I have recently bought a 19 with fixed sights that will have to be replaced. I shoot IDPA and I have shot with Glock Adjustables and Meprolight night sights. I am looking for good set up just for competitive shooting. I am leaning toward an all black adjustable rear with some sort of red dot front. I haven't found this combination yet. If anyone can offer any suggestions or lead me in the right direction I would be most thankful.
