For the M&P M1.0 version, you can buy a Reset Assist Mechanism (RAM), but only for specific models that have the internal locking system: https://www.youtube.com/watch?v=pmSf...Tl-d3baHfAZGSQ. This excludes .45, VTAC, and/or manual safety versions. For the M2.0, there is no internal locking system (that I've found). The Glock reset is renown for sure, and I love my Glock's, but the M&P ergonomics are (for me) far better. There is no perfect pistol out there .
I'm just after a trigger where I don't have to pretend that I felt the reset.
