I've done that in half the time, one handed, while moving. Seriesly, it's not that hard.
He is talking about from the holster. Depending on the distance, the Front Sight school in Vegas, for example, uses test times from .9 sec to about 1.8 sec for a controlled pair to the thoracic cavity from the holster and under a cover garment. That takes some practice to get to, and adding movement makes the shooting way less accurate. Its all doable with enough training/practice, but its not “easy”.
