WTB YHM stainless pistol comp in any caliber with corresponding thread adapter. Thanks for your time.

I wonder if you could buy a 40 and then screw a 9mm front end on it and run both? maybe get ruger to sell a barrel assembly seperately? they list on their website barrel replacement for pc carbine at 85 dollars. and hey if a 9mm barrel can be fit and run on a 40 cal bolt than means a 357 sig chamber could be cut.. I know its not the 10 everyone wants but it could be a fun gun.
