I have several of the much superior Preon (Foursevens/Prometheus) after market Clips available if you want one to pimp out this massdrop copper or the Ti (lumintop tool) light let me know. $10 USD shipped.
see a photo here of what it looks like on the light, awesome;
Made from heat treated stainless steel, all clips are designed to deliver: reliable, durable, good retention, smooth pocket engagement, and not damaging to your clothing. Clips can also be re-tensioned if they get slightly bent out of shape.
My OEM clip broke after a week so I bought this one and its great looking, functional and perfectly fitting.
