I just got back my GP100 3" from CCG and I am very happy. I had them do the Ruger action job (which they also do the trigger polish), chamfer the cylinder/charge holes, and put an orange front sight insert in. I have not shot the gun yet, but the trigger pull is very smooth, and even throughout. The work they do isn't cheap, but its not too high either. I highly recommend them for revolver work, as they have done a very good job on every revolver I have sent them.
