This pen looks great. Good job. I made a couple of the power click pens from PSI but was disappointed in the quality of the pens. No matter what I did I could not keep them from rattling. I asked a couple of other people and they said it was just the nature of a click mechanism. The click mechanism is loose in the top. Does the Sierra have the same rattle when finished? I had a customer that really liked the power pen but when he rattled it he put it back in the case.
