The Shield Arms G17ME5BLK is a precision-engineered magazine extension for full-size Glock pistols that adds serious capacity without sacrificing reliability or ease of maintenance. Whether you're running a Glock 19 in 9mm or a Glock 23 in .40 S&W, this billet aluminum extension delivers an extra 5 rounds (9mm) or 4 rounds (.40 S&W) while maintaining the ergonomic profile shooters expect from quality Glock accessories. Built from 6061 aluminum and finished with Type 2 hard anodizing, it's designed to handle the demands of training, competition, and defensive carry.
What sets this extension apart is the thoughtful engineering behind it. The unique easy-access floor plate design lets you service the magazine spring and follower without ever removing the extension from the mag body—a real time-saver when you're maintaining gear. Index cuts machined into the body give you better purchase when stripping mags from a pouch, and it plays nicely with most aftermarket flared mag wells. Shield Arms backs every extension with their Spring for Life guarantee and a 100% lifetime warranty, so you know you're investing in gear that will last.
This extension fits OEM Glock 13 and 15-round magazines and ships complete with a +10% power spring matched to handle the extra rounds. Made in the USA, it's the kind of upgrade that keeps you training longer on your current magazine supply without compromise. Note that the magazine itself is not included—this is purely the extension and spring.
