This is the factory OEM Taurus GX4 9mm 13 Round Magazine. This Taurus GX4 extended magazine holds up to 13 rounds of 9mm ammunition, thanks to its Plus 2 grip extension.
This Taurus GX4 magazine is made of reinforced steel, providing for reliable EDC. The polymer follower and steel spring work fluidly with each other, making feeding and loading incredibly smooth and simple. The staple Taurus high visibility follower (yellow) allows you to safely tell when your magazine is empty and that your chamber is clear. A capacity count is featured down the spine of the magazine. This alerts you to how much 9mm ammunition you have left to load, or to fire. The polymer baseplate provides a good degree of comfortability and stability as well.
