We've pretty much standardized on 9mm as the SMG cartridge with some deference to 45acp. Yes there were/are other cartridges (32acp, 380acp, 9mm Mak and a few others); but sticking with PISTOL cartridges there are no magnum SMGs...or are there
Kriss makes a 10mm Vector SMG. Before that there was the M1 Carbine, which by definition might not be a SMG; but seems to have been used in that role particularly in the theatre made Advisor Carbine model. Perhaps the Soviets beat us all to the MAGNUM SMG cartridge with 7.62x25
I always thought 357Sig was a great idea. It fit in 9mm/40SW size magazines and being bottlenecked fed without issues. It also is flat shooting, at least as much as you can say that for a pistol cartridge. I have seen a novice shooter make 200m body shots using a RMR'd Glock 35 with a 357 Sig Barrel.
This was at 100m using sand bags as a rest, just to say I could do it!
BUT it was after a lot of rounds and a lot of targets.....and I probably couldnt do it again
So why a Magnum SMG when we have short ARs in 556 and 300 Blackout? Well, my thinking is there are more places for a (semi) SMG or braced pistol, than a Rifle, particularly a short rifle in 556, for a civilian. The blast difference for one but also the size AND the size of the magazines, (two 30 round 10mm mags ac be carried in the space of one 556 mag). A stocked or braced SMG (semi) in a magnum/intermediate pistol cartridge (10mm, 357Sig, 762x25 etc) is surely capable of being combat effective out to at least 150M, with "half the blast of 556" from a short barrel
