SHIELD BASE PLATE FOR GLK 43 +2 BLK

Description

The Shield Arms +2 Magazine Extension is designed for Glock 43 owners who want to carry more rounds without switching to a larger platform. It fits OEM Glock 43 magazines only — not the 43X, 42, or aftermarket tubes — so if you are running factory magazines, this is a direct fit that adds two rounds to your existing capacity.

The extension is machined from billet 6061 aluminum and finished with a Type 2 anodize, which keeps the weight low while giving the surface meaningful resistance to wear and corrosion. Because it replaces the factory floor plate rather than stacking underneath it, the overall profile stays compact enough to clear most aftermarket flared mag wells.

One design detail worth noting is the floor plate itself: it allows you to access the spring and follower for cleaning or inspection without pulling the extension off the magazine body. On a carry gun that sees regular use, that kind of serviceability matters. A replacement power spring ships with the extension, rated at roughly ten percent over standard, which helps ensure reliable feeding with the added column length. Shield Arms backs it with a lifetime warranty and what they call a Spring for Life guarantee on that included spring.

This is a straightforward, domestic-made accessory for a specific purpose — adding capacity to a subcompact carry gun without changing the grip frame or requiring a different holster footprint. It does one thing and does it cleanly.
