50% MORE Capacity Than Factory Magazine, SAME Size!

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.
Shield Arms accomplished this increased capacity with their patent-pending magazine geometry, allowing the rounds to stagger, thereby fitting more in the same amount of space.

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

And now Shield Arms offers the S15 with a Powercron finish.

What is Powercron?

Powercron is a cationic epoxy coating that offers excellent corrosion resistance and low VOC in a lead-free film electrocoat surface finish. If you are in a humid or saltwater environment, or if you sweat a lot, Shield Arms recommends Powercron.

Specifications

  • 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
  • Patent-pending

Shield Arms recommends swapping out your plastic OEM mag catch with either their standard steel mag catch, or 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, they recommend upgrading to one of their steel mag catch offerings.
