.40 S&W Glock compact & subcompact pistols deliver duty-proven performance in an easy-to-conceal package. Combine the hard-hitting firepower of .40 S&W with the ultimate reliability of Glock’s standard factory polymer-and-steel magazines …

These 10-round, compact magazines are designed for use with Glock 23 pistols, but will also fit/function with your Glock 27 (extending below the magazine well) and they’re ideal for training & target practice.

Fits Glock Gen3 and Gen 4 23 and 27 pistols.

Features include numbered witness holes, reinforcing steel inserts, and steel internal spring wire for consistent feeding even in extreme conditions. Trusted by police and military professionals around the globe, Glock factory gear is the only choice for serious shooters. Glock magazines come with a very strong spring rate from the factory to ensure reliability in the toughest of conditions. Sometimes, magazines are found to be a little bit difficult to load at first. However, after a few times loading and unloading, the springs break in nicely and it becomes much easier to load.

We recommend using a magazine loader to ease the loading process.

For added strength and durability factory Glock magazines are steel lined on the interior with a crack resistant polymer body. This increased durability gives officers, military members, and dedicated citizens the confidence that there will be no issues under heavy training.
