Don't do anything funky with your eyes...if you're cross dominant (like I am) and the sights are aligned when you have both eyes open, or if one eye is closed, it doesn't matter....the bullet should hit point of aim.  Cross dominance is not some affliction that requires magic joojoo to correct.  I would suspect that the problem is in your trigger finger....this comes down to trigger control, and ensuring that your trigger finger is not moving the gun to the left when and before it breaks. It may help to rotate the strong hand around the grip, (on your guns with adjustable backstraps, you can enlarge/shrink the grips) to got the best placement of your trigger finger on the trigger. Center of the pad should be on the center of the trigger....pull directly to the rear.  Don't stop dry firing until it's habit....then learn to get this grip drawing from a holster.
