FIST vertical shoulder rig. This company offers another "factory custom" approach to holster production. I had one of these for the Glock 27, which is a fairly small gun. With the offside angled double mag pouch, I felt like I was carrying a ham under each arm, the rig was so bulky. The design concept is a good one, but the execution is lacking. The leather is dry, (feels like "splits"), and quality was poor as compared to others. In addition, the owner (Jim Murnack) was quite rude and insulting to deal with. (FWIW, in response to a query about FIST holsters on a gun-related bulletin board, I related my experience and opinions, then Mr. Murnack signed on and took umbrage. I emailed him personally, and received some poorly-written, sometimes-incomprehensible insults in return. As it turned out, he had mistaken me for a different person posting to the same thread, and he later apologised, but nonetheless demonstrated a poor attitude for a businessman, in my opinion. He DID take the rig back and refund my original cost, after the smoke cleared, though, and I give him credit for that. It's the only shoulder rig I've ever returned to the maker, and I did so only because he seemed to want to make things right.)
