Introducing the Glock 17 OEM magazine, enhanced with a Shield Arms +5 magazine extension. This is not just any magazine; it represents an evolution in capacity and functionality for your Glock 17. Constructed from robust materials, this magazine features a durable anodized finish that resists wear while providing a sleek profile. The unique easy access floor plate design allows you to service or clean the interior of the magazine body without removing the extension. This means less hassle and more time on target. The extended capacity adds five additional rounds to your standard loadout, taking full advantage of your Glock's capabilities. With a total of 17+5 rounds at your disposal, you can engage with confidence knowing that you'll have ample ammunition when it matters most. This product includes an upgraded spring—10% stronger than standard—to ensure reliable feeding under all conditions. The index cuts on the extension provide improved grip during reloads, making sure you maintain control even in high-pressure situations. Designed specifically to fit only OEM Glock magazines, this extension integrates seamlessly into your existing setup while fitting most aftermarket flared mag wells as well. It’s machined from billet 6061 aluminum and finished with Type 2 anodizing for added durability and resistance against corrosion. Every component is proudly made in the USA and backed by Shield Arms’ unwavering commitment to quality; hence comes with a lifetime warranty alongside their Spring for Life guarantee—a testament to their confidence in both craftsmanship and performance. Note: If you're using this enhancement on a Glock 19X model, be advised that removal of the lanyard loop will be necessary for proper fitment. In summary, if you're seeking increased firepower combined with ease of maintenance—all wrapped up in American-made reliability—the Glock 17 OEM +5 Magazine Extension by Shield Arms stands ready to serve you faithfully on every outing.
