Finnish M31 vs KP44 - SMG Live Fire Comparison

[@jmkorhonen]

This video shows why the M31s were retained in Finnish war reserve stocks until about 2005, whereas all reserve KP44s were melted down by the early 1990s. I recall hearing from older folks who used to live close to the border that when they had to evacuate in 1939 and again in 1944, they'd listen for "the song of Suomi"; as long as it could be heard over the din of war, they knew the Russians wouldn't be moving.

[@Leopardipzg]

The Mannerheim cross reports where the Suomi is used are hardcore. Take for example Emil Pasanen: *During enemy breakthrough attempts in battle of Prääsä on Sep 8, 1941, he defended temporary positions alone when his comrades around him were dead or wounded, and repelled attack of about 200 men, killing estimately 120 of them from his foxhole with Suomi SMG.*

The original Mannerheim cross report actually goes like this: "”Ylipäällikkö on pvm:llä 26.9.41 nimittänyt Vapaudenristin 2. luokan Mannerheim-ristin ritariksi sotamies Emil Pasasen, joka [Suvilahden] taistelussa 21.8.41 konepistoolilla tuhosi kymmeniä vihollisia näiden juostessa taloista ulos suorasuuntaustykin ajamina ja [Jessoilan] taistelussa 27.8.41 valtasi konepistoolia käyttäen erään toverin kanssa tärkeän sillanpääasemakukkulan ja piti sen yksin hallussaan toverin kaaduttuakin, kunnes sai apua omilta joukoilta sekä [Prääsän] taistelussa 8.9.41 ratkaisukohdassa vihollisen läpimurtoyrityksen aikana esti, tovereiden vieressä tultua taistelukyvyttömiksi, yksin konepistooli aseenaan kaksisataa-miehisen vihollisen tunkeutumisen tilapäiseen puolustusasemaan siten ratkaisevasti vaikuttaen vihollisen hyökkäyksen epäonnistumiseen." Not sure if Google Translate will work, but your comment contains quite bit of misinformation.

[@dabbidaa1547]

Long range patrols behind russian lines caused a lot of casualties to pursuing forces with these things. Usually 80 - 100 % of the patrol was armed with these and the rest with rifles to maximize firepower for the group. Imagine being ambushed with 15 of these spraying at you out of nowhere.

No worries; sorry if my response sounded overly jerk-ish, it wasn't the intent. That aside, the Kp44 is based on the Soviet PPS-43, which fires 7.62x25, so it isn't that far out of the realm of possibility to wonder if either of these fired a wimpier Soviet round. :)

There was a very interesting historical documentary that was made about the Winter War several years ago which I thought was very well done, and of course, also get the movie TALVISOTA. (Be sure to get the extended unedited version.) Some of the battle scenes are truly cataclysmic. The Winter War was a Zombie Apocalypse!

[@machintelligence]

I believe that itchy trigger finger can be successfully treated with cortisone cream.;-)

[@sethrich5998]

You bring up an interesting point on fire rate that I often mention. Think of recoil/muzzle rise as a sine curve, in other words it goes up and comes down repeatedly. Having a high rate of fire getting multiple rounds on a single up motion can be controllable. Also having a slow rate of fire where each round waits until the muzzle rises and dips again is controllable. The worst scenario is in the middle of those where a round is fired at the apex of the curve each time.

[@Kumimono]

I gotta say, the sound the 31 makes fills me with movie-induced patriotism. I gotta watch Winter War tv-series, again, one of these day. And The Unknown Soldier. I'm a mannequin for Tikkakoski....

KP44 did not replace The Suomi. Only the first order of 10000 were made and even that after the ear in 1945. Suomi remained in the reserve arsenal until the mid 90s. When I was in the army in the mid 80s we were trained for it and this was not to give some historic perspective.

[@cannonball666]

[@maximthemagnificent]

In the 80s I read about a UK firearms designer who added an electronic delay mechanism to some automatic weapons to find their resonant firing rate for maximum control-ability ("gently rocks in your hand" was how the end result was described). I wonder if the compressing air issue in the rear receiver on the M31 might offer another way to attain that, with a valve altering the rate of fire. It's already controllable, but for another design, perhaps, although a sealing system might be required owing to the looser tolerances in most guns.

[@timomastosalo]

Heard that around 30 men equipped mostly with Suomi kp could slaughter a company (120-150) of enemies in minutes in an open snow field. The enemy couldn't run in the snow. So fast the enemy could barely return the fire, and then so rarely killed any of the ambushers. Of course it had to be a could ambush spot, didn't always happen so cleanly. But with that rate of fire of the Suomi kp, and multible shooters, it was doable with a shock start. Might be 30-40 enemies down right after the trigger push and then just press on to the closest and most active looking enemies, and soon it was the last 50 left who were beginning to find cover, but too late. Then the last 20 and you might get some own casualties with these last 50 enemies One guy has even recorded having done it alone, when he shot from cover in the forest edge, and the enemy company came in a line through thick snow. The leader of the column trampled the path, so they couldn't run anywhere, and walked dead on towards the ambush. So at first only a few guys could aim the shooter., and they were the first targets. The shooter had multiple magazines that take 70 rounds, but maybe 30-50 rounds was a more realistic way to fill the drums, the full drum wasn't that reliable. And he did have one guy to load the drums, or was there actually more than one loader: slow job to fill the drum with 30 9mm rounds. He did get a scratch in the head, shot by one enemy who had find a bit of cover, and so was unconscience for a few seconds. But he came around again, and continued shooting until he had mowed down the whole company. They made a scene of it to a movie called Tuntematon Sotilas (Unknown Soldier), based on a book with the same name (by the author Väinö Linna). But the scene is based on a recorded war incident - not just in the book. Only the name of the soldier was changed, like all the names in the company where the author had served. There are some artistic liberties in the book of course, but all its battle scenes happened to someone in the company, or who faught alongside them. For example an AT trooper was hit in a attle scene in the book, and one of the ncos in the author's company took his satchel charge designed against tanks. In the book he goes and blows the tank, in reality it was the AT nco himself who went and destroyed the tank. Maybe he was just temporarily pinned down, or wounded only very lightly. So the writer added a little drama with the wounding, when in reality the AT trooper was a pro enough not to expose himself much, and did de job.

