I'm cross eye dominant. Meaning, right hand dominant but left eye dominant. This video helped me a ton. I've heard a red dot on pistol helps, but I've not gone that route yet.
I've been right handed, left-eye dominant my entire life. It seems natural to me. Both eyes open is the only way to shoot, or bowl, or drive, or baking cookies, or anything else you need to see for. Right eyed macular degeneration makes it easy to see a blurry sight picture on a clear target.
