Shield Arms S15 15 RD Glock Magazine G48 & 43X 9MM SA-S15-PC



Shield Arms S15 15 RD MAGAZINE FOR THE GLOCK G48 & 43X 9MM SA-S15-PC. These are the Generation 2 ambidextrous magazines. 

Shield Arms recommends using a metal magazine catch when using metal magazines in the Glock 48 or Glock 43X.


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 by Check-Mate.

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 catchHere'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 the Shield Arms steel mag catch.
