Warne Magazine Extension Features The Warne Magazine Extension is machined from 6061-T6 aluminum and finished with a hardcoat anodized black coating giving it the durability to handle repeated insertion and removal from the magwell. Designed specifically for Glock 42 magazines chambered in .380 ACP this extension adds two rounds of additional capacity giving shooters more rounds on tap before needing to reload. Its ergonomic shape is engineered to allow smoother more reliable insertion into the pistol reducing the chance of a fumbled reload under pressure. This attention to fit and function makes it a practical upgrade rather than a purely cosmetic addition. Finger grooves molded into the extension allow the magazine to be stripped from the handgun quickly when necessary aiding faster reloads or magazine changes. Because the extension is purpose-built for the Glock 42 platform it integrates cleanly with the factory magazine body without requiring any additional modification. The black anodized finish matches the pistol s factory appearance keeping the overall look clean and cohesive. For Glock 42 owners looking to squeeze a bit more capacity out of their everyday carry magazines the Warne Magazine Extension offers a simple effective solution.
