It all arrived today. Holster and mag carrier.
Initial review:
Mag carrier - Awesome. Holds the magazine tight to the body. Nothing to compare it to except my Fobus one I use for IPSC.
Holster- Uncomfortable. But I've never carried AIWB so I need to play with it. Not blaming that on the holster. FWIW I'm 5'11" and 170 lbs...
