Dial In Your M2.0 Flatty
With the new Flat-Faced Forward Set Trigger Kit you can dial in the trigger pull weight to the range you prefer. Using different combinations of the Apex and factory sear and trigger return springs you can set your trigger pull in the M2.0 from approximately 6.37 lbs down to 4.38 lbs. This range is based on our test sample so your results may vary, especially taking into account differences in factory tolerances.

I know this may be subjective, but can you specify which configuration(s) will provide more of a "wall" feel? I've heard from some reviews that some configurations can remove the feeling of a wall altogether and makes the trigger feel like one continuous pull.
I've got my M&P at the 4.38 lb. setting and I love it, but I wouldn't mind a bit more of a "wall".
Thanks.
With Smith using their latest -10 deg striker, they've eliminated quite a bit of the wall. You could try an Original M&P(silver in color) striker that lacks the 10deg marking, that should help.
