I decided to mess about based upon the info shared by a couple of our members above...and swapped out Tom's @Dark Star Gear PTD loop for a spare Tenicor DCC clip I had removed from my Velo 4 due to fitment issues with the two installed.
(Tom had mentioned to me that he was running his Orion with a G17 with just the one DCC clip, so I figured if the engineer approves it after training with the holster that way, why not?)
Here it is with a G17 magazine installed...which is only 1.25 oz more in weight than a fully loaded G19 mag.
The G19 mag is even stealthier but the 17 doesn't print. The Koala fits right into the inguinal crease making it very comfortable.
The hardware does not scratch or contact the magazine body at all.
