wow, i am 55 years old, and tonight discovered that i am left eye dominant. i have been shooting right handed since i could pick up and shoot my dad's bb pistol. maybe that explains why i have trouble keeping both eyes open when shooting. my uncle (my dad's brother) was this way also. but i think he was much worse. he actually broke his nose firing a 10 gauge shotgun one time. a quick shot at geese. every gun i own is right handed. and at this age, i really do not think i will be selling off all my collection and trying to learn to shoot left handed. but it will be worth some experimenting when shooting pistols.
