I have a 40 Shield and same problem. How could I shoot all other guns, including my 44 mag and be that off to left? Read the banner advertisement it should help. My problem was not locking my elbows. As simple as that. After 500 rounds to the left, locked elbows today and now dead on. Boy that made me happy. Trigger will get better, grittiness and pull after a few hundred rounds. Hope this helps. Give it a try.
