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.
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 by Check-Mate.
