I like night sites... and I like the front dot a different color than the rears...
So I went with Trijicon HD Night Sights w/ orange front dot...
As a result, when I put them on my new Shield I brought home the HI-VIZ® Fiber Optic Sights (Red rear, Green front) that came on the firearm. Changed at point of purchase, never used. Let me know if interested.
