[@juhai7048]

I did my conscript service in the Finnish Defence Forces in 1999 and I received basic handling and shooting training for this gun. So even if it wasn't officially in the inventory anymore, they still trained for it. At the same time, we were trained to shoot the "Military Rifle" as it's called, the Finnish version of the M/91 Mosin-Nagant rifle. The gun I disassembled and shot with, had an extremely strong recoil spring, and was in excellent condition. I doubt it was used much or issued to any conscript ever when it was still in the official inventory. Can't remember the serial number anymore, but it was very high, maybe somewhere in the 50000s? I remember the drum it came with, was in comparison very worn, a bad spring and much lower number. I tried to shoot with it, but it had so many malfunctions (the drum that is) that I got to switch mine to a 36-round box at the shooting range. The original select-fire version is actually pretty nice on semi-auto as well. Easy to hit targets at a range you wouldn't imagine possible with a pistol cartridge and with the amount of training we had with it (one afternoon basically). One thing I also remember, is the lack of "awesomeness" it had. And I mean, with the legend that gun has in Finland, shooting it wasn't hard or had any real "bang" to it. So I was a bit let down by it. I was more impressed with the Mosin. But then again, looking back, it was all about the "balls" of the gun back then, not the fact that it was accurate and well made. So I'll just put that to being too young to know any better :D I was 20 and filled with saucy tales of war written by bad authors :D

One brave Finnish soldier called Viljam Pylkäs ambushed and killed a whole 83 man platoon in one battle with his Suomi submachinegun by himself. He had other guy reloading magazines and some soldiers bringed him more ammo and new barrel because original one got too hot during the firefight and it had to be changed. He shot 17 magazines of ammo (680 bullets) during the firefight. He got mannerheim cross and iron cross from german brothers in arms for this hero work Later when war was over Väinö Linna wrote a book called "tuntematon sotilas" (eng. uknown soldier) and this battle is in that book. Also three movies is made based to this book and there it is in the movie. You can find that bad ass scene by searching "Antero Rokka slaughters a russian platoon" here in KZbin

680 round / 83 bodies = 8 round per kill. That is a stupidly good round per kill rate, especially while under fire from a whole platoon. I can see why Russia gave up on Finland. For context, the WW2 average rate was somewhere around 25,000 rounds per kill, and the current average rate is around 300,000 rounds per kill.

I did my 11 months in the finnish army in 1987-88. We got to shoot that (and some other WW2 era finnish guns) during a training day on the range, more than 40 years after the wars ended. I remember it being quite heavy, but the accuracy was spot on at 50 and 100 meters, and the barrell didn't rise too much even during longer bursts (I seem to recall I had the version with the muzzle brake). The round mag was however not much fun to reload in november coldness and with numb fingers. Thanks for a great video, and for taking me back on memory lane :-)

One thing you didn't mention was the rate reducer in the receiver end cap. At 18:48 you can see a spring through the vent holes. This spring holds a disk against the holes on the inside of the cap. When the bolt comes back, air pushes the disk back and goes out the vent holes. When the bolt moves forward, the disk blocks air flow, so the bolt has a vacuum behind it. This slows it just enough to keep the firing rate manageable.

[@jywert]

When I was talking with my grandfather in his late years about the war. He was part of the far-scouts or "kaukopartiomiehet" In one of his stories, the farthest trip had seen the Murmansk railroad. One of my friends had real m/31 but the barrel was decommissioned. We asked if wanted to see it. He said yes. My grandfather still could take it apart at the age of 93 while half-blind. Handled with one arm like it was nothing. He Had m/31 as his personal weapon as was a good shot. He said that his gun needed to change 3 barrels for his weapon. So quite a few bullets were needed to be shot to damage the barrel. Something interesting was that when he opened fire he needed to take cover and switch positions many times as Russian knew the sound and knew that they need to silence the one shooting. So you got a good gun but was target painted too on you.

