The Shield Arms S15 magazine is a testament to innovation in firearms technology, specifically designed for the discerning Glock® 43X and Glock® 48 owner. In the world of self-defense and precision shooting, capacity matters. This patent-pending marvel offers a significant leap forward by providing a flush-fitting design that packs 15 rounds into the same footprint as your standard OEM Glock® magazine. Crafted from robust steel, the S15 embodies reliability synonymous with Glock®, while enhancing it with an impressive 50% increase in ammunition capacity. This feat is achieved through Shield Arms' ingenious geometry that allows staggered round placement without altering the overall size—a prime example of American ingenuity at work. With its latest generation updates, this magazine features several advancements: sourced from a new US-based manufacturer using modular tooling techniques ensures consistent quality across models. The raised ribs on its spine offer seamless integration within your firearm's mag well—addressing any variances caused by frame differences. Shield Arms elevates durability further with their QPQ Nitrocarburizing treatment—a process where nitrogen and carbon are infused onto metal surfaces in controlled settings to form nitrides. These enhance wear resistance and corrosion resilience significantly ensuring longevity under harsh conditions; normal scuff marks don't compromise these qualities whatsoever.
