You all need to step away from the keyboard.
You are getting confused. There is no conflict. Libby has no problem calling a semi-auto, like John M. Browning's creations, a "pistol". It's revolvers being termed pistols that gets his dander up. My fahter in law, a little older the G. Gordon, used the terms the same way. He had several of each in his gun safe, but the one beside the bed was a .45 ACP pistol.
Are we done now?
