I Have a new Glock 19 Gen 4 and I am interested in purchasing the Crimson Tracer laser for it. I have seen a couple of videos on You Tube showing how to adjust windage and elevation. Since I am a newbie, I am not a very good shot with this pistol. I am still learning on how much finger pad to place on the trigger to shoot straight. I realize too little finger pad can sometimes cause the pistol to shoot to the left of center. Here is my question: how can I sight in this laser when I cannot consistently hit the target? It seems to me I would need to place the pistol in some type of holder similar to a vice like sighting in a rifle? I know this is not how you do it of course. Do I need to get someone who can shoot this pistol straight in a consist tight group? Thanks.
