The 33 round GLOCK magazine – sometimes referred to as a “Happy Stick,” 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. Reliability if the going gets tough. Exactly what one would expect from a genuine “Glock Precision” engineered product.
