I bought my shield 1.0 with stock night sights. They're made by trijicon and have the lip that allows one handed manipulation on the rear sight. I also have a 2.0 full size which i changed the sights out to hiviz f.o. and they had the lip. I now switched to trijicon bright and tough thinking they were the same type as stock (green tritium and white ring) but they do not have the lip on the rear sight. I see the HD's do though on closer inspection but i do not want the colored front ring. Are the shield sights HD with a white ring or were they just always made that way? Are they bright and tough?
