The FAB Defense Glock 43 Plus Four Extension is a magazine floor-plate replacement for the Glock 43 that adds four rounds for a total of 10 rounds in a magazine. The special ergonomic design enables secure manipulation of the magazine and a full grip on the weapon when the magazine is in use. The extension has a matt black, fiberglass reinforced polymer construction with contoured finger indents and the innovative spring plate allows the use of the original magazine spring. NOTE: On 2021, Glock added an extra coil to their magazines so you can only fit three extra rounds with this extension if you have the 2021 Glock model.
