A few days back I installed the aluminum FSS and trigger kit with the competition spring kit in my M&P9 and I really like how it turned out. I am thinking about polishing the trigger parts to see if it can become even smoother than what it is now. I have only 400 rounds through it with the new parts so I have not "broken" the parts in yet. But have anyone ever polished Apex trigger parts?
