I think you will like the M&P C . Bought one soon as they came out, wanted to try a modern design and don't think much of Glocks. Ran it for 6 months or so then decied to switch my IDPA shooting over to the 9L when it came out. Keep the C as a back up gun, in case the 9L goes down in a match, and for IDPA Back Up Gun matches. I see more and more of them in matches. Carolina Cup without an actual count there seemed to be as many M&P's as Glocks shooting Stock Service Pistol.
Real impressed with the design it's clearly an update on the Sigma which was a try to duplicate the Glock. Egronomics are as good as you will find. Like anything new they have had a few problems, nothing major and S&W turned mine with extractor problems around in less than a week at no cost.
I still don't know exactly how switching out the Recoil spring for one with less power effects the striker spring but it does and gives less than reliable ignition. I down load 9mm's to the mimimum power factor for match shooting . Went back to the factory spring boosting my loads a bit and works fine now. Can't blame that on S&W. Glock gets around this by not recominding handloads. One reason they are reliable , the guy behind the grip can't screw up the ammo.
