Then, the drill is to move left, using the cover. Now, the light shines hard, but my target, as soon as it gets dark, will be invisible to me. I swap position, using my left fist to hold the light and bracing against the pistol, my fist under my right thumb. Immediately, I start missing, consistently right of target. I relax and quit pushing so hard with my left fist, concentrate on using the light and pressing the trigger, and my shots come back towards center.
