KRISS MagEx2 40-Round Extended Magazine (9mm)

The KRISS MagEx2 is a factory extension kit that turns a standard full-size Glock magazine into a high-capacity stick for the KRISS Vector. The 9mm version is assembled on a Glock 17 magazine and brings total capacity to 40 rounds, which suits the Vector's role as a recoil-flat blaster where long strings of fire are the point.

Because the MagEx2 is caliber-specific and built on the host Glock magazine, it tracks the Vector's caliber compatibility exactly: 9mm Vectors run the 40-round 9mm kit on a G17 mag, 10mm Vectors take the 33-round kit on a G20 mag, and .45 ACP Vectors use the 30-round kit on a G21 mag. The kit ships fully assembled, so there is no need to source a donor magazine or fit the extension body yourself.

The MagEx2 also functions in any Glock pistol or Glock-magazine-pattern PCC that can run an extended stick, but its length makes it a range-and-defense magazine rather than a concealment option. For baseline capacity in the Vector, the factory 17-round Glock 17 magazine ships in the box; the MagEx2 is the upgrade for shooters who want fewer reloads.
