Hello Mas, Early on when I first started shooting Glocks I had problems with my shots shooting left. Through the range sessions over the years I seem to have corrected this problem but I don't know what I did to fix it. I hear of it often and see people do it from time to time when I'm at the range. Is there a reason that this issue seems to come up more with Glocks than other pistols? Also, do you have any advice for those that are experiencing this problem about how to correct it? Thanks!
