The Glock 25 Magazine is a composite steel and polymer fabrication. The Glock magazine encases a toughened and hardened steel insert in Polymer 2. This steel insert protects the magazine lips. Gaston Glock invented Polymer 2 which s a high strength nylon-based polymer. As a result of this polymer jacket, the Glock Magazine is incredibly durable.
Polymer 2 is more resilient than steel. Consequently, this composite magazine assembly can withstand a lot of abuse and still continue functioning. Especially relevant is that the Glock magazine withstands visible damage or deformation after being dropped on solid floors from serious height.
Reliable Ammunition Feeding:
The Glock 25 magazine spring is made from selected and expertly heat treated steels. As a result of the accurately manufactured spring and follower, the G25 mag feeds ammunition with total reliability.
