I like the Tritium Pro Handgun Night Sights from TruGlo. They're very sturdy and bright with the lights out. The problem is that they don't fit right. I ordered a set for a Glock 17 Low to co-witness through an RMR footprint red-dot on an RMR cut slide. At 25 yard they shoot 4 inches too low. At 10 yards it was obviously worse. A shorter front sight would fix this. I tried contacting TruGlo with no reply. Overall, I'm not real happy.
