So I noticed this immediately when my Tritium Fiber Opic (TFO) sights came in. The front sight is elongated towards the rear sight, the purpose is to allow light into the front sight's FO tube. It subtracts from the sight radius of my G27 which bothers me. What are your thoughts on the TFO and subcompacts? Do you feel the sight radius difference is negligible? What do you use on your subcompacts?
