I have them on mine and I like them a lot. I don't really care about the "night" part though. The width of the front blade and the size of the rear notch are perfect. I can get a very fast sight picture.
i have them, my only complaint, and i'm is s fla, is that in bright aylight you don't see the spots well. in subdued or low light they are great, with the bright dot over the subdued dot. i'm considering using model or nail paint to enhance the sights, without covering the tritium), to enhance them in bright daylight. they are designed to be non reflective and do allow a quick target acquisition. the final decision rests with the user.
