Glock Magasin G31 +1 16rd .357 SIG BLACK FOLLOWER,

This 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.
