ProMag GLKA9B StandardBlack DuPont Zytel Polymer Detachable 18rd 9mm Luger for Glock 17/26/19

The ProMag GLKA9B is an 18-round 9mm Luger magazine engineered for Glock 17, 19, and 26 pistols. If you carry a modern Glock or own one of the many rifles and carbines built on Glock-pattern magazine compatibility, this polymer magazine solves the capacity question without breaking the bank. It's made in the USA from DuPont Zytel polymer—the same material trusted in countless duty and civilian applications for its durability and longevity.

Built around a heat-treated chrome-silicon wire spring, the GLKA9B maintains consistent tension through the magazine's life, reliably feeding round after round downrange. Whether you're running a concealed-carry G19, full-size G17, or subcompact G26, this magazine feeds them all. It's also compatible with the growing ecosystem of 9mm Glock-pattern carbines and PDWs, making it a smart choice if you're standardizing ammunition and magazines across multiple platforms.

The all-black finish keeps it low-profile and easy to identify in your gear. At 18 rounds, you're getting more on-tap capacity than factory Glock magazines without the bulk or weight penalty of steel. ProMag has been making aftermarket magazines for decades—this is a no-frills, straightforward option for shooters who want extra magazines without the premium price tag.
