I have a brand new set of Trijicon tritium (yellow front dot) Night sights. (SA137Y is Model #). These will fit the traditional M&P’s/2.0s, but will NOT fit the optics cut versions. I made the mistake of buying these and they won’t fit the optics models. They are not able to be returned but I paid a decent amount for them. I am selling them for $50. Still in box. Never mounted. ..I am in Philly burbs area. Text 267-645-9755 if interested. I have a few pics.
