ETS Group 31-Round Extended Pistol Magazine, Gen2 Floor Plate, 9mm Luger for Glock 17/18/19/19X/26/34/45, Clear Blue Polymer

The ETS Group 31-round extended pistol magazine for 9mm Luger is a high-capacity option built for Glock 17, 18, 19, 19X, 26, 34, and 45 platforms. This clear blue polymer magazine uses an improved Gen2 floor plate and refined internal geometry designed to feed reliably across a wide variety of ammunition, from brass to steel and aluminum casings. If you're running drills at the range, stocking up for duty or sport shooting, or simply want more rounds between reloads, an extended-capacity magazine trades slightly more weight and grip profile for genuine utility.

The clear polymer body lets you verify your round count at a glance—a small but practical detail when you need to know where you stand in the middle of a session. The Gen2 floor plate engineering reflects the lessons learned from the original design, with geometry tuned specifically to handle feeding consistency. ETS Group magazines have earned a solid reputation in the practical shooting community for reliability under real-world conditions.

Magazine capacity sits at 31 rounds, giving you a meaningful increase over factory 17-round magazines for Glock 17-size frames while remaining practical to carry and deploy. The bright blue finish is unmistakable, making it easy to spot and sort your magazines at a glance.

Frequently Asked Questions

Which Glock models does this magazine fit?

This ETS Group magazine is compatible with Glock 17, 18, 19, 19X, 26, 34, and 45 chambered in 9mm Luger. All generations of these models should accept the magazine with the Gen2 floor plate.

Will this magazine feed all types of 9mm ammunition?

Yes. The improved internal geometry is engineered to feed reliably with brass, steel, and aluminum cased ammunition, so you're not locked into a single ammo type.

Why choose a 31-round magazine over factory capacity?

Extended-capacity magazines are popular for range training, competition, and high-volume shooting disciplines where magazine changes become a limiting factor. You get more rounds downrange between reloads, which is especially useful during drill work or courses of fire.

Can I see how many rounds are loaded?

The clear blue polymer body includes a visibility window, so you can quickly verify your round count without removing the magazine from the gun.
