ProMag GLKA14 Glock 30/21 Magazine 13rd .45 ACP DuPont Zytel

The ProMag GLKA14 delivers reliable feeding and extended capacity for Glock 30 and 21 pistols chambered in .45 ACP. This aftermarket magazine extends your firepower beyond factory limitations while maintaining the dependable function shooters demand. Built from DuPont Zytel polymer with a heat-treated chrome silicon spring, it provides consistent performance across thousands of rounds.

What Makes This Different

Unlike standard 10-round Glock 30 magazines, the GLKA14 provides 13 rounds of .45 ACP capacity in a package that maintains proper grip ergonomics. The DuPont Zytel construction offers superior impact resistance compared to standard polymer blends, while the precision-molded feed lips ensure consistent cartridge presentation. The magazine body features reinforced stress points that handle repeated loading cycles without cracking or deformation.
