Warne Magazine Extension for Glock 42 Black +2/rd

The Warne Magazine Extension for Glock 42 Black +2/rd adds two additional rounds to your Glock 42 semi-automatic pistol, extending magazine capacity without replacing the standard magazine. This firearm-specific extension is engineered by Warne Manufacturing Company to deliver reliable feed and secure retention through real-world duty and training cycles.

The extension features finger grooves machined into the body to enable positive mag manipulation during speed reloads or emergency magazine extraction. The ergonomic profile facilitates one-handed insertion into the Glock 42 frame, a critical requirement for operators managing multiple reloads under stress. Made in America, the black-finished extension resists corrosion and blends seamlessly with the Glock 42's appearance. At 0.06 lbs and compact dimensions (3 x 1 x 7.5 inches), it adds negligible weight and bulk while maintaining the pistol's intended balance and carry characteristics.

This extension is purpose-built for Glock 42 owners prioritizing increased round count without switching platforms—particularly concealed carry professionals, plainclothes officers, and defensive shooters who value the Glock 42's compact profile but need marginally greater magazine capacity. The +2 extension represents a practical middle ground between the factory magazine's base capacity and a full-size duty magazine, enabling quicker reload sequences during training or defensive scenarios while preserving the pistol's handling and concealability.

Warne's magazine extension serves as a proven accessory in the single-stack .380 ACP market, where capacity is often traded against size. This solution directly addresses that trade-off by delivering two additional rounds on an existing magazine platform—a measurable increase in practical firepower without the footprint penalty of upgrading to a larger pistol or magazine system.
