Just bought two new ones. M&P 40 & M&P 40C. I am a fan of the 9 and have an M&P 9. I've shot .40 out of both an XDS and a Sig and was not really a fan of the caliber. Recently had a chance to shoot the M&P 40 and liked the .40 out of the M&P platform. The Compact had enough grip while still being easily shootable and I can feed it the full sized mags if need be. Kind of a whole "pistol system" with the pair.
