I just recently bought and installed the Apex DCAEK and RAM in my M&P9. While the DCAEK made the trigger better, I feel that the RAM had very little effect on the reset. It might be a little more audible, and be a little easier to feel, but I don't feel it made the difference that I have heard others talk about.
For those of you who have installed them, what are your opinions on the RAM and DCAEK?
