Apex Tactical Specialties FNX 45 Mag Extension +2 – FN FNX-45

The Apex FNX 45 Mag Extension increases capacity by 2 rounds for FN FNX-45 magazines, bringing standard 15-round magazines to 17 rounds. This extension replaces the factory magazine baseplate while maintaining reliable feeding and a clean profile that doesn't interfere with magazine changes or holster fit.

Machined from aluminum with a durable anodized finish, this extension installs using the factory magazine spring and follower—no additional parts required. Installation is straightforward: remove the factory baseplate, install the extension, and reassemble. The extension adds minimal length while providing a slightly extended gripping surface for faster reloads.
