Warne Magazine Extension for Glock 17/22 +5/+4 Black

The Warne Magazine Extension increases capacity in factory Glock 17 and 22 magazines by 5 rounds (9mm) or 4 rounds (.40 S&W), extending reliable feeding without requiring a full extended magazine. Designed for shooters who want extra capacity for competition, range work, or home defense without drastically altering the magazine's profile or balance.

Machined from aircraft-grade aluminum with a durable black anodized finish that resists corrosion and wear. The extension replaces the factory magazine floor plate and spring, using an included higher-capacity spring to maintain reliable feeding. Installation requires disassembly of the magazine—basic mechanical aptitude recommended. The unit adds minimal length while providing measurable capacity gains.
