The Kriss USA Mag-Ex2 Extension Kit transforms a standard Glock 17 Gen3–5 magazine into a 40-round powerhouse for 9mm Luger. Built from reinforced composite materials, this extension system pairs proven Glock reliability with serious capacity gains—ideal for shooters running Kriss Vector carbines, Glock handguns, or any Glock-compatible PCC who need extended range between reloads. The kit includes everything you need: an extended baseplate, outer sleeve, and extended spring, all engineered to feed and function without compromise.
Magazine capacity matters in a firefight or at the range, and the Mag-Ex2 delivers a practical 23-round boost over factory Glock 17 specs. The polymer construction keeps weight down while the outer sleeve reinforces the magazine body, and the extended spring maintains reliable feeding shot after shot. Color-matched black finish integrates seamlessly with modern Glock aesthetics and tactical setups.
Caliber specificity is built into the design—this kit is engineered for 9mm Luger to ensure proper spring tension and follower interaction. Whether you're running it in a Vector, a host Glock 17, or a dedicated mag-fed carbine platform, the Mag-Ex2 delivers the capacity and dependability shooters expect from Kriss engineering.
