KRISS Mag-Ex2 Kit for Glock 17 9MM 40-Round

KRISS Mag-Ex2 Extension Kit

The KRISS Mag-Ex2 Kit is a capacity-extending solution designed to maximize your magazine potential. This kit transforms your factory-standard Glock 17 magazines into high-capacity 40-round magazines, giving you significantly more ammunition on hand without requiring entirely new magazines.

What's Included

The Mag-Ex2 Kit consists of three precision-engineered components:

• Extended baseplate — engineered for secure, reliable seating
• Outer sleeve — provides structural support and durability
• Extended spring — maintains consistent feeding pressure across the full 40-round capacity

All components are constructed from durable, lightweight reinforced composites that resist wear and maintain their integrity through thousands of rounds.

Compatibility & Performance

Designed specifically for Glock 17 Gen 3 and later magazines, the Mag-Ex2 Kit works seamlessly with:

• KRISS Vector submachine guns
• Standard Glock 17 handguns
• Glock magazine-compatible pistol caliber carbines

When combined with your factory Glock magazine body and follower, the Mag-Ex2 Kit delivers reliable feeding, proven toughness, and clean aesthetics. The kit maintains the same ergonomics and handling characteristics as standard magazines while nearly doubling your round count.

Why Choose Mag-Ex2

Instead of purchasing entirely new magazines, the Mag-Ex2 Kit extends the life and utility of magazines you may already own. The composite construction keeps weight minimal while providing the durability needed for serious shooting applications.
