Is that the "auto brightness level" model? If so, let us know how it works out... the brightness part, I mean : )I also bought the SCS MOS direct mount optic... Solar with rechargeable battery.built in and can use factory irons if needed.
I've just written S&W to let them know that the "loaded chamber window" (first pic) in the top of the slide/barrel hood on my new "optic-ready" M&P is not compatible with optics... it directs a jet of hot gasses and powder residue directly onto the optic lens, and already looks like it's causing a permanent mark on the lens after only 100 rds.!
Worst part is, you don't need that hole, since you can see if a round is in the chamber by looking in between the barrel and slide near the extractor (second pic).
