Shield Arms S15 Magazine – Glock 43X/48

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.

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.

Black oxide finish.

Since the S15 magazine is all steel, the replacement of the stock polymer magazine catch with a metal magazine catch is highly recommended.

This Gen 2 version has the following improvements over the Gen 1:

• Ambidextrous – magazine catch cutout on both sides
• Smaller mag catch cutout windows
• Improved magazine tube geometry
• Improved baseplate geometry
