I am getting a FN30 kit without the front and rear sights. Can you use a 1919a4 sight on the FN30? I have a source for the rear sight base and leaf can you use the 1919a4 rear site parts to complete it or should I just install a 1919a4 rear sight and bracket and be done with it? Or if anyone has a source for a complete rear and front site for the FN30
