Kriss USA Mag-Ex2 9mm 40-Rd Extended Magazine for Glock 17/Vector

The Kriss USA Mag-Ex2 is a factory 9mm Luger extended pistol magazine built around a standard Glock 17 pattern body and engineered to bring total capacity to 40 rounds. Designed primarily for the Kriss Vector family of pistol-caliber carbines and pistols, it also drops into any standard Glock 17-pattern pistol or pistol-caliber carbine that accepts a G17 magazine, giving Vector owners a high-capacity option and G17 shooters a long-range, training, or competition-ready upgrade.

The Mag-Ex2 pairs a polymer magazine body, finished in matte black, with an extended base plate outer sleeve and a longer, heavy-duty spring to reliably feed the full 40-round count of 9mm Luger ammunition. The extended base plate is dimensioned to leave roughly half an inch of additional clearance at the bottom of a Glock 17 grip, so the magazine seats and feeds correctly without bottoming out the magazine well.

The Mag-Ex2 ships as a fully assembled unit and is ready to drop into a Kriss Vector or any compatible Glock 17-pattern firearm straight out of the box. Whether you run a Vector CRB, SDP, or SBR for the range, training, or home defense, the Mag-Ex2 delivers the extra round count that has made the Vector platform so popular, all in a factory-engineered Kriss USA package.
