Shield Arms S15 magazine for GLOCK 43X / 48, 9mm, 15 rounds. Gen 3. Nitrocarb finish

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.
Proudly made in the USA.
Mag Catch Recommendation:   Shield Arms recommends swapping out your plastic OEM mag catch with their steel mag catch.  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 only. If you have a first generation Shield Arms aluminum mag catch, it’s recommended that you  upgrade to a steel mag catch.  Purchase steel mag catches:  HERE .
