Capacity matters when it comes to defensive preparedness. Whether you’re optimizing a patrol carbine or adapting a personal handgun for extended drills, a reliable and lightweight magazine extension can make a real difference in reload tempo and overall readiness.
KRISS USA MAG-EX2 delivers a purpose-built capacity extension by combining an extended baseplate outer sleeve with an extended spring crafted from reinforced composite materials. Shop this product
What the KRISS USA MAG-EX2 is and why it matters
The KRISS USA MAG-EX2 is an extended capacity base plate kit engineered to work with factory standard Glock magazines. It consists of two primary components: an extended baseplate outer sleeve and an extended spring. Both parts are constructed from durable, lightweight reinforced composites designed to preserve reliable feeding while adding rounds to your existing magazine stack. Priced at $23.39, this is an affordable way to increase on-gun capacity without buying entirely new magazines.
Key features at a glance
– Extended baseplate outer sleeve: Adds body length and ergonomic purchase for faster reloads and improved control when manipulating loaded magazines.
– Extended spring: Maintains consistent feeding pressure across the increased stack height while matching the factory follower and magazine body.
– Reinforced composite construction: Reduces weight compared to metal alternatives while offering impact resistance and long-term durability.
– Factory Glock magazine compatibility: Designed to pair with your stock Glock 17 magazine body and follower, enabling a reliable match of feeding geometry and aesthetics.
– Application flexibility: Appropriate for use in the KRISS Vector Glock 17 handgun and any Glock 17 magazine-compatible pistol caliber carbine.
Compatibility and practical applications
For operators running a KRISS Vector configured for Glock 17 magazines, the KRISS USA MAG-EX2 offers a clean upgrade path. Because the kit uses the factory standard Glock magazine body and follower, assembly keeps the original magazine feed geometry intact. That means you get the higher capacity without compromising the proven reliability of Glock magazine internals.
Installed on a pistol-caliber carbine built around Glock 17 magazines, the extension gives competitive shooters and defensive users more rounds on tap during extended drills or defensive scenarios. This is particularly useful for vehicle crews, patrol use, or home defense platforms where additional capacity can reduce the need for immediate reloads under stress.
Why the materials and spring matter
Reinforced composite materials provide a favorable strength-to-weight ratio. The extended spring is tuned to account for the extra stack height and to interface properly with the factory follower — this reduces the risk of follower tilt or pressure inconsistencies that can lead to malfunctions. In short, the kit is designed to augment capacity while preserving the mechanical harmony of the original magazine design.
Installation and maintenance
Installation is straightforward for anyone comfortable performing basic magazine disassembly. The KRISS USA MAG-EX2 outer sleeve replaces the factory baseplate, and the extended spring swaps in for the original. Because the kit retains the factory magazine body and follower, final assembly is quick and intuitive. A careful function check and a few dry-fire reloads will confirm correct engagement before live-fire use.
Routine maintenance is the same as any magazine: periodic cleaning, light lubrication on contact points (avoid over-lubrication), and inspection of the spring for fatigue. The reinforced composites resist corrosion, but treat the assembled magazine with the same care you would give any defensive magazine.

Handling, balance, and tactical considerations
Adding length and rounds changes the center of gravity and handling feel. For pistols, extended baseplates can improve reload leverage and magazine seating during tactical reloads, but they also increase grip profile when the pistol is in the holster. For carbine platforms, the added capacity reduces reload frequency and can be advantageous in close-quarters or high-tempo environments.
Match the KRISS USA MAG-EX2 to your mission profile. If you train regularly with extended magazines, practice insertion and clearing drills to build instinctive handling. For holster carry, verify retention and fit; some holsters accommodate extended baseplates without compromise, others may require an adjustment in carry method.
Durability and long-term use
Reinforced composites are chosen to withstand drops and repeated impacts without the dents and deformation metal can suffer. The spring and follower combination is intended to retain proper tension over many cycles, but like all springs, it should be inspected periodically and replaced when signs of wear appear.
For operators and responsible owners seeking to expand their Glock 17 magazine capacity affordably and reliably, the KRISS USA MAG-EX2 presents a practical option. The kit’s compatibility with the KRISS Vector and Glock 17 magazine-compatible carbines makes it a versatile addition to a defensive kit, available now at a reasonable price point.
