I have a M&P 5" Pro and the dang trigger stopped re-setting during a match. Smith and Wesson has been completely un-responsive to my issue. They told me to clean the striker channel, which I did and trigger will only reset about 1 in 5 pulls. Still waiting for the return authorization. I am trading the gun to a fellow IDPA competitor but I want it fixed before I trade. We have 2 other M&P's and have not had this issue. Any suggestions to fixing the problem before I start raising a fuss with S&W? Thanks.
