The ProMag GLK 18 is a Glock 36 extended magazine that brings 10-round capacity to this compact .45 ACP platform. Where the factory magazine holds 6 rounds, this aftermarket option nearly doubles your ammunition count while maintaining a profile suited for concealed carry. ProMag engineered this magazine specifically for the G36's single-stack frame, giving shooters who carry this slim .45 a practical capacity upgrade without switching to a bulkier pistol. We stock this magazine for customers who want more rounds on tap from their Glock 36 without compromising the handgun's concealable dimensions.
ProMag builds this magazine around a proprietary DuPont Zytel-based polymer body reinforced with a full-length steel internal insert. This hybrid construction delivers the corrosion resistance of polymer with the structural rigidity that steel provides under spring tension. The injection-molded follower tracks consistently through the extended body, while the heat-treated chrome silicon wire spring maintains reliable feeding pressure across temperature extremes. The black polymer finish matches OEM aesthetics and resists wear from repeated holster contact. Each magazine ships with ProMag's lifetime manufacturer's guarantee against defects, reflecting their confidence in the design. Browse our full magazines selection for additional pistol and rifle options.
This extended magazine serves Glock 36 owners who prioritize capacity for home defense or range training sessions where frequent reloads interrupt the shooting rhythm. The 10-round count also satisfies magazine capacity restrictions in several states, making it a practical choice for those navigating compliance requirements. Pair this magazine with a quality Glock holster and reliable handgun ammunition to complete your carry setup. We recommend confirming function with your specific firearm and preferred defensive loads before relying on any aftermarket magazine.
