Glock 31 Magazine

DescriptionnThe Glock 31 magazine (calibre 357 SIG) 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. Invented by Gaston Glock himself, Polymer 2 is a high strength nylon based polymer. As a result, this polymer makes the Glock Magazine incredibly durable.nnPolymer 2nPolymer 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 will withstand visible damage or deformation after being dropped on solid floors from serious height.nnReliable Ammunition Feeding:nThe Glock 31 magazine spring is made from selected and expertly heat treated steels. As a result of the accurately manufactured spring and follower, the Glock Magazine feeds ammunition with total reliability. The magazine body has twin cuts. Due to this the Glock 31 Magazine is compatible with all Glock Gen 4 semi auto pistols with the magazine catch in left or right handed configuration.
