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. 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.