[@Xerxes1688]

I think that the only WW2 smg close to the M31 Suomi in terms of overall design, craftmanship and effectiveness is the italian Beretta MAB-38A. The MAB doesn't have drums, but the rate of fire is slower, and since the gun is not lightweight, it doesn't jump around. Other than that, they have a lot of similarities: tangent rear sight, barrel jacket with muzzle compensator, wooden rifle-like stock, machined receiver, same barrel lenght, non-reciprocating charging handle.

[@raider762]

Want a M31 Suomi now...

[@Mattebubben]

It would be interesting to see handling wise how the Swedish Version of the M31 (Kpist m/37 for the Version in 9x20 mm Browning Long and Kpist m/37-39 for the 9x19 mm version that became standard) It was built in Sweden under license (around 35,000 were built in Sweden by Husqvarna) and had some changes including a shorter barrel. This results in the gun being lighter (at around 3.9Kg as compared to 4.6-4.8 of the M31) and easier to handle in cramped spaces as it was noticeably shorter, but it would be interesting to know what kind of impact this had on its shooting characteristics (Mainly how Accuracy and controllability was affected).

Great video guys. I like your uniforms that go with your fine weapons. I have fired the Suomi, and the PPS 43. They are really fine weapons. You both have great firing tecnique. I also like the M3 and especially the M3 A-1 more than the Thompson. It is a very under appreciated SMG. However a correctly trained soldier with the M3 or M3 A-1 can really show that it's a myth to call the M3 M3 A-1 a bad SMG. The Finnish M31 certainly compets wel not only as the most controllable SMG of WW-2, but stands up well today to many newer SMG's. However, while not as good as the M31, the KP44 aint bad either.

Ian and Karl a question for you guys - you talked a lot about "quality" in this video being a key determinant between the M31 and the KP44 though the effectiveness of the weapons when compared seems to be about "physics-induced" properties - the overall effect of (1) size, mass, orientation and action of the bolt when firing; (2) resultant rate of fire; (3) overall layout of the weapon and overall weapon mass etc. Would the Finns have been onto a real winner if they'd designed and built a cheap stamped gun that retained those key attributes of the M31 but did away with the quality of manufacture ie milled receiver, wooden furniture etc? Are there other examples from WWII or after that you could cite that get at what I'm talking about? The Uzi springs to mind I guess.

The part you said a higher rate of fire makes a gun more controllable... I can't agree more. Kinda like if you spin something around a point other than its center of mass, the faster you spin, the more stable the thing will be.

[@deepbludreams]

It has to be combined with weight, the Glock 18 fires at 1200 RPM, it only has a effective range of about 7 yards for a reason.

[@mw4222]

I agree. When ROF is so high that the recoil force is too high for the shooter to handle, a high ROF will result in bad stability, however when kept under a certain threshold, the faster the ROF the better the stability.

Doesn't have to be weight though... Could also be an effective brake, or a counter-balance system like that on an AK107.

[@rcbif101]

The Swedish K is very smooth firing, but it is a pound or so heavier than the KP44 which may not sound like much, but for guns that have the CG forward of the pistol grip, that makes a big difference. The Swedish K also has a heavier bolt and I believe it does not come fully into contact with the back of the receiver. The KP-44 does making the action a bit more harsh.

[@rcbif101]

Alistair Shaw no, ppsh has a lighter and shorter throw bolt. It has more muzzle climb because it has a lighter shroud than the m31.

[@wierdalien1]

Rcbif i get that but if you watch the how much the gun reacts to the bolt throw the 44 really moves as it goes into battery but at the same time seems to take forever to get there.

[@brasstard7.627]

Alistair Shaw yes the bolt has a long way to travel that's what gives it the lower rate of fire

[@wierdalien1]

Brasstard 7.62 sure that makes sense but i also am talking about how the long, i suppose lock time but not really to do with the lock time itself, messes with the harmonics of the rifle. If you gave it a stronger spring it would reduce the long time but you still have a long throw

Questions about ww2 SMG Drum mags, as of now i dont think i ever seen one with malfunction. Or is it just a youtube thing?

[@rickytuttle451]

Does the smg (pistol calibre) still have a purpose with the creation of SBRs/pistols with rifle calibres?

Many historians do not know that the Finnish sniper Simo Häyhä 'The White Death' got several hundred of his kills using the M31. The M31 was so good that it is the only SMG that could be used in such a role.

[@Leonidae]

~250ish of his kills were with Suomi.

[@jonahmeert482]

Yeah, they don't because it's not true. Wikipedia is not always a reliable source.

Suomi compared to CZ ZK-383? Even taking into account their respective manufacturing costs?

[@stevailo]

How does the m31 Suomi compare to the beretta M.A.B. 38?
