Glock G21 21 G41 41 13rd 45acp Magazine - Each GLOCK magazine is constructed from a hardened steel insert encased in high tech polymer to protect the magazine and prevent deformation, even when dropped from a great height. The high quality spring and follower ensure reliable feeding from the first round fed by a fully compressed spring down to the last shot. Its double cut magazine body also works with a reversed magazine catch on Gen 4 GLOCK pistol models.
