I just recently purchased a cz rami 9mm, very happy. But my question is has anybody changed their sights on there rami. The sights on it now are night sights with are great, but I have a hard time see my sights because of my age. I would like to know if anybody has changed their sights and to what kind. Some of the places I've contacted do not offer sights for this model. Wou,d appreciate feedback.
