Shield Arms S15 Gen3 Magazine for Glock 43X / 48 - Nitrocarb, 15 rounds

The Shield Arms S15 Gen3 is a 15-round steel magazine designed specifically for the Glock 43X and Glock 48. Its patented staggered-round geometry increases capacity by 50% compared to the standard 10-round OEM magazine while maintaining the same flush-fit profile and overall length as the original magazine.

The Gen3 version features a reinforced steel construction with improved material thickness and toughness, while the QPQ Nitrocarburized (Nitrocarb) finish provides enhanced resistance to wear and corrosion. Raised ribs on the rear of the magazine help ensure proper positioning in the magazine well, while the impact-resistant base pad can be easily removed. The magazine is made in the USA and is backed by a lifetime warranty, including the manufacturer's Spring for Life program.

For proper function, the S15 Gen3 is designed to be used with a Shield Arms steel magazine catch rather than the standard polymer Glock magazine catch. The magazine has a 15-round capacity and retains the compact dimensions of the OEM 10-round magazine.

Parameters:

• For Glock 43X/48 pistols
• Caliber: 9x19
