What technique should you use to hold a gun when you need to fire quickly?

When you need to fire quickly, use the "high thumbs" grip technique. Ensure your dominant hand is firmly around the grip, with your thumb positioned high on the back of the frame. Place your support hand on the front of the grip, using your fingers to wrap around the dominant hand while pressing the palm against the frame for stability. This grip enhances control and allows for faster follow-up shots.
