Description
The KRISS MAGEX2 Extension Kit is a straightforward way to squeeze more capacity out of your factory 10mm Glock magazine. Built for Glock 20 and G40 mags, it takes a standard 15-round magazine up to 33 rounds by replacing the floorplate with an extended baseplate, outer sleeve, and longer spring. Everything is made from tough, lightweight reinforced composite, so you get the extra rounds without a bunch of added heft. The Flat Dark Earth finish also gives it a clean, matched look next to a KRISS Vector or a Glock in an earth-tone setup.
What the MAGEX2 Kit Actually Does
This is a kit, not a complete magazine, which is worth knowing before you order. You supply the factory Glock G20 or G40 magazine body and follower, and the MAGEX2 hardware handles the capacity boost. It's designed around genuine Glock full-size, standard-capacity mags of the correct model, so it plays nicest with real Glock parts rather than aftermarket bodies. The result is reliable feeding with a look that fits right in on a Vector.
Where the FDE Extension Kit Earns Its Keep
More rounds per magazine means fewer reloads at the range, in competition, or during a long training day. If you run a KRISS Vector, a Glock 20 or G40, or a Glock-mag-compatible pistol caliber carbine in 10mm, this kit stretches your time between mag changes and keeps you shooting. It's a favorite among Vector owners for exactly that reason.
A Quick Tip on Loading
Heads up on the extended spring: as you get deeper into the stack, the spring tension makes topping off by hand tougher toward the last several rounds. A magazine loader like an UpLULA makes the job painless and saves your thumbs. It's a small add-on that pairs perfectly with any high-capacity setup like this one.

Frequently Asked Questions
Does the KRISS MAGEX2 Extension Kit come with a magazine?
No, this is a kit only and does not include the magazine body or follower. You provide a factory Glock G20 or G40 standard-capacity magazine, and the kit supplies the extended baseplate, outer sleeve, and spring. Combined, it brings your magazine up to 33 rounds of 10mm.
What magazines does the MAGEX2 10mm kit fit?
It's designed for factory Glock full-size, standard-capacity G20 and G40 magazines, Gen 3 and later. KRISS does not guarantee fit or function with aftermarket mag bodies or the wrong model. It's also not compatible with reduced-capacity 10-round, compact, or subcompact magazines.
Will this MAGEX2 kit work with my KRISS Vector?
Yes, this is exactly what the MAGEX2 line was built for. It works with the KRISS Vector, Glock 20 and G40 handguns, and Glock-magazine-compatible pistol caliber carbines in 10mm. The Flat Dark Earth finish also lines up nicely with earth-tone Vector setups.
Is it hard to load a full 33 rounds by hand?
The extended spring gets stiffer as you approach the top of the stack, so the last several rounds take some effort by hand. A magazine loader such as an UpLULA makes loading quick and easy. It's a worthwhile companion for any high-capacity magazine like this one.
