So many people don't carry a spare magazine for one simple reason "IT'S SO DANG UNCOMFORTABLE". Well SwapRig Holsters has solved that problem. The XtraMag Pocket Magazine Carrier is the most comfortable way to carry a spare magazine that is totally concealed without a cover garment. Even better than that the XtraMag is also a simplified loading system for your quick, efficient reload. No need to fumble for the magazine that you dropped in your pocket or that "digging into your side" belt mag carrier we have all tried to make work.
