Update: Loving the Kyle Defoor sights on my G19, and the MGW sight-pusher is a must-have if you install sights on Glocks. I love it. Free to my friends, $5-10 if I don't know you. I'm going to re-coup the cost and a lot of people will get a great deal.
Here is how they look, photo taken from normal distance of eyes-to-sights:
Very rapid to pick up with the gap between the FS and the notch, and very precise when needed. I love them.
