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.
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.
Mag Catch Recommendation
We recommend swapping out your plastic OEM mag catch with a metal mag catch. Here's why.
- 15 round capacity
- Same length as an OEM Glock 43X/48 magazine
- Easy to remove, impact resistant base pad
- High visibility follower
- High lubricity finish, Black Oxide coating
- Made in the USA
S15 magazines currently come standard with a Black Oxide coating. Black Oxide offers only minimal corrosion resistance, so we recommend that you wipe down the exterior of the magazine with WD40 or your favorite gun lubricant to prevent corrosion.
Electroless nickel coatings are extremely uniform, corrosion and erosion resistant and provide excellent lubricity. If you are in a humid or salt water environment, or if you sweat a lot, we recommend Electroless Nickel or Black Electroless Nickel finish.
See S15 in Electroless Nickel finish here.
Black Electroless Nickel
Black electroless nickel plating combines the same exceptional deposit properties of traditional electroless nickel plating but with conductive, black surface finish. It combines the exceptional lubricity, deposit uniformity, hardness and corrosion resistance of electroless nickel with a fully conductive and uniform black appearance. If you are in a humid or salt water environment, or if you sweat a lot, we recommend Electroless Nickel or Black Electroless Nickel finish.
