How important do you guys think these are? I'm waiting on my CHL license to come in so I've been looking around at a carry piece. I was leaning towards maybe the Kahr CW9 but it comes with a pinned front sight. I could have my local gun smith dovetail the slide to I could add night sights, but I'm sure that will probably void the factory warranty which I surely dont want to do since some people have had problems with theirs. The other option is to spend the extra $170 bucks and buy the P9 that already comes ready to add night sights. I originally was thinking they would be important to have, but the more I think about it, the more I'm not really too sure. What do you guys think? Cliffs: To night sight or not to night sight my ccw?
