Trigger pull issues related to criminal/civil liability concerns seem to come down more to pull weight vis-a-vis factory spec for duty guns, than anything else.
Call S&W Customer Service toll-free at 1-800-331-0852. Ask for the DUTY TRIGGER spec for pull weight on the M&P. Compare that with the pull weight specified by Apex on whichever of their options interests you. If it's within S&W weight spec, and doesn't have a telekinetic reset or anything, I for one wouldn't worry about it.
Another option would be to order the Pro model, with S&W's own Performance Center-designed M&P trigger enhancement, which as I recall does give a nicer pull but is still within the factory approved duty pull weight range.
