Glock 65971 G17/G34 33-Round Extended Magazine 9mm Black Polymer

The Glock 65971 extended magazine transforms standard capacity firearms into high-capacity platforms, delivering 33 rounds of 9mm ammunition in a factory-engineered polymer construction. This extended magazine eliminates frequent reloading during competitive shooting and extended range sessions while maintaining Glock's legendary reliability standards.

What Makes This Different

Unlike aftermarket alternatives that often suffer from feeding issues, this factory Glock magazine undergoes the same rigorous testing as standard capacity magazines. The extended body maintains the same spring tension and follower geometry as shorter magazines, ensuring consistent feeding from the first round to the last. The polymer construction weighs significantly less than steel alternatives while providing superior corrosion resistance in harsh environments.

Competitive shooters rely on this magazine for USPSA Production Division matches where capacity advantages translate to stage wins.

Law enforcement agencies appreciate the sustained fire capability during training exercises, and the magazine's durability withstands thousands of loading cycles without spring fatigue.
