While 100% kydex pouches work well for belt rigs and competition stuff, they work less well for integrating into a chest rig, war belt or in my case, a plate carrier. Existing nylon offerings all generally need some kind of retention flap or elastic, which slows reloads. And, the mouth of the magazine pouch generally collapses in, which slows inserting a partially spent magazine during a tactical reload.
Previously, I've been running HSGI's very popular TACO magazine pouches, which use elastic around the edges for retention, which eliminates the need for any kind of top flap. They are fast for speed reloads, but still suffer the problem of collapsing inwards, which makes reinserting a partially spent magazine an often fiddly thing.
The Esstac KYWI line of magazine pouches is what I've gone too--first with rifle magazine pouches, and now finally to pistol mag pouches. The "KYWI" stands for kydex wedge insert--these are hybrid nylon/kydex sheaths, with a nylon exterior and a kydex interior. The kydex interior holds the magazines securely, yet releases quickly during a reload. The mouth of the pouch stays wide open, making reinserting magazines about as consistent and hassle free as you're going to get. As far as I'm concerned, these are the best option for use on a MOLLE rig.

If you're frustrated by your current pistol pouches, looking for an upgrade or looking to set something up for the first time, these are the way to go. Esstac makes 'em in single, double, triple and quad pouch formats. Mine came from SKD Tactical.
