You can find the Shield Arms S15 Magazine Combo Pack 1 For Glock 43X/48 Black here.

The Shield Arms S15 Magazine Combo Pack 1 includes three S15 Magazines and one Steel Mag Catch for Glock 43X/48.

The Shield Arms S15 Gen3 Magazine is a 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 with capacity for an additional 5 rounds. Proudly made in the USA.

Firearm: Glock 43X/48
Caliber: 9mm
Capacity: 15
Finish: Black QPQ Nitrocarburizing

S15 Gen3 Improvements:

• New US-based manufacturer
• Modular tooling, allowing Shield Arms to make the S15 and S10 magazines simultaneously
• Raised ribs on the back of the magazine allows Shield Arms 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 - the new steel is slightly thicker, tougher, and now comes with a new standard black nitrocarburized QPQ finish for a high degree of corrosion resistance

Magazine Catch Requirement:
It is required to swap out your plastic OEM mag catch with either a Shield Arms standard steel mag catch or a Shield Arms premium steel mag catch. 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.
