Kriss Glock 21 Factory 30rd .45 Magazines – Set of TWO!
KRISS MagEx2 Glock 21 30-Round .45 ACP Magazines — Set of Two
So you want real extended capacity for your KRISS Vector or Glock 21, not a flimsy aftermarket guess. This set gets you there. Two KRISS MagEx2 30-round magazines in .45 ACP. Each one is a factory Glock 21 magazine combined with the KRISS extension sleeve and a heavier-duty spring. Built for the KRISS Vector and double-stack .45 ACP Glocks.
This isn’t a knockoff magazine with a plastic sleeve slapped on. First, the base is a genuine OEM Glock magazine, not a third-party copy. Next, the KRISS extension adds steel-reinforced polymer construction matching the durability of factory Glock mags. Finally, the spring is longer and heavier-duty than stock, designed to handle the added tension of feeding 30 rounds reliably.
Will these Kriss Glock 21 Factory 30rd .45 Magazines – Set of TWO!fit my Glock?
Yes, across most double-stack .45 ACP Glock models. So these magazines fit the Glock 21, 21SF, 30, 30s, and 41. Also, they work in the KRISS Vector and any pistol caliber carbine that accepts Glock .45 ACP magazines. However, these will NOT fit the Glock 36, which is a single-stack .45. Therefore, confirm your exact Glock model before ordering.
Will these work in my PCC or carbine?
Kriss Glock 21 Factory 30rd .45 Magazines – Set of TWO! Yes, across a wide range of platforms. So any pistol caliber carbine that accepts Glock .45 ACP magazines will run these. Also, confirmed compatible platforms include the Ruger LC Carbine, CMMG Banshee, CMMG Resolute, TNW Aero Survival Rifle, Just Right Carbines Takedown, and many others. Therefore, this magazine works across a broad ecosystem, not just the KRISS Vector itself.
Is loading 30 rounds of .45 difficult?
The last few rounds take real effort. So KRISS specifically recommends using a magazine loader like the UpLULA for the final rounds. Also, the spring is intentionally heavier-duty than stock to ensure reliable feeding, which means more resistance when topping off. Therefore, a quality magazine loader is a smart companion purchase if you plan to run these regularly.
Are there states where I can’t order these?
Kriss Glock 21 Factory 30rd .45 Magazines – Set of TWO! Yes — several. So these 30-round magazines are restricted in California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Massachusetts, Maryland, New Jersey, New York, Oregon, Rhode Island, Vermont, Washington, and Washington D.C. Therefore, verify your state and local laws before ordering, since purchasing or possessing high-capacity magazines can be a serious legal issue in restricted states.
What makes this Kriss Glock 21 Factory 30rd .45 Magazines – Set of TWO! better than a standard 13-round Glock 21 magazine?
Kriss Glock 21 Factory 30rd .45 Magazines – Set of TWO! Pure capacity. So a factory Glock 21 magazine holds 13 rounds. These magazines more than double that, reaching 30 rounds before a reload. Also, numbered witness holes on the back let you quickly check remaining ammo at a glance without dropping the magazine. Therefore, for range sessions, training drills, or KRISS Vector builds, the capacity difference is immediately practical.
