The Shield Arms S15 Gen 3 magazine transforms the Glock 43X and 48 from single-stack to high-capacity platforms without increasing grip width. This steel magazine holds 15 rounds of 9mm ammunition compared to the factory 10-round capacity, delivering 50% more firepower in the same compact frame.
What Makes This Different
Steel construction enables the magazine body to maintain structural integrity under higher spring tension while supporting more cartridges. The proprietary follower design and spring system accommodate 15 rounds in the same external dimensions as factory magazines. Unlike polymer alternatives, steel construction resists deformation during repeated loading cycles and provides consistent feeding geometry.Key Features
