The KRISS MagEx2 is a capacity extension system built specifically for Glock Gen 3 and later standard-capacity magazines. This 9mm kit transforms a factory G17 17-round magazine into a 40-round magazine, adding 23 rounds of additional capacity without replacing your original magazine body or follower.
Each kit includes everything needed for installation: an extended baseplate, outer sleeve, and reinforced composite extended spring. The components are engineered from lightweight, durable composite materials that match the factory Glock finish and aesthetic. No tools are required for assembly, and the installation process is straightforward.
MagEx2 kits maintain the reliability of your factory Glock magazine while giving you significantly more ammo capacity. The system is specifically designed for standard-capacity G17 magazines (Gen 3 and newer) and works reliably in the KRISS Vector platform, Glock pistols, and other Glock-compatible PCC systems. The reinforced composite construction keeps weight gain minimal while maintaining durability through extended use. Built-in witness holes let you track round count at a glance.
Hand-loading becomes increasingly difficult as capacity increases, so a magazine loader is highly recommended. The kit is caliber-specific for 9mm and works exclusively with factory Glock OEM full-size magazines. Aftermarket magazines and compact or subcompact variants are not compatible.
No, the MagEx2 kit is designed exclusively for full-size factory standard-capacity Glock magazines like the G17. It is not compatible with compact, subcompact, or reduced-capacity 10-round magazines. You'll need a factory Glock G17 magazine (Gen 3 or newer) for this kit to function properly.
No tools are required. Installation involves removing the original magazine baseplate, inserting the new extended spring and outer sleeve components, and reattaching the extended baseplate. The entire process takes just a few minutes and can be done by hand.
The kit is designed for use with factory Glock magazines in the KRISS Vector platform and other Glock magazine-compatible firearms like pistol-caliber carbines. While the magazine will function in Glock pistols, the extension kits were engineered primarily for the Vector's performance and handling characteristics.
Extended-capacity magazines have increased spring tension, making hand-loading ammunition progressively more difficult the higher you fill the magazine. A manual magazine loader like the UpLULA significantly reduces hand fatigue and speeds up the loading process when you're working with a 40-round capacity.
