Oddly, the ones that are pretty good at defeating soft body armor are mediocre in living tissue. You could argue that it's a tradeoff, and works better than something that doesn't get through the soft body armor at all, but it's pretty meh, in my opinion.

There's bullet design and there's cartridge design, I think. The original SS190 steel core 5.7mm bullet was intended to defeat soft body armor first and furemost with all other considerations secondary. By the standards of pistol bullets it's really good at that one thing. The SS190 bullet frequently yaws in soft tissue but it was not designed specifically to do so. Projectile yaw is by its nature an inefficient and inconsistent wounding mechanism anyway.
The 5.7mm cartridge, particularly when fired from a pistol, as opposed to a carbine or submachinegun, does not generally develop enough kinetic energy, even at the closest distances, fur consistent effectiveness in the personal defense role fur which it was, ironically, designed back in the 1980s. Velocities are high but the bullets are very lightweight and in my opinion the kinetic energy just isn't there. About twenty years back there was a brief fad fur the cartridge among USAian law enfurcement, who really liked the firearms until they had to shoot bad people or rabid pitbulls with them, then dropped them like they were radioactive.
