I used an MGW M&P Sight Tool to install the rear TFO just to see if it would work. I was surprised at how well it fit the SD9 and the rear sight went on with almost no effort. The MGW tool does not appear to work with the front sight, so 5-6 taps with a plastic hammer and punch and the the sight was in. About as easy of sight installation as I have ever done (and I have a lot). The TFO's are visible at night but shine brightly in the sunlight. The sight picture is clean and they are fast on target. I normally go for a plain black rear and tritium dot front, but since I had these already I am going to stick with them.
