I experience the same type click when I got my MP 2.0 9mm compact. Tracked it down to the striker block spring. Not only could you hear it, you could feel it in the trigger pull.
I'd read that the plastic disc spring cover under the rear sight has a nub to capture the upper end of the spring on the newer models. It was speculated that the spring end being captured could be holding the spring off center with its hole and it's binding when compressed, whereas the older models have no nub to capture the spring. The spring end floats against, or finds its own center against the underside of the disc cover.
So I cut that nub off of mine. I also filled the center of the spring with grease to dampen it. Same principal as the foam piece in the center of the trigger return spring.
I also looked at the striker block hole with a magnifier, looking for tooling burrs at the top of the hole where it intersects with the striker bore, which there clearly was evidence of. After carefully smoothing those and the before mentioned spring work, the click is gone.
