The fist one I pressed in without doing anything. The cap went in twisted and the long end of the clip dug in and damaged the finish on my pen. I pressed it back out, and used the screw to fully remove the clip and inserted it again. Then I reattached the clip after the cap was installed. Now it feels like there's not any tension for the clip to hold onto your pocket.There is an adjustment screw that sets the tension, have you tried loosening it.
