Tried it once on a M&P full size 40, and didn't care for it. The slide is not milled. I had to remove rear sight, and use an adapter plate. If it were milled out getting the optic lower I'd try it again. I don't really want or need another pistol though. I've seen where others have drilled the white dot out of their front sight, then recessed the top out for fiber optic rod. I did this on my shield 9mm the other day, and blacked out rear dots. Gives me a good sight picture as long as there's a little light. Those s&w front sights are really in there. Brass punch won't budge them.
