Shield Arms Extended Magazine for Glock 17 9mm 22-Round

The Shield Arms Extended Magazine is a 22-round 9mm handgun magazine built on a genuine Glock 17 OEM magazine body. A machined 6061 aluminum billet extension adds five rounds of capacity, so the magazine body does not need to be replaced with an aftermarket part.

The extension has Type 2 anodized black finish for corrosion resistance and durability under repeated insertion and removal. Index cuts on the extension aid grip when drawing the magazine. An included plus-10% power spring is designed to keep feeding reliable at the extended capacity. The floor plate can be removed to service the spring and follower or clean the magazine body without taking off the extension.

The extension is designed for OEM Glock magazines and fits Glock 17, Glock 19 and Glock 19X. It is chambered for 9mm Luger and is made in the USA.
