High-Capacity Magazine for Glock 43X and 48

The Shield Arms S15 Gen 3 is a purpose-built magazine that solves a real problem for compact Glock shooters: how to carry more ammunition without sacrificing the slim profile that makes these pistols so appealing.

What Makes It Different

Shield Arms engineered the S15 with patent-pending geometry that staggers rounds more efficiently than conventional designs. The result is a flush-fitting magazine that holds 15 rounds while maintaining the exact length of Glock's factory 10-round magazine. You get a 50% increase in capacity without changing your carry footprint.

Gen 3 Improvements

The latest generation reflects Shield Arms' commitment to refinement:

  • New domestic manufacturing ensures consistent quality and faster availability
  • Raised ribs on the magazine back precisely match the factory mag well, eliminating tolerance stacking issues
  • Enhanced steel with improved thickness and toughness
  • QPQ nitrocarburized finish provides exceptional corrosion resistance through a hardened surface layer

Built to Last

The QPQ nitrocarburizing process creates a uniform layer of hard compounds on the steel surface, dramatically improving durability and rust resistance. This professional-grade treatment is the same technology used in demanding industrial applications.

American Made

Proudly manufactured in the USA with the same reliability standards that Glock shooters expect and depend on.
