Anyone have any suggestions for a pocket clip?

Greetings. I picked up a Surefire 6p incan from a clearing out sale on boyscouts of america's website + 20 percent off.

Does anyone know of a decent pocket clip for this light? I tried my solarforce, but it would require me to use a solarforce tailcap too, to prevent the pocket clip from sliding around. Which would kind of defeat this light.

Thanks!

Add an O-ring between the clip and tail cap is what some people do I think.
