I really like the TT universal mag pouch because it is one of the most flexible/adaptable mag pouches I've used. I first bought u-pouches to use on a heavy rig, where I wanted the ability to load up a couple of extra mags if needed, but I also wanted to be able and use the mag pouches for other purposes. The universal mag pouch has served these roles for me on my TT chest rig. Platforms currently running these Universal Mag Pouches: Tactical Tailor (TT) Mini-MAV, TT, one piece MAV, and TT 2 piece MAV (this is my standard rig and I have 3 universal pouches on it, standard load out is 2 mags per, but an option to step-up one per. 1. Mag pouch, 1-3 USGI steel w/mag pullers or Magpul G1, G2 with mag pullers. Pouch flap pulls down tightly. Tighten up the shock cord to reduce profile when running 1-2 mags. 2. Trauma kit: I use this pouch for the TT medical insert on a mini-MAV that I built as a low viz SPR rig. Tactical Tailor says the med insert is for the 5.56 pouch and it does work in that pouch, it just works BETTER in the universal pouch. 3. Smaller multi-purpose pouch. Protein bars, water bottles, box of ammo, cold beer, whaaa I mean water, GPS/Kestrel/map holder 4. sidearm holster. Fits a G17 or 19 perfectly. 5. Backup radio pouch (PRC-148/152). Batteries, tools. etc. So if you build a rig and flexibility and adaptability factor into your loadout, this is a great pouch. In fact, since my first rig running these u-pouches, I haven't ran standard 5.56 doubles again. Took em off and put in my spare locker and replaced them with universal pouches. As I said, if I need to boost my standard combat load by one mag per pouch I can. If I need to convert one pouch to support some other mission, additional trauma kit,suppressor, eaaddition firearm. It really is that flexible. t Don't let the "fight light" fool you, this pouch is tough & comes with MALICE clips, and a lining that makes mag inserts & pulls nice and smooths. I highly recommend this pouc
