Frequently Asked Questions

Will the KRISS Mag-Ex2 fit my standard Glock pistol?

The Mag-Ex2 is designed primarily for use with the KRISS Vector and other Glock-magazine-compatible pistol caliber carbines. While it is built around a factory Glock 9mm magazine and will physically feed from compatible Glock-pattern pistols, KRISS USA notes that this product is not manufactured, authorized, endorsed, or warranted by GLOCK, and GLOCK does not represent compatibility with their pistols. For best results and reliability, use the Mag-Ex2 with the KRISS Vector or a dedicated PCC platform.

Why does this magazine have a 40-round body but only hold 10 rounds?

The Mag-Ex2 ships in a California-compliant configuration, meaning the magazine body retains the full-size 40-round profile for ergonomics and aesthetics, but is blocked to a maximum of 10 rounds to comply with California's magazine capacity restrictions. This gives shooters the look, feel, and grip advantage of a full-length magazine while remaining fully legal for sale and possession in California.

Does the Mag-Ex2 come with a magazine, or do I need to supply my own Glock mag?

This listing is for the fully assembled Mag-Ex2 kit, which includes a factory-standard Glock 9mm magazine already installed in the extension body. You do not need to purchase a separate Glock magazine — everything is ready to use right out of the box.

    Fits in any firearm that accept Glock Mags

    Great alternative to having the aesthetics of a larger capacity magazine, but still staying California compliant allowing only 10 rounds to physically fit in it. It definitely made my AR15 pistol aesthetically more pleasing than the ugly California compliant tiny magazine. Very pleased with this product would definitely recommend and order again without hesitation.
