Supposedly they're changing all the M&Ps to have a positive reset like on the Shield, but even the recently shipped ones that I've seen have still had the old trigger.
That's unfortunate. I haven't picked up a M&P in a while, but if they are changing the stock trigger system, I might have to pick one up.
Maybe it's just me, but I like the audible click of a trigger reset. It helps eliminate uncertainty.
