The ProMag GLKA12 delivers reliable feeding and extended capacity for Glock .40 S&W pistols, offering shooters an affordable alternative to factory magazines. This 15-round magazine fits Glock models 22, 23, and 27, providing increased firepower without compromising reliability.

What Makes This Different

Constructed from DuPont Zytel polymer, this magazine offers superior impact resistance compared to standard plastic alternatives. The reinforced polymer body withstands repeated loading cycles and environmental stress while maintaining dimensional stability. Heat-treated steel springs provide consistent tension across the full 15-round capacity, ensuring reliable feeding even when fully loaded.

Field testing demonstrates consistent feeding across various .40 S&W ammunition weights and profiles.

Law enforcement agencies have adopted similar ProMag designs for duty use, validating the design's reliability under stress. The extended capacity proves advantageous for home defense applications where magazine changes may not be feasible.
