I am getting light primer strikes with my M&P 9mm Pro 5 inch barrel.
As in FTF. (failure to fire)
I have the APEX Tactial sear and USB.
I had the RAM, but took it out since the sear failed to reset caused FTF. Removal of the RAM seemed to stop the sear failing to reset.
I have the stock striker spring but a competition trigger return spring. All other springs are stock. The pistol has about 4000 rounds through it.
Does anyone have any suggestions on how to cure this? Or something to check?
