Does any one know if they make or is there a way to get night sights for an FN five seven. I saw one at one point that had them but at the time thought nothing about them since I didn't have one yet. I now have one and have started carrying it most of the time. The only thing that I don't like is the lack of night sights. I was told you can send it in and have it done but I can't find anything about that so have no idea how to go about it.
