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.
Shield Arms accomplished this increased capacity with their patent-pending magazine geometry, allowing the rounds to stagger, thereby fitting more in the same amount of space.
Proudly made in the USA.
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 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. Gen 2 magazines were designed to work with Shield Arms steel mag catches. If you have a first generation aluminum mag catch, we recommend upgrading to one of our steel mag catch offerings.
- 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
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.
Powercron is a cationic epoxy coating that offers excellent corrosion resistance and low VOC in a lead-free film electrocoat surface finish. If you are in a humid or salt water environment, or if you sweat a lot, we recommend Powercron, Electroless Nickel, or Black Electroless Nickel finish.
Note: because we have multiple Powercron vendors, there may be slight cosmetic variations in the finish. This is cosmetic only and does not affect performance. If you are concerned about a “matching” finish from mag to mag, you might be happier with one of the electroless nickel finishes.
Like all Shield Arms products, the S15 magazines comes with their 100% lifetime warranty against manufacturing defects. Additionally, they also offer a Spring for Life Guarantee – wear out your spring, get a new one for free, for life.
