Dan's Directions
I just finished doing the "trigger job" on my M&P40c.
I followed Dan Burwell's PDF directions and pictures with the exception that I did not remove any material from the rear hump of the sear, just polished it.
I am ecstatic with the results.
I have given all of my autos a "Fluff and Buff" but this was my first foray into more in depth mod.
