slimmest profile flashlight holster

hello all,
can anyone recommend or suggest me the slimmest holster available. im currently using a niteize holster which i love, but now i need something not as bulky. the nite ize uses a clip to attach to your belt which causes the whole holster to stick out quite a bit.

the size of my light is roughly a c8 but with a smaller head/bezel. its a thrunite tn11s.
