Fab Defense Handgun Magazine Extension Glock 43 +4 - Black

The Fab Defense Handgun Magazine Extension Glock 43 +4 in Black is a precision-engineered magazine floor-plate replacement designed for concealed carry professionals and duty personnel who require reliable capacity without compromising concealability. This extension adds four rounds to the Glock 43 magazine, resulting in a total capacity of 10 rounds (+4 extension), which is a critical advantage in defensive scenarios where every round counts.

Built to integrate seamlessly with the factory magazine body, the Fab Defense FX-4310B extension requires no modifications to your firearm or existing gear. It features ergonomic contouring for secure manipulation during tactical reloads and emergency mag changes, even under stress or with gloved hands. Manufactured from reinforced polymer composite, the extension maintains a slim profile essential for appendix or IWB carry while withstanding repeated duty-cycle use.

This extension is ideal for law enforcement, armed security, and civilian defensive carriers relying on the Glock 43 as a primary or backup firearm. The black finish matches factory Glock aesthetics and resists environmental wear, ensuring durability and functionality. Installation is straightforward—simply replace the factory floor-plate with the extension floor-plate; no gunsmithing is required.
