This quality replacement magazine for a Glock & is constructed from steel and polymer just like the factory Glock mags. Each will work with all generations of Glock's including those with ambidextrous magazine releases & can be rebuilt using factory magazine parts. Note: Like many new magazines, these have an extremely stiff spring from the factory. It may not be possible to initially load them to capacity. Loading half of the listed capacity and leaving it loaded overnight before the first use will ease future loadings.
