Hey guys need some help I am noticing that my support hand is pulling my front sight to the left it feels like my support arm is shorter than my on hand arm any suggestions on form to correct this? I also have another problem after shooting 4,5,or 6 rounds I notice my support hand slipping of my on hand some what due to recoil and it seeming like I am shorter on that side. Iam shooting a glock 34 and 17 Thanks
