The Aker Leather 523 D.M.S.™ Twin™ open top double magazine pouch is was the original dual carry combo pouch on the market. Constructed from the highest grade of vegetable tanned leather, the D.M.S.™ Twin™ features 1 solid brass tension screw so the wearer can adjust the security or speed of draw. It fits two spare magazines from Colt single stack .45 magazines to Smith & Wesson M&P 9mm or .40 caliber magazines. As with all D.M.S.™ accessories, the Twin™ comes standard with our custom injection molded quick on/quick off Air-Flo™ paddle unit. It features specially designed air holes that provide additional breathability during wear, especially on long rides or hot days. Twin barbs hook underneath the belt and grab your waistband to keep the pouch in place while you draw your magazines. However, it is also convenient to unhook and remove the pouch, placing it on your desk or in a drawer. The paddle unit is attached with two screws and washers, which can be unscrewed to remove the paddle. On the back of the pouch is a molded leather belt slot, if you prefer to use that method of carry. We recommend replacing the screws and washer so it does not snag on your clothes. Many federal agencies use this combo pouch for their detectives though it is also a great addition to your EDC equipment!
