853465008995 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 What changed with the gen 3 magazine? We made the following improvements: New US-based manufacturer Modular tooling, allowing us to make the S15 and S10 magazines simultaneously Raised ribs on the back of the magazine allows us to fully match the OEM magazine position in the mag well, which should eliminate any tolerance stacking that results from Glock frame variations New steel, new coating, new heat treat process - our new steel is slightly thicker, tougher, and now comes with a new standard black nitrocarburized QPQ finish for a high degree of corrosion resistance. Mag Catch Requirement It is required to swap out your plastic OEM mag catch with either our standard steel mag catch or our 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. S15 magazines were designed to work with Shield Arms steel mag catches. Specifications 15 round capacity Same length as an OEM Glock 43X/48 magazine Easy to remove, impact resistant base pad High lubricity finish options Made in the USA Patent-pending

Description:

Elevate your shooting experience with the S15 9MM Luger Magazine.

The S15 magazine is a patent-pending, flush-fitting 15 round magazine designed specifically for the Glock® 43X and Glock® 48. This innovative magazine offers increased capacity while maintaining the same reliability you expect from your Glock.

Features:

  • 15 round capacity
  • Same length as the OEM Glock® 10 round magazine
  • Constructed from durable steel
  • Easy to remove, impact resistant base pad
  • High lubricity finish options
  • Manufactured in the USA
  • Patent-pending design

What’s New with the Gen 3 Magazine?

We’ve made several improvements to enhance performance:

  • New US-based manufacturer
  • Modular tooling for simultaneous production of S15 and S10 magazines
  • Raised ribs on the back of the magazine for a perfect fit in the mag well, eliminating tolerance stacking caused by frame variations
  • New steel, coating, and heat treat process for improved durability and corrosion resistance with a standard black nitrocarburized QPQ finish

Mag Catch Requirement

To ensure optimal reliability, it is necessary to replace your plastic OEM mag catch with either our standard steel mag catch or our premium steel mag catch. Failure to do so may result in reliability issues, especially if using a mag catch from another manufacturer. The S15 magazines are designed to work seamlessly with Shield Arms steel mag catches.

Upgrade your Glock® 43X or 48 with the S15 magazine and experience the difference in capacity and performance.
