It was also pretty popular with Merrill's Maruaders in the Pacific, and if you know where to look, you can even find 40 round magazines. I'm quite fond of the little weapon, 'though mine's been upgraded a little from original specs....
Very nice!
At least one company makes a .30 Carbine revolver that makes a nice companion piece, though high on the muzzle flash. Better than a bayonet!
