The KRISS USA MagEx2 Extension Kit in Flat Dark Earth gives your Glock 21 magazines a serious capacity boost. If you run a KRISS Vector, a Glock 21, or any magazine-compatible pistol caliber carbine in .45 ACP, this kit transforms a factory mag into a 30-round powerhouse—more ammunition between reloads without swapping platforms. The MagEx2 achieves this through a purpose-built extended base plate assembly and matching spring, both engineered from reinforced polymer composites that keep weight down while staying tough.
This is one of those parts that makes sense if you're serious about capacity but don't want to compromise reliability. The kit works with any standard Glock magazine body and follower from Gen 3 forward—so you're not buying whole new magazines, just upgrading what you've got. The Flat Dark Earth finish blends seamlessly with modern tactical setups, and the aesthetic consistency across your mag tubes matters when you're running a precision platform like the Vector.
Installation is straightforward: you're swapping the base plate and spring from your factory magazine with the extended versions from this kit. The result is a magazine that feeds just like your original but holds significantly more ammunition. For .45 ACP shooters, jumping from 13 rounds to 30 is the kind of practical upgrade that changes how you train and compete.
