MBX Extreme Defender/Duty 2011 DS 1911 9mm 20-Round Steel Magazines (Set of 3)
This is a set of three MBX Extreme Defender Series high-capacity magazines for 2011/1911 double-stack pistols. These magazines use MBX Defender tubes made from USA 410 stainless steel and are heat treated for durability, with MBX/Wolff-designed Defender series springs for consistent stacking and feeding.
Each magazine is configured for 9mm and 20-round capacity, with a tool-less billet aluminum base pad that uses a slide-pin retention system for quick disassembly and maintenance.
