You are spot on - sent several Private messeages to your request.

Iused open tru glo sites for years until my eyesight got so bad from age I could not see the back ramp - why I went to a scope.
The Tro-glo sights I used allowed for windage and elevation on the back ramp. You would be amazed how far to the right I had to adjust to center my shot.
