Shield Arms Glock 19/23 +5/+4 Magazine Extension Black

The Shield Arms Glock 19/23 +5/+4 Magazine Extension is a black aluminum base extension for Glock magazines. It adds capacity to a standard magazine body, with the extension sized for the Glock 19 and 23 in 9mm Luger and 40 S&W.

The extension is machined from 6061 aluminum and finished in Type 2 anodizing. It adds 5 rounds to a Glock 19 or 23 magazine in 9mm and 4 rounds to a Glock 23 magazine in 40 S&W. The floor plate design lets you access the spring and follower without removing the extension, and index cuts on the body improve grip when drawing the magazine from a pouch.

The package includes a +10% power spring. The extension fits OEM Glock magazines only.
