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.

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.

The S15 is currently only setup for right handed mag catch (left side of pistol). We are currently working on an ambi version, release TBD.

Proudly made in the USA by Check-Mate.


We recommend swapping out your plastic OEM mag catch with a metal mag catchHere's why.
