I've only had mine for a couple of months. It's seen two range sessions and one IDPA match and has right around 400 rounds through it. So far I'm really liking it.

My opinion is if you're in the market for a new polymer framed, striker fired pistol the M&P would be hard to beat for the price. If you already own an M&P I honestly wouldn't suggest you run out and upgrade to the 2.0. While the improvements to the 2.0 are nice, they are also fairly subtle. Well, except maybe for the grip texture. That one is pretty noticeable.
