The S15 magazine is a Patented, flush-fitting 15 round magazine for the Glock® 43/48. The S15 is a steel magazine, and is the same length as the OEM Flock® 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.

We accomplished this increased capacity with our 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 process - our new steel is slightly thicker, tougher, and now comes with a new standard black nitrocarburized QPQ finish for a high degree of corrosion resistance
