Each GLOCK magazine is constructed with a hardened steel insert encased in high tech polymer to protect the magazine from 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. This factory magazine will fit the GLOCK 22, 23, 24, 27, & 35 models chambered in .40 S&W.
These mags are GREAT to carry as spare mags to give you some extra ammo for defensive situations, and they are GREAT at the range!
