I have been getting a slight felt and audible click while pulling the trigger. It was happening with the safety on or off. After much examination and head scratching I realized what the problem was. The disconnector had chewed a small indent into the bottom of the slide (in the cut in part). When I pulled the trigger it would click as it moved over the indent before the sear moved. I polished the indent out and smoothed the top of the disconnector. It feels great now. My question is why did it create the indent to begin with and will it come back? I only have 10,000 or so rounds through it so I don't think it's a standard wear problem. I assumed the top of the disconnector was a little to sharp but I could be wrong. Let me know what you guys think.
