Description
The Kriss Mag-Ex2 is a fully assembled extended magazine that pairs a Glock factory magazine with Kriss's proprietary extension system to deliver serious capacity for 10mm platforms. You get 33 rounds ready to go with no assembly needed, making this a practical choice whether you're running a Kriss Vector, a Glock 20, or any Glock-compatible pistol caliber carbine in 10mm.
What Makes the Mag-Ex2 Work
Kriss took the proven reliability of factory Glock magazines and added an extended baseplate, outer sleeve, and reinforced polymer spring to increase capacity from 15 rounds to 33. The polymer construction keeps things lightweight while maintaining the durability you need for hard use. Steel reinforcement inserts inside the Glock magazine body and an impact-resistant follower handle feeding consistently shot after shot.
Mag-Ex2 Design and Compatibility
This magazine is engineered specifically to match the aesthetics and function of the Kriss Vector platform. It fits Glock 20, Glock 29, and Glock 40 handguns, plus any pistol caliber carbine that runs Glock magazines. Numbered witness holes on the back let you see at a glance how many rounds remain loaded. The black polymer finish integrates seamlessly with modern tactical setups.
One thing worth knowing: hand-loading the higher capacity can get challenging due to spring tension. A magazine loader is recommended if you plan to load these frequently. The extended length is noticeable compared to factory magazines, but the geometry stays compatible with standard Glock ergonomics for most holster and platform setups.

Frequently Asked Questions
Will the Mag-Ex2 fit my Glock 20 or other Glock 10mm models?
Yes, the Mag-Ex2 is designed to work with the Glock 20, Glock 29, and Glock 40. Since it's built on a factory Glock magazine, it's fully compatible with any firearm that accepts standard Glock 10mm magazines, including pistol caliber carbines and the Kriss Vector platform.
Is this magazine assembled and ready to use right out of the box?
Absolutely. This comes fully assembled with no additional work needed. You can load it and go straight to the range or field. The extension system is already integrated with a factory Glock magazine body.
What's the best way to load 33 rounds into this extended magazine?
Due to the high spring tension in extended magazines, hand-loading all 33 rounds can be tiring and tough on your thumbs. Most people find a magazine loader like the UpLULA worth the investment if they plan to load these frequently. It makes the process much faster and easier.
Can I use the Mag-Ex2 in a .40 S&W firearm?
No. This magazine is specifically designed for 10mm and should not be used in .40 S&W firearms. Kriss does not recommend cross-caliber use, as it can cause feeding or functional issues.
