Mine has Truglo Fiber Optic sights (not the tritium variety -- gun will never be used at night). I spent $49 at Amazon for them. They fit perfectly and are a damn sight (I had to say that) better than the originals. My other guns have Trijicons on them. They work perfectly. In bright daylight, the SD's sights are better than the $160 trijicons in my opinion. Of course, the fiber optics would be useless at night. Excuse the iPad camera, please.
