The KRISS USA 45 ACP Magazine Extension is a capacity-boosting upgrade for your KRISS Vector or Glock 21 platform. This three-pack of black extensions uses a proven modular system—pairing KRISS-engineered baseplates, outer sleeves, and extended springs with standard factory Glock magazine bodies and followers—to deliver reliable feeding and durability without compromising the gun's handling or aesthetics. Whether you're running a Vector or a Glock 21, these extensions add 17 rounds per magazine, bringing total capacity to 30 rounds of .45 ACP.
Built from reinforced composite materials, the MagEx2 system is lightweight and engineered to withstand the rigors of range work, tactical training, and defensive carry. The modular design means you keep your factory Glock magazines intact; the extension components simply upgrade them. Caliber-specific engineering ensures reliable springs and followers tuned to .45 ACP's ballistics and recoil characteristics.
If you shoot a KRISS Vector in .45 ACP or rely on a Glock 21, these extensions are a straightforward way to nearly double your magazine capacity without adding significant weight or bulk. Three packs give you flexibility—upgrade multiple magazines, keep backups loaded, or outfit a pair of guns.
