Just some helpful hints.
1. Focus on the Front Sight when shooting the rear should be a little fuzzy.
2. Use only up to the first joint or the first pad of your trigger finger to pull
3. Steady smooth straight through trigger pull to the rear!
4. Also have a friend live load a round in the chamber from the magazine and
dummy load the pistol with a empty magazine so you will not know if the
chamber is loaded with a live round or empty. This is a good test to see if
you are pre anticipating the weapon recoil, or possibly snapping the trigger.
This is an excellent drill!
