I really like the concava style pen. I'm wondering what has happened to the clips for the concava pen kits. Within the past few years they have added hardware onto the clips for adjustment. I have not been able to get them to a tight fitting they way they are currently designed by PSI. The last kit I made, the clip was so tight that it would not move. Is there another source to purchase concava kits? Is it possible to make a concava style pen from another style kit (such as slim line)? Thanks for any comments.
