The Aker Leather 616 Carry Comp II double magazine pouch is the most comfortable and durable dual mag case on the market. Constructed from the highest grade of vegetable tanned leather, the Carry Comp II features two solid brass tension screws so the wearer can adjust the security and speed of draw. It fits two double stack 9mm or .40 caliber magazines, such as for the Glock 17 or Smith & Wesson M&P 9 or 40. The two belt loops on the rear of the case are spaced to set the 616 on either side of your pants belt loop, so it does not move around your waist. It is designed to accommodate belts up to 1-3/4" and close with secure solid brass one-way snaps.
