The Glock 43x Extended Magazine Release/Glock 48 Extended Magazine Release is CNC Machined from aerospace-grade aluminum and merges flawlessly with the ergonomics and styling of G43x/48 handguns. In addition to functioning exactly like an OEM release the profile of Glock 43x and 48 Extended Mag Release is slightly raised with chamfered edges which helps ensure that you eject your Glock 43x or 48 magazines quickly and with ease.
