Anyone that does it for the M&P should but may cost more, Ive wanted to mill a RDS on mine and get predator cuts but Im waiting for a threaded barrel first
If you really want to mod out the SD, Apex Tactical has lots of fun things to do with this firearm. You can contact them for barrel mods, slide mods, etc. They also have the trigger and duty carry kit for it. Contact them and ask, you may find that the mods will out cost the firearm.
