I have both the full size (night stand) and shield (edc) 2.0 in 9mm. I sometimes forget to take off my shield when I get home, because it literally has become part of my wardrobe, kind of like my wallet. I would never be able to do that with my full size, it's just to heavy and bulky for me. I can't speak to the compact because I don't own it. But it does seem like the perfect compromise of both worlds. As for shooting, I love the M&P full size and it is accurate as hell. The shield, is just a little less so. And not quite as comfortable in my hand either.
Having said all that, I really don't get all the "it's so hard to shoot the smaller shield" talk. Am I as accurate with my shield as my FS?....not really. But we are literally splitting hairs here. I am still hitting center mass with my shield every time, and often times doing just as well with it. Probably the only thing that annoys me about shooting the shield at the range is I have to load the mags twice as many times.
If CC is your main focus right now, the shield is a great gun for that. No reason you can't learn to shoot properly with it and than move on to something bigger and better. And besides once you buy one...you will be hooked. It's only a matter of "when" you get the second one. Good luck
