I asked and currently blue is the only color, next production run there is supposed to be more than one color. The clip is all metal, not plastic. Looking at it the little key ring between the light and the clip would most likely let go first, but that would take quite a bit of force.

Looking at the Streamlight site the clip looks to be very similar. It's a little hard to tell what size the clip is, but the clip is the same size as the one on a Streamlight Nano. Managed to pick up one of those too at the show.
