I hear ya, Lefty26...
I am left eye dominant and have shot righty guns my whole life too. It never affected me one bit. Even in the Coast Guard, during bootcamp, I qualified on the M-16 by shooting lefty (believe me - they
tried making me shoot righty-- Not good... I failed... Even with a eyepatch, I still failed... [&o] So, they ended up putting some weird shroud thing on the ejection port for safety, and I shot lefty and easily qualified).
I had a left hand Remington 870 at one point, but traded it back in and got a common, righty 870. See, I found out that with a lefty 870, I couldn't do anything with it. I couldn't get accessories for it, like you normally can. Besides that,even though the safety was correct (lefty) on it,it would goof me up, because I'm used to righty safetys, even though I'm lefty. Go figure....
Long story short, there ain't nothing wrong with shooting righty guns lefty. My old Marlin 30-30 is righty - nobody even
MAKES a lefty lever gun anyway!
