C.o.r.e. sights - Meprolight Self Illuminated Tru-Dot Fixed Night Sights For Smith & Wesson M&P C.O.R.E

I would neither recommend nor purchase meprolight sights agin based on these sights. The rear sight was so loose that it could be pushed into the dovetail with no resistance. In fact, it was so loose that until the set screw was tighten they simply fell out of the dovetail. Additionally, after installing and tightening the set screw, the recoil worked them loose and they fell of mid shot.
The one positive attribute they have is they are very bright.
