This is an extended .40 S&W 31-round magazine for Glock 22, 23, 27, and 35 pistols
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 31-round extended magazines feature polymer and steel construction, just like standard factory magazines, and are designed to work with Glocks that have the ambidextrous mag release (Gen 3, 4 and 5). 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.
Loading to half capacity and leaving overnight will ease future loadings.
