Preparation: Sight in on steel plates during practice. Get the sight picture you want, remember it, and use the same sight picture in the match.
Always call the second shot on paper targets before going to the next target. Avoids infuriating mikes.
See what you need to see to make the shot, let the gun go off, call the shot as it goes off.
1. A solid grip and index is better than a fast draw.
2. Get on the same squad with other revolver shooters; misery loves company.
3. Don't think about the trigger.
