KRISS MagEx2 Kit G17 9mm +23rd Alpine White

Description

The KRISS MagEx2 Kit takes your standard Glock G17 9mm magazine from 17 rounds to a full 40-round capacity with a simple conversion that doesn't modify your original magazine body. This isn't a complicated upgrade—it's a straightforward baseplate system using durable reinforced polymer composites paired with a redesigned spring that handles the extended capacity without sacrificing reliability.

What's in the MagEx2 Kit

You're getting three core components: an extended baseplate, an outer sleeve, and an extended spring. These work together to house the extra 23 rounds while maintaining that factory Glock magazine feel. The whole package weighs just about 4.8 ounces, so you're not dragging around extra weight on your belt or rifle. Assembly is straightforward—you disassemble your factory mag and swap in the new components. Everything is designed to work with genuine Glock Gen 3 and later G17 magazines, not aftermarket copies.

Built for the KRISS Vector and Beyond

KRISS engineered the MagEx2 specifically for the Vector platform, but it works equally well with standard Glock pistols, PCCs (pistol-caliber carbines), and any system that runs Glock G17 mags. The Alpine White finish gives it a modern look that coordinates well with lighter-colored platforms. Keep in mind that due to increased spring tension when fully loaded, a magazine loader is worth having on hand—hand-loading 40 rounds gets progressively harder the fuller you get.

Important to Know

This kit only includes the extension components; you supply your own factory Glock G17 magazine. It won't work with aftermarket magazines or compact/subcompact models. The polymer construction keeps everything lightweight while delivering the durability you'd expect from a purpose-built design.
