2011 complete magazines for wide-body double-stack race guns are stocked here in 9mm chamberings to fit USPSA Open and Limited division tube lengths. MBX, SVI, Grams, and Dawson Precision magazines cover the standard 126mm and extended 140mm tube lengths used by Open shooters chasing maximum capacity within the 26cm overall length rule, plus shorter Limited-legal options for shooters staying within division caps. Follower designs are tuned for reliable feeding of 9mm Major loads through comped Open guns, and base pad and spring combinations are selected to minimize reload lag while holding zero under recoil. Tube finishes and coatings resist the wear from high-round-count practice sessions and multi-day majors, and feed lip tolerances are held tight to prevent the double-feed and nosedive issues that plague loose aftermarket magazines. Whether you're running an Atlas, SVI, Staccato, or Infinity 2011, these magazines are sized to drop free from your magwell without modification. Build out a full case of match-day spares or replace a tired spring before your next club match. Fast same-day shipping on most orders at Shooters Connection.
