I have a set of trijicon on my Ruger P345. I ordered them from Ruger so they are a direct factory replacement. If I understand correctly about what Novak sights are, I'd go that way if I was planning on concealed carrying the gun in some type of holster. I love the trijicon sights. They aren't quite as easy to see in daylight as a plain white dot but they are fine for me. You get three white circles instead. Turn the lights out and there is nothing better.
