This is a quite uncommon left handed P7 PSP holster that is for IWB carry. This is a Mitchell Leatherworks holster.
From what I understand Mitchell Leatherworks is the company that came before Mitch Rosen. If you look at the Mitch Rosen website there is a holster similar to this one called the ARG (American Rear Guard or Ayoob Rear Guard) and this holster in fact is stamped "ARG P7" right by the Mitchell Leatherworks logo stamp.
This holster is black.
Asking Price of $85 I can take PayPal for no fee.
