To answer a couple of the Q's posted:
1.) No it is not the pouch from chinookmed.com (good site though). Check out tacmedsolutions.com for this particular pouch. It come ready for drop leg applications. Just unclipping a couple of straps makes it mountable to your kit.
2.) I've never used the HS Gear rig in question. It seems like it would get the job done as well as the TACMED Solutions' rig.
3.)OPTACTICAL is a must know site for any gear head
like myself. You guys should definately pick up the tacmed gear line.
I can email pics of it the way I have it set up if you guys want them.
