Shield Arms S15 Magazine for Glock 43x and 48 – 15 Round Magazine

The Shield Arms S15 Magazine is specifically designed for the Glock 43x and 48 models, offering a reliable and durable solution to expand the round capacity of your carry gun. With its impressive capacity of 15 rounds, this magazine provides an extended ammo capacity while not being larger or longer than the standard Glock magazine.

Featuring a sleek and ergonomic design, the Shield Arms S15 Magazine allows for smooth reloading and reliable feeding, enhancing your shooting experience. Whether you’re at the range or in a self-defense situation, this magazine is a trustworthy companion.

The new GEN 3 magazine features raised ribs on the back of the magazine that fully match the OEM magazine position in the magazine well, which should eliminate any tolerance stacking that results from Glock frame variations. New steel, a new coating, and a new heat treat process make this new generation thicker and tougher and now comes with a new standard black nitrocarburized QPQ finish for a high degree of corrosion resistance.

Invest in the Shield Arms S15 Magazine and experience increased firepower, reliability, and convenience with your Glock 43x or 48.


Like all Shield Arms products, the S15 magazine comes with a 100% lifetime warranty against manufacturing defects. Shield Arms also offers a Spring for Life Guarantee – wear out your spring, and get a new one for free, for life.
