When the Swedish military decided that 1937 seemed like a pretty good time to be getting some new submachine guns, they arranged to purchase a version of the m/31 Suomi from their Finnish neighbors – which they called the M-37. Since the standard Swedish military pistol (the Husqvarna m/07) was chambered for the 9x20mm Browning Long cartridge, they got a version of the Suomi chambered for that round. It used a rearward-sloping (to prevent rimlock) quad-stand magazine that held 56 rounds.
Shortly after this purchase, however, Sweden bought a number of other foreign-made guns, including Walther HP pistols and German submachine guns in 9mm Parabellum. This was a more powerful and more modern cartridge than the 9×20, and so the followup licensing of Suomis reverted to 9mm Parabellum as well, with the designation M-37/39. While the basic mechanism of these is identical to the Finnish Suomi, they differ in some details, including barrel length, charging handle contour, and stock profile.
“They can deal with it…”
I laughed – thanks Ian, it cheered up my day
Great presentation

If Ian had one of those daft social media thumbs up things on his site, I would have used one. When Finland beats Sweden at ice hockey Finland’s birthrate increases 9 months later, and Sweden pretends it didn’t happen.
I guess I will just have to “deal with it”…
Heja Sverige friskt humör det är det som susen gör!

That spring is relatively stiff (small diameter), hence the high rate of fire. MP38/40 is little more advanced in that way. The gun is certainly solid built – like Volvo.
“9×20”
It was also used in A.T. (Arsenal Tallinn) which was derivative of Swiss Brevet Bergmann sub-machine gun:

if I understand correctly (translator) it has two stage trigger (shallow squeeze – single, deep – auto)
Estonian forces also later decided to bought SUOMI sub-machine gun in 9×19, but producer of this sub-machine gun redesigned it for 9×19 to compete (prototype was build), but further development stopped after Soviet occupation.
Is it just my impression from the camera angle or is the trigger a bit of a stretch for a normal firing grip? It looks painfully far forward.
