Meant to also say, when you fire it in what you find to be your preferred natural stance, let the barrel return naturally back down to your original aiming point and squeeze off again, don't try to achieve a fresh eye picture each time through the sight blades, the pistol was designed to accurately put down fire in combat situations quickly.
You may also find both eyes open works for you too........good luck, waiting to see the Pearl and Dean movie showing you on the range, from that might be able to help even further on whats going wrong for you
