Already has night sights with a TFO style front one. They are a little dim but still light up fine at night and that green fiber up front is great during the day.
I ended up going with a delta point for my G17. Like the fact that I didnt have to remove the optic to change battery. That and the triangular dot were the selling points for me. I like to be able to use the tip of the dot for more "precision"
