Increase your Glock 43x/48 capacity by 50%.
The Shield Arms 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. Sheild Arms has accomplished this increased capacity with their patent-pending magazine geometry, allowing the rounds to stagger, thereby fitting more in the same amount of space.

Gen 2 Improvements
What changed with the gen 2 magazine? Sheld 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 recommends swapping out your plastic OEM mag catch with one of their mag catches. 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, they recommend upgrading to one of their steel mag catch offerings.
