.45 ACP 2011 magazines built for Limited Major and Single Stack cross-platform use are stocked here from MBX, sized to the wide-body 2011 frame for shooters running .45-caliber loads for maximum power factor. These magazines carry the capacity advantage of the double-stack 2011 platform while feeding the larger .45 ACP case reliably through comped and non-comped Limited guns, with follower and feed lip designs tuned specifically for the cartridge's dimensions rather than adapted from 9mm or .40-caliber tooling. Tube lengths meet USPSA Limited division capacity limits while keeping the magazine footprint manageable for fast reloads, and spring rates are calibrated for the heavier bullet weights and slower velocities typical of .45 ACP Major loads. Shooters running a wide-body 2011 chambered in .45 for Limited or looking to bridge Single Stack ammunition inventory into a double-stack platform will find these magazines built to spec rather than repurposed from another caliber. Base pad and floorplate hardware round out the package for quick, positive reloads on the clock. Fast same-day shipping on most orders at Shooters Connection.
