I just bought a P2D. It came with a holster that has both a belt loop and a plastic "D" ring that obviously hooks on to something. It is an annoyance when the belt loop is used. Before I cut it off and trim the webbing back and melt it I am curious as to the purpose of the ring. Anyone know? I also bought a twofish velcro holder for my bike and it works well. I was looking for a new bike light and decided to get a good flashlight and use it for a carry light and for the bike.
