Absolutely loving the M&P 2.0!
The trigger really is that much better than the original. I do have the 9mm, the .40 and the .45 to compare it to, and I do have to say that it's absolutely all that it's cracked up to be.
The holster shown in the pictures was one that I pulled off the shipping table for the original M&P 4.25". I clicks in and there's no rattling around. So if you already have the original M&P and a holster for it, the new 2.0 will fit in just fine!
