Do not get in the habit of focusing on micro accuracy in the middle of pulling the trigger. If you practiced to be fast at pulling the trigger without moving the sights, live ammo is merely a confirmation and your impacts will tell you if you did it right. Realistically, nothing is different about that trigger pull except what happens after the trigger breaks. Of course you want to hit your target, but don't crap on all your practice by going back all the way to Turtle pace shooting. Basically, try not to pull the trigger slower than you do in dry fire practice.
