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

The KRISS MagEx2 Kit extends factory Glock 20 magazine capacity by 18 rounds, providing substantially increased firepower for range use, competition, or field applications where 10mm capacity matters. This kit converts standard G20 magazines into extended-capacity magazines through a precision-engineered base plate and spring system that maintains reliable feeding.

Each kit includes the components needed to convert three factory Glock 20 magazines. Installation requires disassembly of the original magazine—straightforward for users familiar with Glock magazine maintenance, though care must be taken during spring installation to ensure proper tension and feeding geometry. The MagEx2 system uses KRISS's proprietary magazine extension design engineered specifically for the Glock 20's 10mm Auto cartridge dimensions and feed angle.
