I recently acquired the 4" version of the new M&P9 2.0 line, my sample does not have the TS. For those of you who own this pistol with TS, would you recommend that I add one? How does the placement and functionality of the TS on the M&P 2.0 compare to that of the TS on a 1911? Is it easy to manipulate, does your thumb rest nicely on top of it, as with a 1911?
Thanks!
