Fab Defense Magazine Extension for Glock 42 +4/rd

The F.A.B. Defense Magazine Extension for Glock 42 +4/rd is a magazine floor-plate replacement system designed to extend the capacity of the Glock 42's factory magazine from six rounds to a total of ten rounds. This Israeli-engineered extension provides a practical solution for those who carry the Glock 42, enhancing its ammunition capacity without altering the firearm's slide, frame, or internal mechanics.

The extension features contoured finger indents for secure magazine manipulation during tactical reloads and malfunction drills. Its specialized spring-plate design maintains proper round stacking and ensures reliable feeding through the factory feed lips. Weighing just 0.13 lbs, the extension adds negligible weight, and its compact profile of 3.5 x 1.6 x 5.55 inches helps prevent printing when carried.

This extension is ideal for Glock 42 operators, including off-duty law enforcement, plainclothes security personnel, and civilians who prioritize concealability without sacrificing magazine capacity. The ergonomic design allows for a full firing grip when the extended magazine is in use, addressing the limitations of smaller single-stack magazines. While the extension is designed to fit in holsters compatible with factory Glock 42 magazines, users should verify compatibility with their specific holster model.
