I really hated the low quality pistol pockets built into my safe door panel and wanted a more dynamic system for a while. When I found out about Grey Man Tactical and researched my options, I realized it was exactly what I needed. Hope the photos speak for themselves which are fresh off my DIY work including buckle setup and sewing. Note: based on all measurements, I bought the 10.25x19 with intention of removing bottom 2" for my 3rd gen GoRuck Bullet 15.
Perfect fit for my vertx gamut 2.0, keeps everything in place but still easy to get to.
