Watch this video from Direct Action Gear showing their Speed Reload Pouches for Rifles, Pistols, and SMGs... "RIFLE: Open top rifle magazine pouch, designed for speed reloads but with secure magazine carry at the same time. The special internal material, combined with a limited-size top opening and tension-adjusting elastic cord, prevents the magazine from falling out if it gets snagged.

PISTOL & SMG: Just like our rifle pouch, our Pistol pouch is designed for speed reloads but with secure magazine carry at the same time. The special internal material, combined with tension-adjusting elastic cord, prevents the magazine from falling out if it gets snagged."
