Product Details


Manufacturer: Shield Arms
Product Line: S15 Gen2
Compatibility: Glock 43X/48
Caliber: 9mm
Capacity: 15 Rounds
Material: Steel


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.

Gen 2 Improvements

What changed with the gen 2 magazine? We 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

We recommend swapping out your plastic OEM mag catch with our 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 the Shield Arms steel mag catch.


  • 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

Finish Options

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 to prevent corrosion.

Electroless Nickel

Electroless nickel coatings are extremely uniform, corrosion and erosion resistant, and provide excellent lubricity. If you are in a humid or saltwater environment, or if you sweat a lot, we recommend Electroless Nickel or Black Electroless Nickel finish.

Black Electroless Nickel 

Black electroless nickel plating combines the same exceptional deposit properties of traditional electroless nickel plating but with a 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 saltwater environment, or if you sweat a lot, we recommend Electroless Nickel or Black Electroless Nickel finish.
