Thank you all for your advice, i attached a pic of my 15 to 20 yard group, all while aiming for the center. I shoot 40's nothing else. I kinda felt like at times it was hard to stay focus on my sight picture and i'm almost always never able to track my shot after trigger pull. I have incorporated dry firing, the wall drill and balancing with a spent round at the front of the sights trying to improve a slow clean trigger pull with out muzzle interruption. I have never thought to try ear plugs, might give it a try. Please give me any feedback on the attached picture. 3 guns used, 6 bullets a piece.
