Warne MEG43X2BLK 6061-T6 Aluminum Magazine Extension with Hardcoat Anodized Black Finish for Glock 43X/48 (Adds 2 Rounds)

The Warne MEG43X2BLK is a magazine extension built for Glock 43X and 48 shooters who want practical capacity gains without sacrificing concealability. Machined from 6061-T6 aluminum and finished with Type 2 hardcoat anodize, this extension adds 2 rounds to your factory magazine while maintaining the slim profile that makes these compact 9mm pistols so appealing for carry. If you run your Glock 43X or 48 for self-defense, duty, or range work, an extra pair of rounds in the magazine is real-world useful—especially in a gun designed around efficiency.

The ergonomic shaping and finger grooves aren't just cosmetic; they genuinely improve how the magazine seats and strips from the gun, which matters when speed and reliability count. The hardcoat anodize stands up to holster wear, sweat, and rough handling far better than bare aluminum would, and a Torx head screw with washer locks everything together securely. This is a made-in-the-USA component built to the standards you'd expect from a maker known for quality optics mounts—attention to detail matters in the details.

If your state or range has magazine capacity limits, Warne also offers zero-capacity models; this particular extension is the +2 version. Pair it with your existing factory mags and you've got a simple, durable way to squeeze a bit more utility out of a gun that's already been engineered for carry-first performance.
