Confidence in your trigger control? I was at the Canadian Nationals a few years ago shooting in the next bay to a gentleman from AB who had been the Canadian Free Pistol Champ for many years. He has been attending the Nationals since the late seventies and represented Canada around the world.Many will know of whom I speak. As I was shooting next to him I was watching as he TAPS his trigger finger on his free pistol trigger while sighting on the target. I watched him tap the trigger about 10 times before firing the shot. Tapping a trigger that is measured in ounces says a lot about your confidence in your trigger control. That man is a shooter.
Possible with a lot of overtravel in the trigger adjustment. Would be disastrous if pistol has a short overtravel setup, as shooter would more likely jerk sights off the aimpoint.
