The KCI USA 26-Round .45 ACP Magazine is a replacement magazine for Glock 21, 30 and 41 pistols from KCI USA (part no. KCI-MZ013). KCI builds it around a hardened steel insert encased in polymer, the same steel-and-polymer approach used in factory Glock magazines. The polymer coating protects the body from deformation, even when the magazine is dropped from a height. Viewing holes show how many rounds are left, which keeps range sessions and drills moving without guessing. At 26 rounds it gives a .45 ACP Glock a lot more shooting between reloads for range days and training.
