It is not easy to find good light pouches. I am currently using a Basic Light Pouch from Custom Carry Concepts, which is unfortunately no longer made. Other options seem to be lacking.
I prefer my light pouches to be Kydex, since it seems to retain lights better than the leather pouches I have used. Minimizing the space required on a belt is helpful, and is where at least some of the others fall short in my opinion. Bezel-down carry places my hand in the most natural position to use the light with my thumb on the tail switch.
While I do not currently need a light pouch, at some point the pouches I have will certainly wear out, and I cannot be the only one who likes to carry a light on my belt in front of my magazines.
Tony, is there any chance of you designing a light pouch, perhaps along the lines of your current single magazine pouches?
I suggest starting with a design to accommodate a 1" diameter bezel, which will hold a Malkoff Bodyguard version 2 as well as the Klarus XT2C (not the XT2CR, which requires a special shape). Hopefully others will provide feedback about what they use, so that you can accommodate the more commonly used lights first.
