Hi, im new to this forum and after reading through the forums trying to answer my questions for myself.. i seem to have become information over loaded hehe.. im sure this question has been asked and asnwered before but just to double check? I own a Glock 23 .40S&W, I am a left handed shooter. When I shoot, I constantly go high and to the right. I shoot and shoot trying to get dead center. I cant figure out why I have this problem. Especially at the close range im firing it. I shoot the pistols at work (M9) just fine dead on everytime, but when I shoot my glock I cannot shoot as well. Do I need to adjust the sight? or what??? any ideas?? If I do need to adjust the sight how do i do this?
