The Shield Arms S15® Starter Kit is the most affordable and convenient way to upgrade your Glock® 43X® or Glock® 48 from 10 rounds to 15 rounds of 9mm capacity. This complete bundle includes both essential components needed for a seamless capacity upgrade: one Gen 3 S15® magazine and one precision-engineered steel magazine catch designed specifically for the S15® system.
The S15® Starter Kit saves you money compared to purchasing components separately. It's the perfect entry point for shooters new to the S15® system who want to experience 50% more capacity without sacrificing the slim, concealable profile that makes the Glock® 43X®/48 ideal for everyday carry.
What's Included in Your S15® Starter Kit
(1) Shield Arms S15® Gen 3 Magazine
Capacity: 15 rounds (50% more than OEM 10-round magazines)
Construction: Premium steel with patented staggered-round geometry
Durability: Prevents reliability issues caused by plastic catch wear with steel magazines
Dual Compatibility: Standard catch works with both S15® steel magazines AND OEM plastic magazines
Important: Using S15® magazines with the OEM plastic magazine catch will result in accelerated wear and reliability issues. The steel mag catch is mandatory for optimal S15® performance.
Why Choose the S15® Magazine System?
The Shield Arms S15® magazine uses a patented double-stack design with a single-stack footprint, giving you 50% more capacity than factory Glock® magazines without adding bulk or requiring extended base pads. The S15® Starter Kit provides the most affordable entry point into the S15® system while maintaining the slim, concealable profile your Glock® 43X®/48 is known for.
