5.7 is known to be pretty terrible for its "stopping power" for lack of a better term. Its a handgun round design to penetrate body armor. In doing so it had to make sacrifices in bullet dimensions and weight. It performs similarly to a .22 magnum round which is a frankly wimpy cartridge meant for small game like rabbits.

So 20 rounds to stop a human isn't stretching the truth too much.
