Construction and Design

The KCI USA magazine body is steel-lined polymer with a hardened steel insert fully encased within the polymer body. The hardened steel insert reinforces the structural integrity of the magazine body at the areas of greatest stress during loading and cycling. The reinforced steel feed lips maintain their geometry under the repeated stress of loading and provide a consistent round presentation at the top of the magazine. The stainless steel spring and injection-molded polymer follower work together to provide consistent upward pressure on the round stack through the full capacity range. Numbered round count witness holes on the body allow for a visual round count check without removing the magazine. The flush-fit design sits flush with the Glock 19 Gen 2 grip frame and the drop-free design allows the magazine to clear the magwell under gravity without requiring manual assistance during a magazine change.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify local and state laws regarding magazine capacity before purchasing.
