I learned something else about M&P the 9C model trigger. I have been fighting the 8 lb narrow folding trigger for a long time . Finally I bought an Apex polymer trigger and installed it. A big difference. Maybe not so much lighter but it is much easier to pull the trigger with the wider/thicker trigger. M&P needs to install the Apex in all of the narrow triggered models. The Shields are no problem just the M&P models with the small narrow trigger.
