The Fab Defense Magazine Extension For Glock 42 +4/Rd transforms the compact Glock 42 magazine into a more controllable and higher-capacity platform. This 42-10 floor-plate replacement adds four additional rounds of .380 ACP while its fiberglass reinforced polymer body and contoured finger grooves provide a secure, comfortable grip during reloads and shooting.
Designed specifically for the Glock 42, this extension maintains the use of the original magazine spring and offers a full firing grip without adding unnecessary bulk. It is well suited for concealed carry, range practice, and training sessions where extra capacity and improved handling are beneficial. Fab Defense continues to be recognized for thoughtful engineering and durable accessories that enhance real-world firearm performance.
