I know I am in the minority but I have no problems or issues with the stock poly sights. I am not "active" anymore or not an operator. Been using the poly sights for 30yrs and I like them. I will admit that I have replaced a few the Glock steel sights. I tried Glock Night Sights, Meprolights and few others. I shoot better with the stock dot front and the outlined rear notch. For home defense I also use a Streamlight TLR-1HL. When using this light all I can see is the front and rear sight and they are completely black. The light toward the front just causes this with my eyes. One should use whatever works the best for him.
