KRISS MagEx2 Kit for Glock 20 – +18 Round Capacity 3-Pack

The KRISS MagEx2 Kit extends factory Glock 20 magazines by 18 rounds, converting standard 10mm mags into higher-capacity options for extended range sessions or duty use. Each kit includes a base plate extension, spring upgrade, and follower to reliably feed the additional cartridges. This three-pack provides enough components to convert three Glock 20 magazines.

Constructed from durable polymer with corrosion-resistant internal components, the MagEx2 requires no permanent modification to factory magazines. Installation involves disassembling the magazine, replacing the factory spring and follower with the upgraded components, and attaching the extension base plate. Basic mechanical aptitude and familiarity with magazine disassembly is recommended. Magazine body remains factory Glock; only internal components and base plate are replaced.
