Frank, I'm going from memory here, but I think cross-dominant issues were discussed in "Gun Digest Book of Combat Handgunnery," 6th edition. I also did a column on the topic 2 or 3 years ago in GUNS magazine, might be available in the archives at www.gunsmagazine.com
Short form: for one-handed shooting with the right hand and left eye, rotate the gun 15-45 degrees toward the left eye and the sights should come dead into line with the pupil of the left eye. This can work in a two handed stance as well, or try the following for two-hand shooting:
With classic Weaver stance (both elbows bent) drop the right side of your head toward your right shoulder. This should align left eye reasonably well with right hand.
With the Ray Chapman modified Weaver stance (gun arm locked, support arm bent), firing with your right hand and aiming with left eye will be facilitated by keeping the head erect and bringing your chin to your right shoulder/bicep area.
With the Isosceles stance (chest square to target and both arms locked out forward) the handgun will come center with your head and a slight, natural adjustment will allow a dominant eye on either side to align quickly.
Give it a try and let us know here how it works.
