This thread is ridiculous, if he wants one he wants one. Nothing more needs to be said. All you have to do is get a sear housing with a mag disconnect safety and install it in your gun. It's a very easy process to make the swap and it will work just fine. Let me dig around in my armorers kit, I might have a housing with a mag disconnect in there as I have taken a few out of guns from people who did not want them and installed a few into guns for people who did.

ETA: I have one for a M&P 1.0. Cannot advise if it will work in a 2.0 or not.
