Kriss USA Mag-Ex2 Extension Kit 45 ACP 30-Rd Polymer Black - Compatible w/ Glock 21 Gen3-5

The Kriss USA Mag-Ex2 Extension Kit is a magazine extension designed to boost the capacity of your factory Glock 21 45 ACP magazines. This Mag-Ex Kit 2 takes a standard 13-round Glock 21 magazine and extends it to an overall capacity of 30 rounds, giving you a serious boost in firepower without giving up the reliability of a factory Glock magazine body.

Constructed from durable black polymer, the extension is purpose-built for use with Glock 21 Gen 3-5 13-round magazines and is fully compatible with the KRISS Vector pistol caliber platform, Glock handguns, and any firearm that accepts Glock-pattern magazines. Whether you are running a KRISS Vector, a Glock 21 pistol, or another magazine-compatible host, this kit transforms a standard factory mag into a high-capacity option ready for range sessions or defensive use.

The Mag-Ex2 is the simplest way to add capacity to your existing Glock 21 magazines - no need to buy a separate extended magazine. Install the extension onto your factory 13-round Glock 21 magazine and you are ready to go.
