Just got through installing and range testing a set of Dawson Precision sights for the wife's M&P9c. She went with the wide notch fixed, plain black, serrated rear and the green Fiber Optic .100" wide front. They were easy enough to install with a lined vise and nylon / brass drifts with the rear sight locking down with a set screw. The recommended front sight (.180" high) shot to perfect point of aim with PMC 115 gr ball at 15 yds, basically perfect for her intended purposes (IDPA toy). Her serious business guns are all older pre-lock S&W revolvers, 357s or 38 snubs
