The US .30 M-1 is a Tweener: supersonic, but not high-velocity. Size and recoil both favor it as a handgun cartridge.
If memory serves, Ruger Single-Six and Thompson-Center Contender were both chambered for it.
I always wonder about such switchings though. Should not powder burn rates be suited to barrel lengths?
It seems to me that a handgun firing a .30 M-1 would have excessive powder waste and muzzle blast. Conversely, it seems to me that a Thompson M-1928 or M-1 would benefit from a slower-burning powder in .45 ACP.
It was the Ruger black hawk the they chambered the 30 carbine round in.
It does in my opinion have excessive muzzle blast with factory ammo.
If one hand loads one can optimize the powder selection.
