KRISS USA Magazine Extension Kit for Glock 20 – 33-Round 10mm

The KRISS USA Magazine Extension Kit converts standard Glock 20 magazines to 33-round capacity, tripling your 10mm firepower without changing platforms. Purpose-built for shooters who need extended capacity for competition, range training, or backcountry defense against large predators, this kit maintains magazine reliability while significantly reducing reload frequency.

Constructed from impact-resistant polymer with a black finish matching Glock aesthetics, the extension installs without permanent modification to the host magazine. The kit includes the extension body, reinforced spring, and follower engineered specifically for the pressures and dimensions of 10mm Auto. Installation requires disassembly of the original magazine but does not require gunsmithing—basic mechanical aptitude and adherence to the included instructions are sufficient. Verify local and state laws regarding magazine capacity before purchase.
