Don't forget you should be shooting broken wrist ie when holding out the pistol the wrist should be pointing down .you should not have to bring the wrist up to get the barrel level.Steyers have some adjusting screws in the base where the grip fits which when adjusted will bring the foresight up.
If you can adjust that so they do then file the grips to fit I've fitted mine so that the thumb just rests on the side and the fingers wrapping round support the gun ,gripping slightly just adds more control.
Hope this helps
