i know old thread - but i think i have been doing one since i was on a rifle shooting team when a kid.
now i want to do both eyes open for handgun target etc. it was hard - i was all over the place yesterday at range.
i think i am right hand - left eye dominant. so i can ignore the other gun image and focus on front site - but what about the target. i swear i was seeing two targets and was getting my aim so off - frustrating - i think i just need to practice dry fire at home.
