was 10.4 inches with no bullet deformation and fissures created by temporary cavitation not greater then 3 3/4 inches.

Conclusion: The 5.7x28 mm SS 190 FN cartridge fired from theFN P90 submachine gun lacks sufficient penetration and has a limited wounding potential as a handgun ammunition unless penetration of soft body armour is necessary.

You can read the entire report in the Spring 2000 issue of Wound Ballistics Review.

In an article entitled Personal Defense Weapons an Answer in Search of a Question, published in the Spring 2001 issue of Wound Ballistics Review, Charles M Hayes gives us a chart comparing various cartridges:

Comparitive Penetration in Unprotected Gelatin at 50 Meters

Cartridge Penetration
5.7x28 ------ 23 cm
4.6x30 ------ 28 cm
.224 BOZ ------ n/a
5.56x45 SS109 ------ 34 cm
5.56x45 M193 ------ 36 cm

Note: Both 5.56x45 mm rounds fragment at velocities above 760 m/s causing large permanent wound cavities. (see text)


So it's time for you to put your money where your keyboard is. You stated that the 5.7x28 round is doing well in the real world. The ballistics community has seen this round for what it is since 1990 or earlier. Obviously my nearly 29 years as an Infantryman in the US Army and my experience as a police officer on a tactical unit since retirement isn't as real as yours. So let's have the details.

The gauntlet is thrown down...pick it up and prove me wrong with facts about the real world performance. News reports and anecdotal evidence doesn't count. I can present science, you show me your science and prove mine wrong.

My half cracked opinion

There's a tool for every job. Shotties, rifles, handguns. With a submachinegun you put the power of a pistol in the size of a carbine rifle. Big deal. Do the reverse, rifle power in a pistol sized platform, repeating and manageable, then you've got my attention. Until then, I'll use a pistol when I want to touch off a pistol round. Oh, I have used subguns before. As you can tell, I was underwhelmed.
 
The Subgun's useful life is well over in Law Enforcement. With the advent of reliable compact carbines, and accurate, compact shotguns, the void has narrowed to nothing, leaving no room for the pistol caliber gun.

I would take a good 12gauge any day of the week over a 9mm or .45acp subgun. Just no compariosn. The Shotgun is far more versatile, and has nearly equal ACCURATE effective range. If you dont believe that, the you need a good shptgun, and some serious shoulder time. I am confident in my 870 at more than 150 yds with good slugs.
 
Jeff, great posts, and good info.

Let me start by giving my own credentials in this debate. I first trained (South African military) with submachineguns in 1976, and had ongoing training with these and other military weapons (from all corners of the globe) until 1991. From that date, my training has been private, rather than military, but I've kept current with developments.

Let's now take a look at a little history. Prior to WW2, the military rifle options available all employed high-powered cartridges. There was a strong bias in favor of rounds that could be effective over several hundred (up to a thousand) yards. This was one reason (the other, and primary, reason being the availability of millions of rounds of .30-'06 ammo) that lay behind General MacArthur's decision to veto the Garand rifle in its original .276 caliber, and insist that it be chambered for .30-'06.

When a lighter, handier weapon was found to be desirable, initially during trench warfare in WW1, and later for close combat (particularly in urban areas) during WW2, the obvious solution (in the absence of any intermediate-power rifle cartridges) was to chamber handgun cartridges in a full-auto weapon. The Thompson, Schmeisser, etc. were all produced in response to this perceived need. They did fairly well in their time.

During WW2, intermediate-power cartridges were introduced for the first time, notably the German 7.92mm. Kurz, the US M1 Carbine round, etc. These offered performance and ballistics greatly superior to pistol cartridges, and not all that inferior to full-patch rifle rounds at close ranges. They led, in turn, to development of first the 7.62x39 by the Soviet Union, and later to the West's adoption of the 5.56x45mm. These rounds meant that the recoil (and bulk) of "traditional" service rifles was greatly reduced. It didn't take long for smaller variants of these weapons to be introduced, and these, in turn, dethroned the sub-machinegun in short order, offering vastly superior ballistics and power in a compact, easily-handled platform.

The sub-machinegun is now very, very limited in applications, as the short-barreled, compact assault rifle in an intermediate cartridge offers so many advantages over it. I was trained to rely on the SMG for very-close-range encounters (shipboard assault, house-clearing, etc.), and to use ammo to "sweep" an area, rather than target a specific individual. When individual targets were encountered, we were trained to fire short, controlled bursts, and cautioned that our ammo would probably not produce immediate incapacitation due to its low power. Combat experience was cited to prove this. As soon as more powerful assault weapons were available, our experienced troops "lost" their SMG's and went to the better weapons. It was common for captured AK-47's (particularly paratroop models) to be adopted wholesale, as they were far more effective in the SMG applications than the Uzi's, MP-5's, etc. then issued.

I don't know of any military outfit that today relies on SMG's as primary issue weapons. Some police and security outfits still do so, but those that have been able to afford it have almost universally moved over to short-barrel versions of assault rifles, chambered in any of the standard military calibers of today. SMG's are headed for the barn, having seen their day.

The whole PDW market is in a state of flux. Don't forget that much of it has been driven by European ideas of weapons development - the same Europe that until recently issued .25 ACP and .32 ACP pistols to its police forces as being "effective" calibers. No US police force would accept these guns, even for backup weapons! The FN P90, for example, has sold moderately well in Europe and elsewhere, but largely to forces unable to use short-barreled assault weapons. Where the latter are available (and legal), they're almost universally preferred over the PDW paradigm.
