thanks Deth Lives, but no.
those are leather. the type i saw were made of nylon or some other synthetic material. the holster itself was rectangular and included a pouch for one additional magazine. the straps were also nylon with the same securing format as the leather one; one strap over the left shoulder and one strap that wraps across the chest, under the right arm then across the back connecting to the shoulder strap (just like the M7 design).
are there any former Marines here with time in the sandbox?
think M7, just nylon.
