In the world of firearms, precision and reliability are paramount. The KRISS MagEx2 Kit embodies these principles by offering an unmatched capacity extension for your standard Glock magazines from Gen 3 onwards. Tailored specifically for the discerning shooter who demands excellence in every aspect, this kit is a testament to thoughtful engineering and purposeful design.

At its core, the KRISS MagEx2 Kit comprises an extended baseplate, outer sleeve, and extended spring—all meticulously crafted from durable yet lightweight reinforced composites. This construction ensures that while you gain additional rounds, you do not sacrifice ease of handling or overall firearm balance.

Designed with caliber specificity in mind, this kit accommodates 9mm, 10mm, and .45ACP ammunition with remarkable efficiency. When paired with your factory-standard Glock magazine body and follower—whether it's for a G17 in 9mm achieving a formidable capacity of 40 rounds; a G20 in 10mm holding up to 33 rounds; or a G21 chambered in .45ACP reaching up to 30 rounds—the result is seamless performance marked by reliable feeding mechanisms and robust durability.

Not only does it enhance functionality for your KRISS Vector but also extends compatibility across Glock handguns and any pistol-caliber carbine accepting Glock magazines. This makes it an indispensable addition to any serious shooter's arsenal seeking both versatility and increased firepower without compromising on aesthetics or dependability.
