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.
Shield Arms accomplished this increased capacity with 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.
Gen 2 Improvements
What changed with the gen 2 magazine? Shield Arms made the following improvements:
Ambidextrous - mag catch cutout on both the left and right side
Smaller mag catch cutout windows
Improved magazine tube geometry
Improved baseplate geometry
Mag Catch Recommendation
Shield Arms recommend swapping out your plastic OEM mag catch with either our standard steel mag catch or our premium steel mag catch. Here's why. If you don't swap your mag catch you may have reliability issues. If you use another manufacturer's mag catch you may have reliability issues. Gen 2 magazines were designed to work with Shield Arms steel mag catches. If you have a first generation aluminum mag catch, we recommend upgrading to one of our steel mag catch offerings.
15 round capacity
Same length as an OEM Glock 43X/48 magazine
Easy to remove, impact resistant base pad
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 your favorite gun lubricant (we like EEZOX) to prevent corrosion.
Like all Shield Arms products, S15 magazine comes with our 100% lifetime manufacturer's warranty against manufacturing defects. Additionally, they also offer a Spring for Life Guarantee - wear out your spring, get a new one for free, for life from Shield Arms.
