SHIELD ARMS S15 COMBO PACK: (3) S15 MAGAZINES AND (1) STANDARD STEEL MAG CATCH FOR GLOCK 43X/48
The S15 magazine is a patent-pending, flush-fitting 15-round magazine for the Glock® 43X and Glock® 48. The S15 is a steel magazine, and is the same length as the OEM Glock® 10 round magazine, but holds an additional 5 rounds.
Increased Capacity, Same Reliability
Glock® pistols and magazines are known for reliability, the S15 maintains that same Glock® reliability, while giving you a 50% increase in magazine capacity in the same overall footprint.
Shield Arms accomplished this increased capacity with their patent-pending magazine geometry, allowing the rounds to stagger, thereby fitting more in the same amount of space.
Proudly made in the USA.
Gen 3 Improvements
New US-based manufacturer
Modular tooling
Raised ribs on the back of the magazine to fully match the OEM magazine position in the mag well, which should eliminate any tolerance stacking that results from Glock frame variations
New steel, new coating, new heat treat process, Shield Arms' new steel is slightly thicker, tougher, and now comes with a new standard black nitrocarburized QPQ finish for a high degree of corrosion resistance
QPQ Nitrocarburizing Surface Treatment
QPQ Nitrocarburizing is a type of surface treatment used to enhance the durability and corrosion resistance of metal parts. The process involves heating the metal in a controlled environment, where nitrogen and carbon are introduced to the surface of the metal. This forms a thin layer of a hard compound called "nitrides," which increase the surface hardness of the metal.
During the QPQ Nitrocarburizing process, the metal is immersed in a special salt bath and heated to high temperatures. The salt bath contains a mixture of chemicals that release nitrogen and carbon, which penetrate the surface of the metal. The process is carefully controlled to ensure that the nitrogen and carbon penetrate to a specific depth, creating a uniform layer of nitrides on the metal's surface.
The resulting nitride layer provides many benefits to the metal parts, including increased hardness, wear resistance, and corrosion resistance. This treatment helps to increase the lifespan and durability of metal parts, making them more reliable and long-lasting.
Any “scuffing” you see in the surface finish is completely normal, and will not affect the durability or corrosion resistance of the steel.
Mag Catch Requirement
It is required to swap out your plastic OEM mag catch with either Shield Arms’ standard steel mag catch or their premium steel mag catch. Here's why. If you don't swap your mag catch you may have reliability issues. If you use another manufacturer's mag catch you may have reliability issues. S15 magazines were designed to work with Shield Arms steel mag catches.

Warranty
Like all Shield Arms products, the S15 magazine comes with a 100% lifetime warranty against manufacturing defects. Additionally, they also offer a Spring for Life Guarantee - wear out your spring, get a new one for free, for life.
Standard Steel Mag Catch for Glock 43X/48
Shield Arms’ steel mag catch is required to work with the Shield Arms S15 magazine. Using their steel mag catch with plastic OEM magazines can cause increased wear on plastic mags and OEM mags may not drop free. Shield Arms does not recommend using their steel mag catch with plastic OEM mags. They recommend steel on steel or plastic on plastic.
If you have a first-generation aluminum mag catch, it is required to upgrade to one of Shield Arms steel catch offerings.
