Finally broke down and ordered the Carry/Duty kit for the M&P9, should be here and maybe installed in time for Thanksgiving break. In theory it'll lighten it up a little and smooth everything out. I've heard all sorts of good things about them, so I've got decent hopes.
I guess I should break down and get my hands on a trigger pull gauge if I want to do a good review of it... anybody know who's got them cheap?
