I agree with Pat, a lot of practice should get you there soon! The current wisdom is to go with your strong eye, however, most folks are pretty well dominant to their strong hand. I shoot bows left handed because I am, and had an early coach who was left handed. I have a dominant right eye, a bit late to change over, but I can shotgun either way, rifles I shoot right handed, because that was the way most rifles are set up and all my family shot right handed. I just learned this spring that archers are supposed to follow their strong eye. Pistol is easy, use left hand, aim with right eye! It is really just creating new muscle memory.
