Durability and Construction
The use of DuPont Zytel polymer gives the PROMAG STANDARD impact resistance and dimensional stability while keeping weight low. The full-length steel internal insert prevents the polymer body from deforming under spring tension and repeated loading, preserving reliable alignment with your pistol’s feed ramp. The injection-molded follower ensures consistent cartridge positioning and the chrome silicone wire spring resists corrosion while maintaining consistent spring tension over time.
Fit, Function, and Applications
Designed specifically for Glock G21 and G30 platforms, the magazine follows factory dimensions to ensure lockup, drop-free function, and smooth feeding. Its 22-round capacity makes it suitable for duty applications where increased rounds are desirable, as well as for extended training sessions at the range. Because there’s no caliber listed, verify with your pistol manual or armorer for cartridge compatibility before use.
Why consider Promag
Promag has a history of producing affordable aftermarket components. The PROMAG STANDARD delivers feature-driven value—steel insert for longevity, corrosion-resistant spring, and American manufacturing—at a price point that makes carrying a spare practical for most shooters. View product details
Buying considerations
