I always caught the link as just part of my follow through. The front sight needs to come back too. Then after firing finger comes off the trigger and trigger finger goes on index point on the frame, and then if possible, scan and asses.
The way you operate your pistol should be the same for the most part when shooting on the move. The way you follow through should definitely be the same. Do you really think that you are suddenly going to be able to shoot in a completely different manner than how you trained in a "serious situation" as you called it? If you are not on target and actively engaging you should have your finger on the index point and out of the trigger guard. When actively shooting on the move there is nothing wrong with using proper shooting technique.
What does your finger usually do after you have fired a shot?
