Shield Arms SAS15ME5RED 5-Round Magazine Extension for S15 Magazine - Red Anodized Aluminum

The Shield Arms SAS15ME5RED is a 5-round magazine extension for the Shield Arms S15 magazine, designed to boost capacity while maintaining the compact, ergonomic footprint shooters rely on in modern carry guns. Built from billet 6061 aluminum and finished in red Type 2 anodize, this extension pairs clean aesthetics with serious durability. It's engineered for the shooter who wants more rounds on board without sacrificing concealability or shootability.

What sets this extension apart is the easy-access floor plate design. You can service, clean, or maintain the magazine body without removing the extension itself—a thoughtful detail that saves time at the range or when maintaining your gear. Machined index cuts along the extension body give you positive grip when drawing from a mag pouch, so you're not fumbling with a slippery aluminum tube during reloads. The extension ships with a 12-coil plus power spring, giving you reliable feeding right out of the box. It fits most aftermarket flared mag wells, so compatibility shouldn't be an issue whether you're running an S15 in a competition gun or a duty setup.

This is a USA-made product backed by Shield Arms' lifetime warranty and Spring for Life guarantee, so you're investing in a piece you can count on for years of shooting. If you're running an S15 magazine and want to pack five more rounds without compromise, this extension delivers both function and form.
