Hi, 5.7x28mm ammunition is illegal to import into Australia (though the pistols themselves are legal, dont ask), and I've always wondered about how good of a round this is. Anyone out there with FN57 experience? Very quick round (2200fps) with minimal recoil and a 20 round magazine inside the grip seems pretty interesting. Quick follow up shots should be easy, and with a 20 round magazine you have far more rounds than most other handgun calibres. It's also a lot flatter shooting than other handgun calibres so you could have an advantage at range. Could see it being useful for plinking, maybe even a niche case for carry where carry is legal. Cheers.
