Looks like you are ordering from police ordinance as well. I ordered my G17 a while back, I hope to pick up this week. I decided to stick with factory sites for now. I can always add the night sight later on if I need them. plus for range shooting??? not really needed. Are you a LEO as well??
is your range dark during the days/times when you'd want to shoot or be allowed to shoot?
i wouldn't reject a gun that has them, but i wouldn't really spend the extra $150 or so to add them as an option.
a fiber optic, on the other hand - i'd certainly give that a go.
If it's too dark to see your sights, it's probably too dark to identify your target.
