Thompson SMG in 30 Carbine

/ forgottenweapons
Cool Forgotten Weapons Merch! shop.bbtv.com/c...
When the US military released a request for what would become the M1 Carbine in 1940, the Auto-Ordnance Corporation offered up a Thompson submachine gun simply rechambered for the new .30 Carbine cartridge. This entailed a new magazine, a receiver modified for the longer magazine, and a new barrel and bolt face - but the other Thompson parts could remain unchanged form the standard .45 ACP models. This made the submission a pretty cheap and easy effort for Auto-Ordnance...which is a good thing, considering that it was almost assured to be rejected.
The stipulations for the new carbine included a weigh requirement of 5 pounds, and the Thompson weighed more than double that (in both .45ACP and .30 Carbine forms). Only a few were made, and the one submitted for military testing was rejected outright on the basis of weight. This example is serial number 1, and resides at the Cody Firearms Museum.

Fun Fact: this weapon appears in the first level of Wolfenstein the New order as the "SMG" . In the Canon it replaced the M1 and Sten in allied arsenals despite it's high cost as it was the only weapon capable of breaching the gap against the German Assault rifle, and as troops became extremely precious to the US and Britain after the Failed invasion of France resulted in the Extermination of the First and second US Armies and the Nazi counter invasions of Ireland and Canada.

[@agentjohnson3973]

Wow i never knew that! Thats awesome, thanks for the info.

[@Blazcowitz1943]

I never heard anything about that, but in my headcannon the Thompson used in the New Order was the "Thompson M1946".

[@OccamsToyota2]

It would've made more sense if they'd just issued the more affordable M2 Carbine..

[@HellbirdIV]

@@OccamsToyota2 Maybe not. You have to consider a few factors: First, that the Thompson was still in mainline use by US and British troops, it's the weapon they were familiar with, and in widespread production and with spare parts. Consistency is not unimportant. Secondly; The Thompson is heavier than the M2. This isn't always a bad thing. The M1 and M2 are not meant as frontline assault rifles, they are meant as essentially upgraded sidearms for truck drivers, squad leaders, mortarmen and anybody else who doesn't have a rifle as their primary weapon. The .30 Carbine Thompson gives you a more durable design which can serve longer as an actual frontline weapon in more harsh combat conditions, which is a better choice for arming fewer but more troops than the cheaper but flimsier M2 which would be better for mass-issue to rear-echelons and support personnel. Personally, if I were designing the world I would've given the Allied troops a whole new "Assault Rifle" because the US would've certainly had the industrial capability to rapidly develop and adopt one, probably a scaled-up M1 Carbine, chambered in a cut-down .30-06 similar to the 8mm Kurz. I'm imagining a fictionalized Ruger Mini-30 chambered in .300 Blackout, in terms of its overall appearance and dimensions.

[@coreytrevorson606]

@@HellbirdIV I question the idea that the .30 carbine Thompson would be more durable than the M2 carbine--it was effectively just blowback operated, while the M2 actually had a locked breech, meaning that its action would be subjected to greater wear than that of the M2. Also, in war, a lot of materiel just ends up getting destroyed or captured anyway, so reducing that loss is another reason to go with the cheaper gun. There are reasons why the Thompson was fairly quickly phased out and this version never even went anywhere, after all. Also, In real life, the M1 carbine ended up in front-line use during WWII and the M2 had largely replaced the Thompson by the time of the Korean War, despite the fact that this wasn't the original intent of the M1 carbine, because it and the M2 were still sufficiently tough while being cheaper. Then again, in the Wolfenstein canon, the Allies lost, so, in that context, it makes sense for them to have made the mistake of using this version of the Thompson and not the M2 carbine.

[@bryangrote8781]

Interesting. Since .30 Carbine is a light rifle round, effectively an “intermediate cartridge”, and the Thompson is capable of semi or full auto fire, Auto Ordnance basically created an assault rifle without intending to. Not a very good one since it’s a bit low powered, too heavy, and a bit short in barrel length, but still fits.

