I LOVE the feel of the full-size M&P, and can't stand the M&P Compact. Amazed that a slightly short grip changes it for me so much.
The SR9c, on the other hand, is extremely comfortable for me.
Quality is there in both, but I prefer the lack of safeties on the M&P.
Hard choice if they both fit you well.
