Hello:
I have a fairly new M&P Pro Series CORE 9mm with the 4.25" barrel. It has started to occasionally fail to reset after firing a round. It happens with a variety of ammunition including factory and handloaded. It doesn't seem to matter if the loads are plus-P or competition softies.
I need to clarify: the sear is not resetting, resulting in a dead trigger and it must be cocked again to get it to fire.
Is this a known problem and how is it remedied?
