My MP .40 LE trade in 1.0 has Trjicon night sights on it. There is an M&P logo in the center of the rear sight. I have searched the interweb to no end looking for these night sights. Why can't I find them? My MP was manufactured 11/2015, so I'm guessing they are less than 2 years old? I even checked the S&W website. They're not there either. Anyone know where I can find them? Yes, I know there are other night sights out there, but I WANT these!
