Kriss MagEx2 Kit for Glock 21 +17 Rounds, 3-Pack

Kriss MagEx2 Magazine Extension Kit

The MagEx2 Kit represents a practical solution for shooters seeking increased magazine capacity without sacrificing reliability. This extension system transforms your standard Glock 21 magazine from 13 rounds to 30 rounds—a substantial increase for defensive, competitive, or training applications.

What's Included

Each kit contains three complete extension systems, giving you multiple magazines to work with:

• Extended composite baseplate
• Outer sleeve
• Extended spring
• Compatible with Glock Gen 3 and later magazines

Design and Construction

Kriss engineered the MagEx2 using reinforced composite materials that balance durability with lightweight performance. The system maintains the proven reliability of factory Glock magazines while adding capacity. The extended spring ensures consistent feeding throughout the magazine's full range.

Compatibility

This kit is specifically designed for the Glock 21 (.45 ACP). It works seamlessly with:

• Glock 21 handguns
• Kriss Vector carbines
• Any firearm accepting standard Glock 21 magazines

Performance

The combination of the factory magazine body and follower with the MagEx2 extension maintains the feeding reliability Glock users expect. Whether you're training, competing, or preparing for home defense, this capacity increase provides a practical advantage without compromising function.
