I'm a big fan on the m&p shield 9mm as well, but I carry a pf9. Very small, and I actually want the heavy trigger and long pull. It'd be diffent if it was a target pistol, but its not. Most of the time its a pocket carry,I want to reduce the chance of it going off as much as possible, but i dont want a safety. Never know what could happen if you fall, get in a car accident, or get hit by something. Gotta figure, should the time arise that I would actually need it (and i certainly hope I never will), the last thing I'm going to be thinking about is proper trigger pull, its more than likely going to be pull the pistol and yank the trigger.
Still wanting something different though. For the time being, the pf9 still serves its purpose.
