KRISS Super V 25 kit quickly converts your Glock 21 magazine to hold 25-rounds. Easy to install, no tools required. Fits G21 and G21SF magazines.
Note: First generation NFML G21 magazines (circa 1995 and older), will have occasional functional issues that can cause the follower/spring assembly to hang up as the magazine unloads. Best results will come from using the newer generation G21 magazines.
