Very high quality - Bianchi Accumold Nylon Double Mag Pouch

This pouch is very high quality. Mags fit very snugly. Almost too snug as they are a little difficult to draw under stress. I imagine they will loosen up with more use. I have mine set up in the horizontal position but it can be mounted vertically also. The pouch does not slide around on duty belts although if you put it on anything thinner than a duty belt or one of the ultrathin duty belts it will slide.
