Ameriglo i dot sights - AmeriGlo Smith Wesson Front and Rear Sets, No Shield, I Dot

These sights are a huge upgrade over the stock sights on my 40 cal M&P. The rear sight came off easily and the new one went on just as easy. The front sight came off with some persuasion. The new sight is a fitted part so be ready to do some shaping and filing to get it to fit. Be sure to file on just the sight and not on your slide. The goal it to be able to get it to slide in 1/3 of the way by hand and then tap it the rest of the way with a hammer and a brass punch. Everything I've read online says to remove it left to right or toward the ejection port side. I've also read that on the M&P guns it doesn't matter but I went left to right and it worked fine. Great product and great price from Optics Planet!
