This is the schtick to draw quickly and to act first at the start of a fight.
For the first Sequence of any fight, add an additional d6 to your Speed roll for Initiative. If you add to your Initiative result in this manner, you must draw or attack with a gun as your first action of that sequence. You can still use ActiveDefense out of sequence before your first shot comes up.
This schtick also allows you to draw a pistol or other small weapon that normally takes a single shot to draw in no time, and to draw weapons that normally take three shots to draw in a single shot.
