I just purchased the new Shield Plus and also purchased separate night sights. When I asked my FFL who is supposedly is a gunsmith about installation he claimed the front sight is difficult to remove and to install and my gun will get scratched. Is this true? I certainly won't let him do it and will try and find another gunsmith who is better qualified, but I have never heard that this is a difficult process. I have read many reviews of night sights with people installing them themselves on Shields.
