So, if said person has to drft rear sight, left/right of center, to accomplish that, thats just the way that it has to be. Like i said, all of my handguns have the rear sight just right of center for my POA/POI to be the same. Now someone else, might shoot one of my guns, and be off target, If thats what someone needs to be do to be on target, do it.
