The 9mm Parabellum was designed just for Combat and War
I'm not sure you're correct. The 9MM was originally known as the 9MM Luger. I'm not sure when parabellum was attached to the cartridge and why. It was first used in combat in WWII, and I believe it was used as a submachine gun cartridge. So was parabellum attached to it due to its submachine gun use?
I don't believe it was designed as a handgun combat cartridge. But I might be wrong. If you know of primary source documents that support your theory, I'd love to peruse them.
