​In the late 1930s, Sweden developed a four-column box magazine (often nicknamed the “coffin” magazine) with a 50-round capacity for the Suomi submachine gun. It was designed as a cheaper and lighter alternative to the standard 70-round drum. Finland purchased the license and launched mass production in 1941, manufacturing over 120,000 units in hopes of simplifying troop equipment.

​The design, which featured two wide internal compartments that funneled into a single feed point, proved too delicate for harsh combat conditions. These compartments and their tapered springs were extremely sensitive to dirt and physical impact. The spring coils frequently tangled, causing feed jams—especially when the magazine was fully loaded. On the front lines, it gained a reputation for unreliability, as even slight deformations of the casing would cause the cartridges to bind.

​Due to widespread complaints from the field, the Finns halted production of these magazines by the fall of 1943, reverting entirely to drum magazines. Post-war attempts to improve the design (including reducing the capacity to 45 rounds) failed. In the 1950s, they were replaced by the more reliable 36-round double-stack magazines from the Swedish Carl Gustaf, and the old four-column “coffins” were eventually scrapped for metal.

Why add a gun from a neutral country that didn’t fight in the war, and didn’t sell this perticular gun to anyone or send it as aid to anyone…? Just use the actual Finnish gun, rather than a foreign liscence production of it.

Voting no because of that. Magazine is fine, but not this gun.

If you didn’t intent for your suggestion to have this meaning, then I suggest editing your suggestion to make that clear, and remove any mention of the Kpist m/37.

Thou shall take this with not grain of salt but with mountain of salt.

I know there were fully equipped volunteer units and m/21 light machinegun for example was supplied to volunteers & bought / borrowed ? by Finland during winter war.

Anyway, feels bit odd that sweden would only partially supply the volunteers.

I hope you’re not trying to lecture me about my own country’s wartime activities.

  • Swedish military aid simply did not include SMGs.

That’s the truth of the matter.

  • This is because of the simple fact that the pre-WW2 Swedish military did not embrace the SMG. That was done during the course of the early days of WW2 and the Winter War.

As such, they had no SMGs that they could afford to spare. Just look at the years of official adoption for the various SMG models in use by Sweden, and then assume a minimum of one year before they get into the field. By the time WW2 kicked off, Sweden barely had enough SMGs to rub two of them together. Another simple truth.

  • Difference in ammunition.

Sweden was using the 9×20mm Browning Long cartridge, which made their weapons incompatible with Finland, who were using 9×19mm Parabellum. This would have made Swedish SMGs in Finland militarily very unuseful, if a small quantity of guns were to be sent anyway.

  • Manufacture had barely gotten off the ground in Sweden by the time of the Winter War’s start.

After the end of the Winter War, Sweden bought another batch of Finnish-produced SMGs, because Finland had a surplus whilst Sweden did not. Finland were already avid users of SMGs (especially in comparison); they needed heavy weapons more.

In fact, manufacture of the licensed SMGs was so inadequate for just their own needs that Sweden felt it was forced to fully switch to 9×19mm Parabellum and begin buying MP 35s from Germany. And then, they developed their own home-grown, cheaper style of SMG by the war’s end just to cope with domestic demands.


These are the facts of the matter. No Kpist m/37 guns made it to Finland as war aid, and pre-WW2 large scale adoption of SMGs was not as common as you might think it is.

If you think this is wrong, I’d urge you to provide evidence to the contrary, rather than baselessly speculate.

If the Swedish armed forces did not release m/37s (as they did with other weapons), then Finland did not receive them, full stop.

Well, it can be given at
Br 2 - 20 rounds
Br 3 - 35 rounds
Br 4 - 50 rounds
Br 5 - one with suppressor - 71(?) rounds

Swedish here exactly a magazine for 50.
which was given also to a finnish and german corps in 1942 at the northern front. @_DELAVR tell if I’m mistaken.

The thing it defiantly was taken as trophy and now can be seen in a state museum

Neither they didnt really need them, did they ?

Applies to alot of weapon brought from sweden.
Fins had no domestic production for 6,55 mm x 55 either, yet alot of these guns did appear in finland either as aid or with the volunteers.

First off, I’d like to point out that the 36-round magazine for the Suomi M31 was developed after the war. It’s also worth noting that early 20-round magazines could actually hold 25 rounds in practice (we already have weapons in the game that hold more rounds than specified in the manual).

The Suomi M31 submachine guns delivered to Germany were equipped only with drum magazines: “During the visit, Mannerheim decided to present the Germans with a gift of 120 new Suomi submachine guns, including five drum magazines and 2,000 rounds of ammunition for each weapon. These were intended primarily for use by German troops operating in Finland. In addition, the Marshal (Marski) decided to personally present Hitler with a Suomi submachine gun equipped with a dedication plate, a carrying bag, and five magazines.”

However, if it is fundamentally important to you to give this weapon specifically to the Germans, you could provide the MP 746(d) with a 50-round magazine. The MP 746(d) is the Danish licensed version of the Suomi M31, which the Germans captured after occupying Denmark.

Show me evidence of Kpist m/37s being in use by the Finns or sit down.

You won’t, because there are none.

By any chance, is there any information regarding the use of the Ag m/42 rifle in Germany, or is this just an error in Russian sources?

I would be doubtful.

My understanding is that the Ag m/42 was developed from examples of SVT-38 rifles captured by the Finns soon after the end of the Winter War. As such, I don’t doubt that the Finns were part of the development process somehow (Sweden often utilized Finnish experience when designing weapons or adapting military doctrines), at a minimum they were supplying Carl Gustaf’s with the rifles after all and more cooperation is not impossible. And if so, then it would be the Finns who had access to some (either actual examples or technical information), rather than Germany.

Other than the Finnish lead, I don’t think the rifle made it outside of Sweden during WW2, except for Norwegian troops trained and armed in Sweden. Now, these Norwegian did eventually return to fight the Germans at the end of the war, and as such some of there rifles might actually been in use in wartime service (fighting in conjuction with Soviet forces up in Finnmark, for example).

Maybe some Ag m/42s were captured by Germany and sent south to Germany for study…? If so, I am unaware of any such examples. Not impossible, but I feel like at the last months of the war (winter 1944 onwards) that would be unlikely (the logistics of taking a couple of captured rifles from Finnmark to Berlin as the German war-effort is collapsing and German occupation forces in Norway remained isolated makes the prospects very dim indeed), and I would remain sceptical without further evidence.

As people have already mentioned, the 36 round magazine is postwar. I’m just replying to this particular message for context to my response:

I have read on secondary sources mention of some Suomi KP/-31s being modified with MP.40 magazine adapters to use MP.40 32 round magazines, kind of like the MP.41(r) but minus the additional barrel change to accommodate 9mm, supposedly both by the Finns and Germans independently. It’s plausible, but I haven’t seen any concrete evidence, but I think it’s worth investigating for a potential BR 3 SMG for Germany if they made these sorts of modifications.
