I have had this pouch for a year now. I have used it a few different ways and some features and functions work better then others. its easy to move from gear and platforms. from the pack to the belt and back again. the SlickStick option is great for this
Retention is great with the different options suited to your need for carry. I use it on the Molle attachments on my range bag as well as a back pack on occasion to carry a multi tool and flashlight when hiking. I also do IDPA and when used in this fashion I leave off the bungee cord and carry the magazines in open top form. the elastic tension system holds the mags securely. my only complaint in this fashion is that occasionally when drawing the front magazine I have dislodged the second magazine. this is where I prefer a kydex mag holster in IDPA. but this pouch still works effectively enough.
Overall its a great Pouch for a Great Price and Versatility you don't see in any other product.
I've been carrying this pouch for about a year and am ready to replace it. Not because of quality, quite the contrary, the quality is fantastic. Top notch stitching, heavy duty materials, extremely durable. The problem is in the execution. The pouches are cut very high, which helps with retention, but hinders grasping magazines to draw them. I carry Glock 17 magazines, and without the three round extensions, I am unable to remove the mags quickly. This would be perfect if the pouch was cut about 1" lower.
I shoot IDPA and needed something simple but effective. I carry a G21 and this pouch is perfect for glock mags: not too bulky, great retention but still allows for quick retrieval/stowing. I've had rigid holsters before, and while this pouch may be less concealable, it more than makes up for that with accessibility and maneuverability.
