ETS GLK9170 27-Round Extended 9mm Magazine for Glock Clear Polymer

The ETS Group GLK9170 delivers extended capacity without sacrificing reliability, providing 27 rounds of 9mm ammunition in a competition-legal magazine. This clear polymer magazine offers visual round counting and enhanced capacity for competitive shooting applications.

What Makes This Different

Unlike standard factory magazines, the GLK9170 features translucent polymer construction that allows instant visual confirmation of remaining ammunition. The extended 27-round capacity provides a significant advantage over standard 15-17 round magazines while maintaining full compatibility across multiple Glock generations. The competition-legal design meets most match requirements while delivering the reliability expected from quality aftermarket magazines.
