I used to be neither. Primarily right handed. I had Lasik and am left eye dominant now. Kinda sucks. I still shoot fine but it is little bit of a change. Both eyes open vs 1 eye closed, whatever works best for ya.. I can shoot any weapon left handed just fine. Buddy is a lefty so been there done that. But I can do most things well enough as lefty so not sure if Im helping. I think the learning is the hardest part at first. My daughter was rgt hand left eye and she just couldnt get it right.
