Apex Tactical Specialties FNX 45 Magazine Extension Plus 2

The FNX Magazine Base Pad Extension increases capacity by two and a half (2.5) rounds for standard FNX 45 model pistol magazines. The design philosophy behind the 2.5-round increase—rather than 2 or 3—reflects Apex’s engineering approach: the extension accommodates 2 additional rounds while preserving enough compression space in the magazine spring to ensure a fully loaded magazine seats properly with the slide in battery.