[@-John-Doe-]

It’s an intermediate cartridge. Anyone who says pistol round is just repeating fudd lore. It’s a replacement for the 1911 just like a Glock is a replacement for pepper spray. That doesn’t mean a Glock = pepper spray. _____________ 110 grain .30 caliber round @ 2000 fps = pistol round But 110 grain .30 caliber round @ 2200 fps = .300 blackout the best cartridge ever developed. It’s 98% of the muzzle energy of 5.45x39, but it’s a pistol round. Got it. _____________ They traded 200 fps and about 20 yards of point blank range, for an assault rifle that weighed 5 lbs instead of 10. Not much of a trade off when you’re surrounded by semi auto 30-06 rifles. The US never adopted a cartridge like the 7.62x39 for a reason. The same reason the soviets abandoned it. They replaced the carbine round with 5.56.

[@darrengarcia4937]

@@-John-Doe- except the .300 BLK makes alot of sense considering its BC is also better and has heavier grain bullets.

[@-John-Doe-]

@@darrengarcia4937 It makes a lot of sense over half a century later after the light rifle project developed into the AR15 with modern materials - Aluminum, Polymer - and a very high pressure cartridge. It works if you already designed the AR15 and 5.56... but it’s not going to replace the 5.56 for a reason - the same reason intermediates weren’t adopted - the same reason the .30 carbine wasn’t compromised to be something it’s never intended to be, or .300 blk will ever be. You have to know precisely what the design parameters are for the firearm. Shortening the OAL of the cartridge is necessary for lightening the firearm and ammunition, and for logistics purposes. This is the entire purpose of the T65/ eventually 7.62 NATO replicating .30-06 M2 Ball in a short action. Smaller firearm, smaller magazines, etc. You _could_ sacrifice the design for a slightly higher BC and 20-25 extra yards of point blank range... but the United States military wasn’t interested in that at all. Just like the US military was never really interested in submachineguns - the Thompson was pressed into service and the M3 grease gun was designed to fit the niche as cheaply as possible.

[@darrengarcia4937]

@@-John-Doe- there is a big issue with your argument. The reason intermediates werent adopted was because of the stupidity of the US Aquisitions. We decided on the 7.62 NATO round contrary to better performance out of the .280 and .270 british. You cant paint the US as a all-knowing and correct benchmark when they have a history of making stupid decisions. I.E. the M14, 7.62 NATO, Incorrect ammo types and cleaning kits for the M16, the terrible mods done to the M16A2, the M249 mag adapter.

[@darrengarcia4937]

@UCCoTBHMhI4wxaPknjDHh07Q because it was better in literally every way. Only reason the Russians cant is the fact that they are so poor. A stockpile of inferior 7.62x54 weapons and ammo from the USSR days keeps their army as a army. Its hard to change your vintage with a GDP like that. We could have done it in the 50s but we had stupid people in charge that stuck with the 7.62 NATO and M14 instead of the FAL or EM2 in .280 even though both rifles and calibers were better in testing than the .308 which the US tried to hide the evidence of. Only took a bunch of dead troops to realize how big of a pos the M14 was and to field the M16 even though they even tried to sabotage the 5.56 and M16.

[@tillmannfischer]

+Robbie Dickson The Soviets never even thought of the concept of an assault rifle, though. In Soviet infantry doctrine, there were submachine-guns and rifles, nothing in between. And there's more to it than just a fancy name, the Soviets simply employed those weapons as rifles (and the AKs as SMGs). This also reflects in Soviet marksmanship training, the AK-47 was expected to be used at far lower ranges than the cartridge and the weapon actually permit, everything beyond that was meant to be engaged by "sharpshooters" (in US terms that specific role would be a marksman).

[@tranq45]

Auto-Ordnance missed a number of easy bets when they didn't pursue lighter and more compact versions of thier SMG. A stamped-metal SMG using a wire stock would've likely met the weight, and would likely have greatly reduced cost.

[@AndrewSmith-cn3nw]

The military didn't even test fire it? They could have at least done THAT. Sure, it didn't fit the bill for a carbine, but if the military was going to keep using the Thompsons it had, it would be interesting to see the merit of having one chambered in .30 Carbine versus .45 ACP. They might have found some use for it somewhere down the line.

[@charlesinglin]

I've thought the same thing. If it worked reliably there would have been a logic to switching to a .30 SMG and phasing out the .45 Thompsons. It would simplify the ammunition supply, since they'd only need small amounts of .45 for pistols, and the .30 Carbine rounds are quite bit lighter than the .45. I imagine they were scrambling to produce enough weapons at the time they didn't want to interrupt the production lines.

[@AndrewSmith-cn3nw]

Charles Inglin​ But would it kill as well as a 45? At short range with a center mass shot, probably not. It just seems almost insulting that nobody in the military even test fired it after Auto Ordinance went to the trouble of designing and building a prototype.

