The KRISS MagEx2 Kit is the ultimate capacity extending base plate for your factory standard Glock magazines, Gen 3 and later. The KRISS MagEx2 Kit is made up of the extended baseplate, outer sleeve, and extended spring, constructed of durable and lightweight reinforced composites. Combining the MagEx2 Kit with the factory standard Glock magazine body and follower is a perfect match of reliable feeding, toughness, and aesthetics for the KRISS Vector.

The MagEx2 Kit is caliber-specific and available in 9mm, 10mm, and .45ACP and designed for standard capacity G17, G20, and G21 magazines for an overall capacity of 40 rounds of 9mm, 33 rounds of 10mm, and 30 rounds of .45ACP for your KRISS Vector, Glock handgun, and your Glock magazine-compatible pistol caliber carbine.

Due to spring tension, hand-loading ammunition into extended capacity magazines becomes increasingly difficult the more you load. We highly recommend the use of a magazine loader such as the UpLULA.
