Granted, it's made in Taiwan and it's only 4.5mm (.177 BB) instead of 9mm. The "Authentic Weight, Balance, and Handling" is a bit of a stretch, the 9mm is definitely heavier even without a loaded mag and comparatively top heavy as well. But aside from the slightly thicker magazine base and red dot for the safety, the CO2 version is a dead ringer. Blowback action so the slide reciprocates when fired, and holds back on the last shot.
