KRISS MagEx2 Kit for Glock 17 – +23RD 9mm Extension

The KRISS MagEx2 Kit for Glock 17 converts factory 17-round magazines into extended 40-round capacity without requiring a new magazine body. This system uses a patent-pending coupling mechanism that stacks two magazines vertically, adding 23 rounds of additional 9mm capacity. It's designed for range use, competition, or situations where extended capacity provides a tactical advantage without the bulk of drum magazines.

The MagEx2 Kit includes the coupling housing, base plate, and spring system needed to link two Glock 17 magazines. Installation is straightforward—no permanent modifications to your magazines are required, and the system disassembles for cleaning or return to standard configuration. Constructed from reinforced polymer with steel internals, the kit maintains reliable feeding while keeping weight manageable. Note: This kit requires two Glock 17 magazines (not included) to function.
