S15 Magazine Gen 3 Combo 15rd (3 Mags)

Upgrade your Glock 43X or 48 with the Shield Arms S15 Combo 1, a complete high-capacity magazine package designed for increased firepower, durability, and reliability. This combo includes three Gen 3 S15 steel magazines and one black nitride steel mag catch, ensuring seamless compatibility and superior performance.

Each S15 magazine is flush-fitting and staggered, holding 15 rounds in the same footprint as the OEM 10-round magazine. Constructed from heat-treated stainless steel, these magazines are available with three premium coatings:

QPQ Nitrocarburizing – Enhanced hardness, wear resistance, and superior corrosion protection
Silver Nickel – Highly uniform, corrosion-resistant, and provides excellent lubricity
Black Nickel – Offers all the benefits of electroless nickel plating with a sleek black finish

To ensure optimal function and longevity, the S15 magazines require replacing the OEM plastic mag catch with a Shield Arms steel mag catch. This prevents excessive wear and ensures flawless magazine retention and feeding. If you are still using a first-generation aluminum mag catch, upgrading to a steel version is required for full reliability.
