KRISS USA MagEx2 Kit for Glock 20 – +18 Round Extension, 3-Pack

The KRISS MagEx2 Kit extends standard Glock 20 magazines by 18 rounds, converting 15-round factory mags into 33-round extended magazines. Designed for shooters who need higher capacity without sacrificing reliability, this kit is popular for range work, competition, and backcountry applications where 10mm firepower matters. Each extension maintains the magazine's feed geometry to preserve function with factory and aftermarket ammunition.

Machined from reinforced polymer with a matte black finish, the MagEx2 installs without permanent modification to your existing magazines. Installation requires disassembly of the factory magazine baseplate and spring, replacement with the included MagEx2 extension tube and spring, then reassembly—basic gunsmithing skills and proper magazine disassembly tools are recommended. This 3-pack includes everything needed to convert three magazines: extension bodies, springs, and baseplates.
