Streamlight Protac 2L: Clip popped off, how to replace it?

I've had a Protac 2L for about a year and a half, and rarely carried it because the clip simply snapped onto the body with no real attachment point. I gave it another chance...Now the clip is gone forever on a rifle range somewhere, I have no way to keep the light clipped to anything and it just falls down to the bottom of my pocket. No word back from customer service at Streamlight, looks like I'm on my own here. Are there any third-party parts that I can use on this light to try and make it usable again?
