Glad you like the Metal. I have several friends that shoot it and love it as well. I personally didn't think it was worth the extra $$ over the polymer MP 2.0 that I have.
Also if you do not like the trigger, Check out Overwatch Precision, they make an awesome trigger for the Metal.
Side note.... I know the girl in your avatar and can get you another cool picture of her holding an M&P if you want
