The Apex Tactical Specialties +2 magazine extension for the FNX-45 adds two rounds to a standard FNX-45 magazine, bringing capacity to 15 rounds per the manufacturer. It replaces the factory floor plate as a direct swap, so shooters running the FNX-45 Standard or FNX-45 Tactical can pick up extra .45 ACP on board without changing their reload. We carry this for owners who want more rounds in the gun for range work, competition, or duty carry, and for anyone topping off spare mags before a match.
This base pad is machined from aluminum and wears an anodized finish, so it holds up to repeated loading and hard use without chewing through the way a polymer pad can. The low-profile design keeps the extension tight against the magazine body for secure carry and a clean draw, and the added length gives the magazine a more weight-balanced feel in the hand. Apex builds this part specifically for the FNX-45 platform, so the fit follows the factory magazine geometry rather than forcing a universal pad onto the gun. The result is a +2 capacity bump that maintains dependable feeding and function, which is the whole point of swapping a base pad in the first place.
Installation is a direct replacement for the factory base plate and takes only basic disassembly of the magazine, with no gunsmithing required. Shooters who carry the FNX-45 for defense or duty will appreciate the extra two rounds without adding a second magazine to the belt, and competition shooters get a higher round count between reloads. As with any capacity change, confirm reliable function with your carry ammunition after installing it. See the Apex FNX 45 mag extension product listing for current stock and pricing.
