It would be a custom option, but it has been done. For those wanting a 45, and for those shooting WB, it would be possible to shoot the same ammo in rifle and 1911, and SAA. It would seem a good length for shorter barreled handy carbines, short stroke levers. It would still have serious power, would be cheap on surplus type ammo. It was invented 30 years earlier than the 357 mag that is all the rage in CAS. Would seem to have everything for a 45 shooter, other than the fact that nobody chambers a factory lever.
So what do you think? Any reason not to do it?
