After firing my M&P 9mm ,I always wanted a set of sights I could zero, especially now that your favorite load may be hard to find. Dawson Precision in Florence Tx. has made a selection of adjustable sights for the M&Ps. I ordered the Target Model with black serrated front and rear sights. These give me a sharper and clearer sight picture. As a result my 50ft. groups fired from a horizontal rest for my forearms shrank from 2.25 to 2.50 inches ,down to 1.75 inches . Here is the target and what the install looks like. When you recieve your set, included is a set of 2 drift punches [aluminum ] so you won't mark your finish and instructions on how to do it yourself if so . If not ,go to your gunsmith , as the factory set on your gun are pretty tight in the dovetail. Dave Dawson lists several options such as fiber optic ,white dots and etc.
