I use the universal holster from Niteize. It fits my TK41 just fine and rotates as well. It's got a very firm hold of my light and I have no fear of it falling out of it.
The Ripoff BL-150 holster works nicely. Also the HWC Police security nylon universal holster is a tight fit but works well after being stretched a little. I didn't find the maxpedition holster adequate. [h=1][/h]