[@Ass_of_Amalek]

yeah I have heard of prices like that, and as a violin maker with an interest in guitar making (both of which use expensive woods, especially guitars), it seems to me that gun people are getting ripped off BIG TIME with wood prices. nicely coloured walnut is one of the most expensive temperate climate woods, but it is NOT one of the most expensive woods, and even the most expensive woods (maybe nonsense crazy stuff like pink ivory, australian buloke, mauritius ebony, exceptionally large trunks of african blackwood, snakewood) has no reason to cost $5000 for a rifle stock blank. a reasonable price for a straight-grown flawless dark rifle stock of walnut should be in the $50-200 range. even that are specialty wood prices for individual sale, not how a factory would buy wood. curly grain is not that rare and not universally more desirable, it should not cost more than a 100-200% premium. truly exceptional pieces that combine straight or clean curly growth for structural strength in the relevant parts with burl figure or such at the base of the stock might in principle be reasonable to sell for $1000, but really only when those are also seasoned for 10 years to make them ready to use despite their inherently higher tendency to warp and crack. $5000 makes no sense, walnut is just nowhere near rare enough for that due to its extremely widespread commercial cultivation (as opposed to many more expensive tropical hardwoods that have no use other than timber and are a finite resource coming only from primary forests). walnut is a popular wood for many applications due to its colours, and perhaps the best choice for guns due to its favourable combination of extremely low shrinkage/warpage, moderate density, and high toughness, but there is a really strong supply of it that's certainly keeping prices much lower than that outside of gun circles. walnut is somewhat common on guitars, and I know that it's a low to mid price wood on those.

When the NCOs and COs checked the equipment in the last day and found out that people didn't have all the gear (some lost, some they didn't bring with them) they took a number of the missing items. The next march (or yomp if you're british) the ammount of missing items within the platoon equaled the number of landmines the platoon had to carry with them (each being 10kg or something over 20 pounds). It was almost one landmine for every conscript (around 40 guys). They didn't need to repeat this practice, in the next exercise everyone had the gear that was orderd.

I lived in Finland for two years decades ago, and since then have had a great interest in Finnish firearms.

I actually made the trip three times, determined to buy one, but each time talked myself out of it. Along with my basic concerns about how the gun would function having been altered to semi auto, it just did not look or feel "right". It felt muzzle heavy and unbalanced, although I don't know if that was actually true or just a psychological reaction to the extra length barrel. I think I just felt like I wouldn't be getting a "real" suomi gun, but some pieced together Frankenstein version. I made a fourth trip back, and by that time they were sold out. Having now watched this video, and having my concerns about the semi auto versions built up from parts confirmed by an expert, I'm glad I didn't buy one.

[@StPaul76]

For what I've read from Arma Fennica Lahti designed the chamber of the weapon a bit oversized to ensure reliable feeding and timed the cycle as such that it would actually fire the round slightly before it was completely in battery thus sealing the chamber almost "hermetically" as the case sort of fireformed itself in the chamber. Also not known outside FDF is that the M31 was designed to fire a specific 9mm cartridge that was only to be used in handguns (Lahti pistol, Luger..) in emergency. Nowadays it would be rated as +P+. 124gr ball at about 1350fps @the muzzle out of an M31. The extra punch was to cycle the massive bolt properly and fas enough and as a bonus it gave the weapon a bit more reach and penetration on the field.

I believe the reason why Lahti made a quickly changeable barrel was that during long fire fights the barrel could often get overly heated making the gun less accurate. One way of recognizing a true hard boiled war veteran was the burn scar he had in his palm from changing barrels 😎

I have a select fire John Stemple STG-76W (KP-31 copy) and is one of my favorite sub guns in my collection. I attest to its superb build quality and reliability.

Thank you for titled this clip in Finnish! Great video.

The "Tikka Koski Iron and Wood Company Limited" must be one of few statements ever that is longer in English than in Finnish. When buying home electronics where I live, the manual usually come in all Nordic languages. The Finnish part is always substantially thicker than the Swedish, Danish or Norwegian parts.

[@reinokarvinen8845]

That is because Finnish is more precise

[@Mongo63a]

Swedish m/45 magazine probably one of the best SMG magazines ever put into production. Looks like the ejection port deflector was for a lefty shooter? Given all the trouble they went to on the charging handle for debris intrusion, you would think they would have designed some sort of ejection port door. The M3 GG is the only open bolt SMG I can think of with one though.

[@Doppeldropper]

Mongo63a ...no need for it, no risk hitting your face in standard configuration at all shooting it lefty. This "reflector" looks really bad on this gun and is totally unnecessary :(

[@barthoving2053]

The bolt sealed the ejector port most of the time and was a more precise fit as it was milled then the stamped M3 GG.

[@hansmueller3029]

I really like Ian's style. He just loads, takes the safety off and gets it on.

[@JackOSUrulz]

9mm subbie? Used in WW2? Finnish design? This is gun porn at its finest... What’s crazy is I was reloading D166 rounds for my M39 this morning and this video popped up....had to stop and drink some coffee and have a peek...

