The MagEx2 is KRISS USA's magazine extension kit for the Vector's 9mm magazines, taking the standard GLOCK-pattern stick and substantially increasing its capacity for range and competition use. The kit includes the extended body, a longer spring and a follower — everything needed to convert a magazine you already own.

This one comes in the Alpine finish. Fewer reloads is the obvious appeal, particularly on a pistol-caliber carbine where recoil is negligible and the limiting factor at a match is almost always how often you have to stop and change magazines. Installation is straightforward and requires no permanent modification.
