The S15 Gen 3 magazine is a Patented 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.
- Sheila 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.
Gen 3 Improvements- Raised ribs on the back of the magazine allows us 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 - our 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.
Silver Nickel Coating - Nickel coatings are extremely uniform, corrosion and erosion resistant and provide excellent lubricity.
Made in the USA
Mag Catch Requirement- It is required to swap out your plastic OEM mag catch with either our standard steel mag catch or our 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 their 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. This magazine cannot be shipped to the following states: California, Colorado, Connecticut, D.C., Hawaii, IL, Maryland, Massachusetts, New Jersey, New York, Vermont & WA
