I don't expect so see any information on exactly how the Secret Service or and special ops. folks deploy the 5.7, but I'd guess that it's in submachine guns, fielded by a portion of a team that also has other weapons. One 5.7mm hit probably doesn't match one 9mm, .40, or 357 SIG hit. Four 5.7mm hits probably top one pistol round. if you've got a guy in body armor, the 5.7mm probably beats other pistol rounds. If you have a team shooting at a threat, and you have two guys shooting .357 SIGs, and one guy with ammor peircing 5.7mm ammo, all of your bases are covered. That said, if you said this thing beats a .22 Magnum by 25%, I'd be currious to see how it performs in a regular jacketed configuration. I'm not sure velociy beats weight, but if you're getting close to 2,000 fps with a 33 gr. bullet, I don't know. That's a lot of velocity.
