The KRISS USA MagEx2 Extension Kit for Glock 21 Magazine upgrades your factory .45 ACP magazine with extended capacity and purpose-built reliability. Designed specifically for Glock Gen 3 and later platforms, this extension kit pairs with your standard Glock 21 magazine body and follower to deliver 30 rounds of .45 ACP — a significant boost for competition, home defense, or extended range sessions. Whether you're running a KRISS Vector, a modern Glock handgun, or a Glock-compatible pistol-caliber carbine, the MagEx2 transforms baseline capacity into serious firepower without sacrificing feed reliability or ergonomics.
The kit consists of a reinforced polymer extended baseplate outer sleeve and a matching extended spring — lightweight composite construction that keeps mag weight manageable while handling the demands of higher round counts. Alpine White finish gives your magazines a clean, distinctive look that coordinates with modern tactical gear. Note that the Alpine finish on the MagEx2 kit differs from the Cerakote finish on the KRISS Vector itself, so expect a distinct aesthetic if you're matching them as a system.
Installation is straightforward: the extension kit works with your existing Glock 21 magazine components, so there's no need to replace your current mags or source hard-to-find replacements. Caliber-specific design ensures proper feeding and function — this kit is engineered for .45 ACP, not 9mm or 10mm. If you're building a Glock 21-based setup or stacking capacity for serious training and competition, the MagEx2 Extension Kit is a proven way to get more rounds downrange from proven platform.
