Magpul PMAG 27 GL9

The Magpul PMAG 27 GL9 delivers serious extended capacity for Glock-pattern firearms, packing 27 rounds into a package that remains practical for most applications. While too long for concealed carry in pistols, the 27-round magazine is ideally suited for pistol caliber carbines, home defense setups, range training, and competition shooting where capacity matters.

Built with the same reinforced polymer construction as the entire GL9 line, the 27-round magazine maintains Magpul's high standards for reliability. The extended steel spring is precisely calibrated for the longer column of ammunition, ensuring consistent feeding from bottom to top. The four-way anti-tilt follower prevents the nose-diving that plagues many extended magazines.

This magazine has become a favorite among PCC shooters, particularly those running Glock-compatible carbines like the CMMG Banshee or Ruger PC Carbine. The added capacity reduces reload frequency during matches or training sessions, while the proven Magpul reliability prevents the feeding issues common with many extended magazines. At roughly $20, it's also one of the most affordable high-capacity 9mm options available.
