Decided to have a little fun with my M&P 40. I started by milling the rear of the slide to mount a buris fast fire 3 and then added some cooling slots in the front, followed by a bead blast finish. That melonite is tough to get off. Installed an apex aluminum forward set trigger and Ram. A storm lake ported barrel and mag well from speed shooter specialties were also installed. Just need to take it to the range now.
