I don't know of one, but a carbine would be neat IMHO. I would think that due to the pressures involved, and bottle neck design, some sort of locking action might be required. In a straight blow back action, I wonder if the .357 SIG case might come out looking like a straight sided .40 S&W type case............ymmv
