This is a Glock 17, 19, 26 and 34 9mm 33-round extended magazine from KCI.
Providing a high-value alternative to expensive factory Glock magazines, KCI Glock magazines are perfect for rough use, tactical drills, and any other application that might put aggressive wear on magazines and equipment.
These 9mm extended Glock magazines are built with the same polymer and steel design as factory Glock magazines. Designed for use with Glock Gen 3 or later. Internal springs are made from heat-treated chrome silicon wire, and like many new extended magazines might need to be loaded and reloaded several times before accepting full capacity.
As with all extended magazines, these 33-rounders may be difficult to load at first. Consider grabbing a magazine loader to make the process quicker & easier, and remember that the magazines will become easier to reload after multiple loadings.
