Construction and Design

The magazine body is polymer with a hardened steel insert that reinforces the feed lips and body structure along the areas that experience the most stress during loading and cycling. The stainless steel spring resists corrosion and maintains consistent feed tension across the full 10-round capacity. The polymer follower guides the top round into a consistent feed position as the magazine empties. Numbered witness holes along the body allow round count verification without removing the magazine from the pistol. The flush fit design keeps the base of the magazine even with the bottom of the grip frame, maintaining the standard Glock 17 grip profile. The drop-free design allows the magazine to fall clear of the mag well under its own weight when released.

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.
