second, at arm's length, and hand discretely on gun. You can usually remove the .20-.25 second reaction time from such a draw, too, cause you'll be TOLD to take your hand out of your pocket. So, the attacker will have at most .40 second to NOTICE what's in your hand, decide what to do about it, react, and fire. Won't happen, especially if he's EXPECTING to see SOMETHING in your hand and the time he has to react is AFTER your hand emerges, and he EXPECTS you to "hand it over". From the time your gun clears the pocket, until you can thrust it foward, lock your wrist up against your pec and fire is like .20 second(for a reliable hit at arm's length, on the chest). Given the typical clown's need of 1.2 seconds to react, make a ccw belt draw (likely fumbling either the ccw garment or getting a poor grip on the gun) the .20-.60 second of the pocket draw is going to be a great advantage, time in which to BRAIN the gun at least once. No, you CAN'T discretely have your hand on a belt or shoulder rig's gun. Everyone knows what that "move" or stance means. It means that they should shoot you instantly, and they will too, most likely.
