Tired of being able to shoot 33 rounds with your 9mm but not with your .45?
Now you can buy a capacity upgrade kit for your G21 mags from KRISS which will up your magazine round count to 30.
The upgrade kit is available for $35.95 – HERE
A pre assembled G21 mag and upgrade kit are available for $66.95 – HERE
G21 mags are around $20 most places now, so if your considering this you could save yourself some money by just buying the upgrade kit from KRISS and the mag elsewhere.