[@jurajokasa834]

yeah man D166 for M39 is the best ammo :) or if you want cheap commercial loadings buy 203grain softpoint Brown Bear steel cased ammo :) works too

[@hansmueller3029]

Does that ammo have a 53 mm case ?

[@garryfromwallmart4263]

Probably mentioned here somewhere in the 1900 comments... But the charging handle location also is in the place of where a bolt is on a rifle. For some wierd reason early scandinavian weapons had a focus on beeing "Conscript friendly" meaning "Oh, HMG, LMG, MP or Rifle? Learn one motion and you can use them all!". Didn't take long until the fault in the logic was seen. But wasn't just Scandinavia using this logic.

[@paavobergmann4920]

"kosKInen..sorry: KOskinen..." Yes! Yesyesyes! Finally someone!

[@pavlik_morozov_1932]

When I did my military service in 1969, this weapon was still in use in the Finnish army. At least when shooting with a muzzle brake it was very stable. You can easily imagine how quickly a row of new 9 mm holes appeared in the neighbor's vatnik during the Winter War...

[@ADRay1999]

Didn’t Simo Hayha “The white Death” used one? (And yes I know he used a Finnish type mosin nagant)

[@MrBonjoboy]

Yes he used one, but mainly he used m/39 rifle.

[@Eternalnight198]

Simo Häyhä primarily used a rifle although he is also credited with large number of kills with a submachinegun too.

[@Guro512]

He used M28-30.

[@Makedeth]

yes, over 200 kills with this SMG. well, the m28 model.

[@jessekaartinen]

I visit the same shooting range in Iittala occasionally. Great channel, I've been a fan for a couple of years now. Although a Finn, I like the variety of nations featured and expecially the more "weird" weapons you explore. Keep it up and thanks for keeping Finland on the map. We still exist.

Btw, "Suomi" is the name of the country in Finnish language whereas "Finland" is the name in Swedish language. For historical reasons, the Swedish version of the name of our country is used in international contexts. In some official contexts the name is said also in the form "Suomi-Finland". I have met tourists here in Finland who asked me what on earth the word "Suomi" means!

[@jussiturpeinen2509]

suomi-> suo maa -> swamp land :) my theory on the name

[@66Flux]

@@jussiturpeinen2509 I'd bet you're right, but those tourists had no idea that the word "suomi" is the name of the country!

[@jierdansix8356]

Suomi -> suo maa theory is complete fabrication. The suomi-word comes from an much more archaic (older) word from the age when Finnish language was developing. For the life of me, I can not remember that word or it's correct linguistic spelling. I know this because I got throughly scolded by my wife (MA in the Finnish language) when I uttered that theory out loud few years back. A very good lesson about linguistical etymology is that you simply don't and never should intreprent the words etymology on how the word looks (spelled/vocalized) today. Words are very often older or have changed meaning or have had doublemeanings even in resent (1800-1930 history). For example the word "pohtia" which today mainly means the act of thinking or pondering was used to discribe the act of separating grains from trash (literally jyvät akanoista) with a special tool called pohdin. The word pohtia is much older than we think. - scolded hubby and a (not yet published) historian

[@tomi_9212]

And also SF means -Suomi-Filmi Oy- a Film corporation, that was founded 1920`s controlled film industy/ publishing. records are now controlled by National Audiovisual Institute.

[@Aurinkohirvi]

The most probable origin for the words Suomi (Finland), Saame/Sabme (Lapland) and Häme (Tavastia province) is Proto-Baltic loan word *zeme, which means land, people. It's pretty much concensus that's the origin for the word. In the Novgorod chronicles the Russians call southern coast Finns as "Sum" and the Tavastians as "Jem." The name "Finn" and "Finland" has a Gemanic origin. Its root is with the meaning of "wanderer," which Germans used the peoples living east of them (now known as Slavs, Balts and Finnic peoples), as these people practised still slash-and-burn agricuture and hunter-gathering and were more mobile than Germans and Norse who were field agriculture practising. Tacitus, the Roman historian used the name "Fenni" in 98AD of people in North-Eastern Europe that by description could have been saamelaiset (in English Laplanders, the Sami) people. One Viking Age (about 800AD - 1050AD) runestone in Sweden has the word "Finlont" and one in Gothland has "Finlandi," both different forms of Finland. In Old High German language (spoken 750 - 1050AD) by the continental Germans the word for the wanderer is "fendo" and "vende," and the eastern people were called Wenden/Winden (in English Wends) and their homeland as Wendland/Windland. The Romans called these people as Veneti and Venedi. In Finnish Russia is called "Venäjä" which is a loan word for the Germanic word, Proto-Germanic possibly.

