Glock 43X/48 15-Round 9mm Magazine

Glock 43X/48 15-Round 9mm Magazine

Product Description

The Glock 43X and Glock 48 platforms have become extremely popular for concealed carry due to their slim profile and improved ergonomics, but many owners look for higher-capacity magazine options beyond the factory 10-round configuration. The most widely recognized upgrade is the Shield Arms S15 Gen 3 magazine, which increases capacity to 15 rounds while maintaining a near flush-fit profile.

The Gen 3 S15 uses hardened steel construction with updated geometry, reinforced feed lips, and improved magazine catch surfaces compared to earlier generations. These magazines are specifically engineered for Glock 43X and Glock 48 pistols and are commonly paired with a steel magazine catch for improved long-term durability and reliability.
