So I grew up shooting rifles and always shooting with my non-dominant eye closed. Last year I started really getting into pistols. I carried over the practice of only using my dominant eye when taking aim. I realize that if I was in a self defense situation that this is not optimal. I tried openning both eyes at the range today and it was freaking blurry. 1. How do you shoot? 2. What was the best advice you got for shooting with both eyes open?