[@dagreynolds8013]

I was issued this gun in The Norwegian version of BUDS in the 80's. However, we had a 45 round box mag. Just like most well trained units, we fired single shots quickly rather than full auto. Accuracy for an open bolt gun, is amazing. Well ahead of its time!

I have a semiauto build, but waiting until there is snow on the ground before I film a review. Do you have any good leads on coffin mags (I have a stick and two drums... Would like a coffin mag that I don't have to pay to have shipped from Germany which is the only thing I ever see on GunBroker).

[@mattb.2359]

I have one, and don’t have the “speed” loader for it. I bought my coffin mag at a gun show for too much money.

[@MilsurpMikeChannel]

I have a speed loader.... I hope it works.

[@b.butcher82]

The 36 round mags work best with mine. Didn't have much luck with the drum even after increasing the spring tension.

[@MrHamanen]

In the army I did shoot with Suomi kp. And also, in army again, we had this gun with round magazine inside 50 bullets, when we were in guard. Could you imagine now a young (19 or 20 years) man carrying a lethal weapon and then sent him to a dark night walking there alone being afraid of all scary noises you hear?

[@RedXlV]

I remember reading somewhere that Aimo Lahti actually thought the designer of that muzzle brake should've been court-martialed for sabotage. That's how opposed he was to the idea.

[@WhattAreYouSaying]

Absolutely love the Suomi. I have 3 of them...2 Finnish ones and one extremely rare Danish Suomi M41.

[@janiperttila8049]

The Finnish snipers didn't utilize the Suomi MP in sniping. They may have used one when fighting as an infantryman during enemy assaults. Simo Häyhä is famous for this and is probably what the author of the video meant.

[@KiviTinppa]

I was hoping Ian would have explained why the bolt head is so much narrower than the bolt body. Anyway a great vid!

I have a Tikka T3 Lite in 30-06 and yes has a bit of recoil for the caliber and it is one the best guns I have ever had

[@juhomaki-petaja]

Just heard that my uncle (continuation war veteran) said that they taped two box mags together. Drum was too slow to reload. And Suomi was used mainly in semi auto, because no one could carry ammo that it ate in full auto.

[@jimmydesanta1363]

cant believe how straight that shoots for a sub-machine gun, zero recoil

[@dmg4415]

The Carl Gustav mags, You take a stick some electrical tape, connect them into a V-form, then you have 72 cartidges a hand, just a second to change. You put in the left hand magazine first, then it was easy to change. This works for most weapons even hk g3 (Ak4).

[@Targetpopper]

Super fun gun. My buddy has a post sample. Very accurate and magdumps can be controlled like a laser pointer.

[@okaro6595]

Actually Aimo did not leave, he had his day job in at VKT. The submachine gun was his private side project. Lahti made scrap like LS-26 and the M/27 rifle for his employer and the good thing as a side project. He ended up making close to a million euros in today's money as royalties. The SMGs had to be modified to accept the Swedish 36 round magazine. Same was done to M/44. Btw the 50 round magazine is also a Swedish one. The major innovation in the bolt was to make it narrow in the front. This was to reduce the chances that the cartridge turns sideways while feeding. "Lukko ja piippu irroita!" The idea that a 12 year old kid buys a rifle the army had surplussed just ten years earlier would be unthinkable today. Back then only magazine rifles were under license.

[@mottee]

It is not fully justified to blame Lahti for the defects of the LS-26. He wanted to design a gas-operated gun but the old farts in the Army insisted the gun to be recoil-operated. The "S" in the LS-26, Major Saloranta, fiddled with the blueprints without negotiating with Lahti. And because of the incompetence of the production facility, it took a long time and a personal intervention by Lahti before they could churn out functional guns. Later Lahti designed an excellent gas-operated "Sampo" general purpose MG but the war ended before any significant quantity of them was produced. And after the war the Army had some 9000 captured DP-27 LMGs in their hands, so the Sampo never went into large scale production.

[@HappyBeezerStudios]

Now I want the full kit. With frontgrip, bipod and bayonet. And the deflector with matching colors.

[@RockerFinland]

I've heard those guns killed many Soviets back then (Suomi M/31). If I just remember right Simo Häyhä (the sniper legend) killed 200 soviets with on of those.

[@pouch2598]
