I used the investigator for over a year with no o-rings and is was a little rough after extended writing. I added orings to the pen, 10 on all groves plus one on the ends of each cap thread. It's way more comfortable now, I regret not making the move sooner. The pen also stays clipped in my pocket better now as well. There was a few close calls where I almost lost it and just happened to see it laying on the ground.