[@hornmonk3zit]

.30 Carbine virtually identical to .357 magnum other than the diameter, so yes, it would kill a Nazi just fine. Especially if it were full auto.

[@samhouston1288]

Is it going to be controllable though? By itself, a .30 carbine is not hard to handle, but what about when being fired at 700 rpm?

[@hornmonk3zit]

.30 Carbine and .45 ACP aren't all that different in recoil. .30 is probably going to be a touch snappier, but it's a 12 pound gun, it'll be fine.

Seriously, a 30 carbine submachine gun with a huge magazine capacity could have been pretty effective. At double the velocity of the 45 acp it and even less recoil, it might have been better than the 45 acp...

[@MrMorganQuinn]

Except you would be complete ignoring the contemporary American military doctrine with it's emphasis on individual accuracy as opposed to Soviet dedication to massed fire, which you see later in the development of the Armalite vs. Kalashnikov rifles.

[@abitnutz6747]

So you're saying that the thompson in 45 acp meets that doctrine and a Thompson in 30 carbine wouldn't?

[@RGA1944]

The Thompson was adopted because US military early in WW2 suddenly felt the need of a SMG without having a purposedly designed gun. Had they had the same vision as the Russians, they would probably have mass-produced the Reising SMG: equally effective but lighter and much cheaper.

[@abitnutz6747]

I have no argument with any of that. All I'm saying is that a Thompson in 30 carbine, with almost no recoil, a very high capacity magazine and twice the velocity of the 45 acp, may have been more effective than one in 45 acp, especially at medium ranges.

Something about this gun just gets me everytime. I own both the Thompson M1A1, and the Thompson M1928 Chicago Typewriter AEG's, as well, both from Cybergun/CYMA/Thompson, Auto Ordinance out of Worcester, MA.

[@USAAmutual45]

I honestly believe a M2 is a exceptional "SMG", at least in experienced shooters hands, recoil can be a bit much for most shooters. For some reason I thought this would be in that class, completely forgot about the whole weighing 5kg, thats a deal breaker. Although it would have been more accurate and longer ranged then the 45.

Interesting idea. The only other 30 Carbine SMG i have ever heard of is a Dominican Republic one from i think the early 60's. It's mentioned in Military Small Arms of the 20th Century.

Hello Ian, Forgotton Weapons has become one of my favorites on KZbin. Does the current Auto-Ordnance / Thompson producer produce a semi-automatic version of the Thompson for the .30 Carbine cartridge? If not, this might be interesting, you think?

[@darnit1944]

Sadly, no. This is the only prototype in existence. They rejected the carbine due to high manufacturing cost. The US at that time is not in war yet, but they're slowly entering.

[@VintageTrollean]

This is the second time a video has been released at approximately the same time as an Ahoy video about that gun.

[@Jurflip2]

Another note: The recoil impulse of the .45 ACP cartridge, at 940 ft/sec, which is approximately what it did from a Thompson's 10 inch barrel, is about 43 J/s (43 kg.m/s). The 30 carbine would have done about 1800 ft/sec from a 10 inch barrel, I expect. That would have resulted in a recoil impulse of around 46 J/s. It should therefore have been quite possible to fire the 30 carbine round from the Thompson, using the standard Thompson bolt, adapted to the 45 ACP cartridge base. The rate of fire would have been somewhat higher than the already high rate of the standard gun and the muzzle blast and noise would have been spectacular!

[@wcharliewilson7004]

Ian, how about doing a piece on that FBI Thompson conversion to 10mm?

[@thatpersonpeopledontlike7549]

why does it seem the US military missed so many great opportunities for updated weapons

[@friendguy13]

Because the army keeps asking companies for better small arms but never wants to pay for them...

[@riverstyxarmory9782]

the receiver is even cut for drums. very optimistic for not being adopted.

[@zuseram7729]

can they let you shoot some of the guns. I wood love to see that. nice video and keep it up bro. much love

[@ForgottenWeapons]

As a formally accredited museum, they cannot shoot items in the collection.

[@thewiezman]

Forgotten Weapons who made that rule? That sucks :(

[@ThompsonExpress]

In an Alt History world. "This Thompson Submachine gun was used in the famously failed assault in the Deathhead Keep in 1946..."

[@Psiberzerker]

God i want one of these. I always wanted one. Actually, can I get that in .357 S&W Magnum?

