I've been going clipless with sticky pocket holsters of various brands and they all work great for Appendix carry. Not having a clip allows you to adjust the positioning to facilitate concealment or comfort, such as when seated or driving.

The Black Pearl got a Remora and I carried all day today while driving and walking about with prospective customers, sometimes over rough terrain, and it was completely comfortable and undetected. It never slipped from it's Appendix carry position.
