I dont think there is an option for a pocket clip. Certainly AFAIK Streamlight dont offer one. I think you have two options, one is to rig up a clip yourself or get someone from CPF to make you one (if your lucky) or two buy a pouch with a sprung metal clip so you can use it without a belt.
Sorry but unless I'm mistaken you dont have that many choices.
