Shield Arms® S15 Gen3 Glock 43X/48 magazine / 15 rounds, caliber 9×19mm

The Shield Arms S15 Gen 3 magazine is a game-changer for every Glock 43X or 48 owner. With a capacity of 15 rounds in a standard magazine size and innovative steel construction, it offers the ideal combination of compactness, durability and maximum firepower. The third generation adds entirely new manufacturing facilities, more robust materials and higher compatibility with the weapon frame.

Even more rounds without compromise

Thanks to its thoughtful design, it completely replaces the original polymer magazines. Whether you aim for higher capacity or greater durability, the S15 Gen 3 fulfills both. It holds 15 rounds of 9×19mm caliber in dimensions that remain fully compatible with the weapon frame. And since it does not increase the size or profile of the firearm, it is perfect for everyday carry.

New material, new processing

The third generation of S15 magazines is produced by a new manufacturer in the USA, featuring a completely new exterior – stronger and tougher steel, black QPQ nitride finish (Quench-Polish-Quench), and a new heat treatment process. The result is a magazine with higher resistance to corrosion and wear, able to withstand harsh handling.

Exactly where it should be

One of the main design improvements are the elevated guide ribs on the rear of the magazine. They allow for a perfect fit in the weapon frame and eliminate problems associated with manufacturing tolerances in various Glock frames. The magazine thus fits tightly and functions consistently in any compatible firearm.

More than just increased capacity

Modular tools allow for the production of various types of magazines on a single line, thus Shield Arms enhances quality and availability. Whether it's ten-round (S10) or fifteen-round (S15) magazines, the quality remains top-notch.

Metal catch as a necessity

Because the magazine is completely metal, it is necessary to replace the original plastic magazine catch with a metal one. Only this way can you ensure smooth operation, long service life and maximum reliability with each insertion and exchange.
