Shield Arms S15 Gen 3, 15rd, GLOCK 43x / GLOCK 48 Magazine

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.

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.

Shield 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.

Proudly made in the USA.

Gen 3 Improvements

What changed with the gen 3 magazine? We made the following improvements:

New US-based manufacturer

Modular tooling, allowing us to make the S15 and S10 magazines simultaneously

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 pro(more...)
