I am right handed, and left eye dominant. I started this hobby about four years ago. When I bought my first rifle, I did some research on this as well. I was shooting long distance, so everything was through a magnified optic. From the beginning, I began to shoot with both eyes open. The right eye quickly and easily focussed on the target. Not squinting, helped to avoid fatigue, and helped with flinch. I have spoke with a few people who recommended covering my left eye, or even rotating my flip up lens cover to block my left eye. I found it more comfortable to just look down range with my left eye.
I purchased my first pistol a few months ago. I had to slow things down, to see where I would be more comfortable. I use my right eye to establish the sight picture. I just picked up my first AR, and use my right eye for both iron sights, and optics. Again, keeping both eyes open.
Two of my kids are left handed and left eye dominant. They shoot my guns, and really do not have too many problems. I think I would make some different decisions if I was to shoot as a lefty. A shotgun with bottom ejection, and a left side bolt action would be a must. The AR I just purchased now has full ambidextrous controls. The only gun that gives the boys a bit of grief, is the SR-22. It ejects the spent casings to the side and back a bit, so they have to just make sure they wear a shirt with a tight neck/collar.
