Glock pistol question?

If it was a matter of your shot groups being tght, all in the same area and consistant,theyou would look at the gun. Since they arent, then look at the shooter. i am not trying to say anything nasty, I just think that you might want to work on your fundementals. If your groups are not tight, practice on a good body position, sight alignment and your grip. Seriously, I dont even use my sights at 25 to 30 feet. I use a modified Weaver and am a point and shooter. But I believe that at that distance, you should shout as you would in a real life situation. Pull, point, aquire shoot. But, do a little research on a good hooting posture.... Could be your off hand. Try a cup and saucer with your off hand elbow down and tight to your body,your gun hand almost locked, thumbs pointing at target and your body turned at an angle from the target. If if your off center, get those groups tighter first.
