It's a sensible cartridge. Handguns don't win wars, and most of the world's militaries are most familiar with 9x19. In addition, it's light to carry and easy for beginners to shoot, while having decent power and great capacity.
I second that senitiment and its coming from someone who prefers larger calibers.
There is nothing
wrong with the 9mm Parabellum as a service cartridge.
I'll add one more item to LawScholar's list, on hand supply. Why would NATO switch to a different handgun cartridge, when they have millions of rounds of 9mm in stock?
