Shoulder holster | Uncharted

I am currently attempting to replicate the shoulder holster used by Nathan Drake from the Uncharted-series for future cosplaying. I have however been unsuccesful in finding a similar one to replicate or any templates according to which i might construct my holster. I do not need an exactly similar holster, simply a roughly similar the one would do so that i can modify it later. Should anyone have templates or simply a rough outline of a shoulder holster similar to the one in the picture, I would be delighted to see one.

Cheers in advance.

Much obliged, the second to last one would appear to be documented with enough precision for me to make blueprints of them. I'll share them when they're ready.
