Does APEX make a reset assist (RAM) for the M&P (I have a -9c) WITH the thumb safety? Extensive searching has turned up 0 results.

No. There is no RAM for safety equipped M&Ps.

No RAM. However if your M&P is older you can change the trigger housing or whatever it's called to the newer version with a notch on it to give a more pronounced reset.
