Shield Arms S15 15 Round Magazine for Glock 43X/48, Gen 2

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 either our standard seel mag catch or our premium steel mag catchHere’s whyIf you don’t swap your mag catch you may have reliability issuesIf 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.

  • Easy to remove, impact resistant base pad

    I recently purchased 2 of these magazines for my 43X. They both run flawlessly with approximately 200 rounds through both. Rooftop Defense also needs a mention here: They are awesome! They have that “We take our business seriously, but don’t take ourselves too seriously” mentality and I love it. Thanks again for the noodles, guys! Made my day!

    I was very surprised at the fast delivery. My order was to great satisfaction and the Top Ramen was awesome. Thank you and I will definitely come back.
