the .45 ACP has 518 ft/lb of kinetic energy at 1,080 ft/s
the 9mm NATO has 519 ft/lb of kinetic energy at 1,430 ft/s
the 5mm hits with just over 3 times as much kinetic energy at just under 4 times the speed. you tell me which one you think hits harder.
the design of the 5mm enables it to fly farther and retain its kinetic energy for longer distances as well as allowing the capability to penetrate body armor.
even the 9mm "NATO" (an overpressure version of the parabellum), standard in NATO 9mm rounds hits harder than the .45 ACP and flies almost 1 and a half times as fast.
Admin. Excessive use of icons is to be avoided on here. It is also good form to quote multiple/single sources when quoting material.
You do appear to have missed the point that my comments were also rhetorical and not literal - hence the hanging sentence
