I guess I'm old school, but I will be installing some 10-8 Glock sights with the brass bead insert on a used G17 I picked up last week. I like the ledge on the back sight that I can rack the slide with one hand on my belt if needed. The brass bead is easy to pick up and works well for me. I had this set up on a 1911 and I liked it. You can get it with a night front sight if you wish.
Here is what the 1911 sights looked like before I installed them.
