I am left eye dominant and predominantly right handed
I can shoot pistols in either hand equally well, and I shoot left handed rifles better than right, BUT I shoot all semis right handed usually, I just close my left eye
I had to go to a left hadned Bow though for that sport.
I shoot the semis right handed because well, most were designed that way, mag changes, shooting techniques, even ejection can play a part, I know the brass will not hit me shooting an AR left handed, but there is always that little bit of a twinge, and that can affect my accuracy...
so... shoot right handed if you can handle it, close your left eye, and good luck
