Resurrected 2010 thread.
I'll play, though.
The SR9c has the improved trigger (as compared to the first run of the SR9), which I love.
As for the M&P having worked its way into the LEO arena, I have been told that Smith & Wesson aggressively pursued this. I am told that they offered extremely aggressive buy/exchange programs, to help LE agencies transition to the M&P.
