Universal Double Magazine Pouch, OWB 9mm .40 Double Stack Mag Holder Dual Stack Adjustable Retention Pistol Mags Holster Fits Glock/Sig/S&W/Beretta/CZ/H&K/Colt/Browning/Taurus/Springfield/Ruger/CANIK

Good retention, easy to adjust retention on draw for user preference. Compact size of holder doesn't overcrowd space on your belt; minimal appearance and concealable if you do your part. Good choice when carrying an spare magazine, which you should always do, as your primary magazine may malfunction thus you need to carry a spare magazine.

Holds your double stacks very good. Adjustable tension to your liking. They seem very durable and clamp on well. We will see how they hold up, Happy with my purchase.

Perfect for duty built, easy to install and remove. Adjustable for different magazines.

The belt clip is sturdy enough, but bulky. The standoff is considerable, making this holder virtually unconcealable, and uncomfortable while sitting. The size of the mag pockets makes it useful for a variety of double stack mags, but only marginally so, as tightening the adjustment to provide retention for smaller magazines leaves the pockets out of square and in minimal contact with the mag body. It's worth it to bend the retention tabs in the sides and back of the mag pockets to suit your retention preference. Not a hard job, just heat the tab up with a lighter and bend it in a little, as you see fit. Double stack 45 magazines are hard to fit, but, it's meant for 9mm, .357 Sig, .40 S&W.Bottom line- I had to toss this holder in the oven and reshape the mag pockets to the double stack .45 mags I intended to carry with it, which is a pain. A custom kydex carrier may be better for you if you don't have one of the magazine patterns listed in the item description. All in all, it was a hassle, but I made it do something it wasn't intended to do. That being said, if you like the look of it and don't need concealability; or if you just like to fit your own gear and don't mind tinkering: get one. The price is right.

I bought this for my son for his first USPSA match! Very impressed! It fit the Glock 19 mags with no issues. Really like the belt adjustability, cant and the quick release option. For sure will be picking up another one for his belt!

They were very sturdy, easy to use, easy to set up, as well as tighten to my magazines

Holds both my canik mags nice and snug. Durable and comfortable

Works well but my P226 mags are small and fall out no matter how tight you tighten the holder. To be fair, larger Glock magazines will probably work just fine. The holder you want is made by Cytac available on Amazon.
