Besides, 45 ACP is a newbie when compared to 9x19, 9x19 was introduced several years before the 45 ACP hit the scene.
By that logic, we should all be using .32's. The 7.63mm Borchardt (1893) pre-dates the 9mm by 9 years; the 9mm ParaBellum (1902, means "made for war") only predates the .45ACP (1904, means "Automatic Colt Pistol") by 2.
Then again, I think what you're really saying is, the .45ACP was a natural evolutionary improvement over it's predecessors, the 9mm and 7.63mm.
