Shield Arms S15 Magazine Gen 3 15rd Flush 9mm Luger Fits Glock 48/43X Nickel Steel SAS15NGEN3

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. What changed with the gen 3 magazine? We made the following improvements: US-based manufacturer. Modular tooling. Raised ribs on the back of the magazine allows these 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 – new steel is slightly thicker, tougher, and now comes with a new standard black nitrocarburized QPQ finish for a high degree of corrosion resistance
