This is probably going to sound like a stupid question, but bear in mind that what little handgun marksmanship training I ever had was over 40 years ago, it was with a Model 1911 Colt, and we were taught to stand perpendicular to the the target, grip the pistol with the right hand, only, and sight with the right eye. Here's my question. I have determined that I am "left-eyed", even though I'm right-handed. What would be the best grip and stance for me to use, should I sight with my left eye, or should I attempt to keep both eyes open? Any advice would be appreciated.
