Holsters for the Horn Hunter Full Curl System

Does anyone have any suggestions on a type or style of thigh holster that works with the horn hunter full curl system? I ran into to many bears this year so I bought a XDM 45 4.5 I have never packed before but from what I can tell the thigh holster is about the best and only way to go when packing a full sized pack and binos on my chest. I am thinking about the black hawk special operations thigh holster but not sure if it hangs down low enough.

A tactical thigh holster would work independent of your Full Curl. Most just loop onto your belt and are low profile so the waist belt of the pack would simply sit over it. The firearm is low enough that it should not interfere with the pack at all.

I'm leaning that way. I'm pretty sure that the special operations holster isn't low enough especially if the pockets on the pack are full.
