The Glock 43 Magazine calibre 9 x 19mm is a composite steel and polymer fabrication. The slimline mag encases a toughened and hardened steel insert in Polymer 2. The result is the steel insert protects the magazine lips. As a consequence of the slimline design the capacity is only 6 rounds.
Glock Magazine Polymer 2
Polymer 2 is more resilient than steel. The consequence is this composite magazine assembly can withstand a lot of abuse and still continue functioning. Glock magazines withstand visible damage or deformation after being dropped on solid floors from serious height.
Reliable Ammunition Feeding:
Selected and expertly heat treated steels form the spring. As a result spring tension lasts for years. As a result of the accurately manufactured spring and follower, the Glock Magazine feeds ammunition with total reliability.