[@drmaudio]

I suspect that would actually be a very usable, controllable carbine. I wouldn't, however, want to carry it for long.

[@Ross665]

Rather interesting, odd weapon. Makes sense, but if I had been told before seeing this video that a .30 Thompson existed, I would have thought it was a conversion done as a one off by a individual.

[@Treblaine]

As a "light" rifle it was a failure, but someone could have said "wait, why don't we just adopt this as our submachine gun? Instead of this same gun in .45ACP?"

[@Crayfish]

Car-bean and car-byne are interchangable.

[@PaperHunter]

Bendik Eidshaug It's a fine line between Carmine and carbine :)

[@Crayfish]

I dont see any fine line. Maybe you are mistaking it for a "b"?

[@TheCoffeehound]

+Bendik Eidshaug He was making a joke and a rhyme.

[@LeminskiTankscor]

Wonder what the handling and performance would have been like vs a .45ACP 1928 Thompson...

[@ch0k1ngh4z4rd]

I wonder what the rate of fire is/would have been. I've read that some M3 grease guns chambered for .30 carbine were developed for testing, but never adopted, partly due to the absolutely ridiculous change in cyclic rate.

[@MagraveOfGA]

I wonder how hard it would be to convert a modern semi Thompson to .30 carbine...

[@edwhatshisname3562]

I'd be willing to bet that thing would have a lot of climb to it in full auto.

[@edwhatshisname3562]

@Craig Scott What makes you say that?

[@edwhatshisname3562]

@Craig Scott I hadn't considered the weight, that's true it probably would be more manageable than a full auto carbine.

[@micnor14]

It was a twenty rounder. You can look at it and tell it's about 10 down and side-by-side.

[@JamesThomas-gg6il]

I think that since AO / kahr is making the semi auto carbines, maybe they should bring this back. Id buy one.

[@zuestoots5176]

the Thompson and the Grease Gun are the Modular engines of the gun world. 3 great engines, all tooled with the same steps.

[@DoughboyJonesmk2]

What did they do, use the exact same barrel and just bore it to .30 caliber? That would explain at least some of the weight gain...

[@koosh138]

Is it possible to have a custom built Thompson with the 30 mag rounds? At least then somebody would say the fun of shooting it.

[@burnoutteamclubbtcp7283]

the gun made an appearance in the vr game, hot dogs horseshoes and hand grenades where it fires from an open bolt and is fully automatic

[@ichimonjiguy]

I'm wondering if it is closed-bolt or open-bolt; and what locking mechanism is used. I like the idea of .30 carbine SMG.

[@ArmamentAxes]

huh never knew there was a 30 carbine Thompson.

[@ccfmfg]

They should have chambered this Thompson for the MP44 7.92x33mm Cartridge.

[@KaDaJxClonE]

YES! Thompson in .30 carbine sounds awesome! Way more power than 45acp!

[@thenorthstarsamurai]

This used to be my favorite gun in WW2 shooters

[@mattdickson2]

had they made it lighter and cheaper they could have stopped the adoption of the grease gun

[@Camino377]

Yeah, something as simple as a wire stock or removed altogether could have saved a fair bit of weight.

[@Reactordrone]

The wood doesn't weigh that much, it's the massive chunk of steel that the receiver is made out of that gives them all that weight.

[@cougarhunter33]

Given that the bulk of the weight was from that giant milled steel receiver, it likely would have to have been constructed out of sheet metal like the M-3 just to come close to meeting the weight requirement. Even the M-3 was too heavy by specs.

[@tillmannfischer]

+Matt Dickson You can't make this weapon much lighter, due to the operating design. If you make receiver (which is responsible for a significant chunk of the weapon's weight) any lighter, the weapon stops working.

[@Riceball01]

The M3 is surprisingly heavy for what it is, seeing pictures of them I always thought that they were fairly light, then I got to fire one once and I was surprised at how heavy it actually was. On the plus side, the recoil was surprisingly mild for something that fires .45 ACP and considering the reputation the Thompson had for harsh recoil.

[@worldtravel101]

Awesome! i had a great time in Cody!

[@Feiora]

if they had used polymer for grips and stock, and shaved off some metal here and there, it'd have been an interesting monster ^.^

[@rawblinkproductions5301]

I'm willing to bet that it's heavy weight has got to make the recoil very light. It's basically an assault rifle. I bet the Army would have put them to good use.
