IWB/AIWB mag pouch. Uses original clip. Allows carry of double stack 9mm magazines(tested with glock and HK P30/VP9 steel magazines) nose forward inside the waist band, or perhaps outside the waistband if you're left handed. Two different lengths allow ride height or mag size variation(glock 17 and glock 26, for example). Uses more common hardware(chicago screws for attaching clip, an M5 screw to adjust retention with the MRD).
The author remixed this model.
Mirrored/flipped body to accommodate rounds forward inside waist band carry. Adjusted hole geometry to use M5 screws for the MRD retention screw, M4 for the MRD attachment, and classic chicago screws found on Teklok/holsters to attach lip.
