Hello friends I'm super new to this so forgive me if i do something wrong. i recently purchased a M&P 15-22 Pistol. I have decided to get the double tap binary trigger witch functioned well the first mag. After I reloaded the second mag my pistol kept firing on the pull ejecting the round chambering the next round but fails to reset hammer on the release. So when I let go of the trigger and nothing happens. No click no strike. I started by replacing trigger & hammer pins with anti walk pins. No help at all. I cleaned and lubed up the thing and still the same problem. Any suggestions would be awesome. I'm at a loss Thanks
