SHIELD BASE PLATE FOR GLK 19 +5 BLK

Description

The Shield Arms Magazine Extension for the Glock 19 is built for shooters who want meaningful additional capacity without swapping to a larger-frame pistol. By replacing the factory floor plate with a machined aluminum body, it adds five rounds to a standard Glock 19 9mm magazine, letting the gun carry more ammunition while keeping the same grip frame and holster fit.

The extension is machined from billet 6061 aluminum and finished with a Type 2 anodize, which keeps weight down compared to a steel alternative while providing a hard, corrosion-resistant surface. The floor plate itself is designed to open without first removing the extension from the magazine body — a practical detail that matters when you need to clean the follower channel or inspect the spring after a range session rather than partially disassembling the magazine to get there. Index cuts along the extension body give your fingers something to register against when stripping the magazine from a pouch under stress.

A higher-rate spring ships with the unit to keep reliable feeding at the extended stack length. Shield Arms backs the extension with a lifetime warranty and their Spring for Life guarantee covering the included spring. The extension is compatible with OEM Glock magazines and fits most aftermarket flared mag wells. It is made in the USA.
