Combo: 5x Alpha-XiP Pouch
Easy to put on your rig. Easy to adjust even when on the range in a match. Fits all types of double-stack mags with the 3 sets of adjustment inserts that comes with the pouch. Everything I wanted on a mag pouch, DAA has thought and through and delivered, with good design and build quality. I have always preferred high-quality polymer over aluminum, because they are simply stronger and tougher, and cost a bit less.
I would venture to say that this is THE BEST mag pouch I have tried so far, and I have tried many (Black Scorpion. G/R, Ghost and cheap ones from Amazon).
