Original Glock plastic magazine base in the familiar, extremely robust Glock polymer material. Fits all double-stack Glock magazines in 9mm, .40 S&W, .380, and .357 SIG calibers. This Glock magazine base is identical to the original, factory-installed one and does not increase the magazine's capacity.
Available in various colors - ideal for color matching your Glock pistol or for easier identification of magazines.
