The Sig Sauer Proforce 1911 14-Round Standard Base Plate CO2 Air Magazine is a factory replacement magazine designed specifically for the Sig Sauer Proforce 1911 series gas blowback airsoft pistols, including the Tacops, Emperor Scorpion, and We The People editions. Built with a heavy-duty metal alloy construction, this drop-free magazine replicates the weight and feel of a real firearm magazine to enhance training realism. It features a 14-round capacity for 6mm plastic airsoft BBs and houses a single 12-gram CO2 cartridge to power the pistol's high-pressure blowback system. This specific standard base plate version sits flush with the bottom of the grip for a clean, traditional profile.
