0 failures so far. The trick is to break in the follower spring by loading them and letting them sit. Once the spring is adequately broken in, I had 0 failure to feeds and 0 failure to extracts. All the issues you see are only seen fresh out of the b...

Causing numerous FTF malfunctions by nick, Verified Owner, December 16, 2024
I should have researched this mag more thoroughly before buying it. It's causing multiple failure to feed issues repeatedly. Apparently they work for some people, but it seems most they dont work. Not worth risking these not working when really neede...

Product Info for Shield Arms S15 Gen 3 Glock 48/43X 15 Round Flush 9mm Luger Pistol Magazine

image

The S15 magazine is a Patented, 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.

What changed with the gen 3 magazine? We made the following improvements:

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