I doubt you could outdraw someone like that. Even if your draw is .9 seconds, the average human response time is .25 seconds.
This is why you should train to MOVE FIRST and DRAW SECOND. Immediate movement off the line of attack is your protection. As soon as you're in motion off the line of attack, THEN start your draw. If you try to do both simultaneously (start to move AND start to draw) then you won't clear of the bad guy's muzzle as quickly and you may also telegraph that you're about to do him harm.
