An update: I spoke with David at CGW, told him the issue I was having. He said that my issue was one he sees in about 1 in 200 guns, and was a timing issue. Basically it was what it looked like, there wasn't enough stroke of the trigger bar to release the sear. He told me the two available solutions were to change the hammer, or remove some of the polymer behind the trigger. I will eventually get the hammer, but for now the polymer removal does the trick. I will also replace the roller, man that thing is funky... It really allows some side to side slop. Hopefully this will be helpful to next "1 in 200".
