Warne 3126 Aluminum Magazine Extension Glock 19/23 +5/+4 Rounds

The Warne 3126 Magazine Extension transforms standard Glock 19 and 23 magazines into higher-capacity platforms without sacrificing reliability. This precision-machined aluminum extension adds 5 rounds to 9mm magazines and 4 rounds to .40 S&W magazines, providing tactical advantages when capacity matters most.

What Makes This Different

Unlike polymer extensions that can crack under stress, the Warne 3126 uses aircraft-grade 6061-T6 aluminum construction with hardcoat anodizing for superior durability. The machined aluminum body maintains consistent spring tension across the extended capacity range, ensuring reliable feeding through the entire magazine. This extension integrates seamlessly with factory Glock magazines without requiring permanent modifications or voiding warranties.

Key Features

• 6061-T6 aluminum construction with hardcoat anodized black finish
• Adds 5 rounds to Glock 19 9mm magazines (20 total capacity)
• Adds 4 rounds to Glock 23 .40 S&W magazines (17 total capacity)
• Compatible with factory Glock 19 and 23 magazines

Competitive shooters and law enforcement professionals rely on the Warne 3126 for matches and duty applications where reload frequency reduction provides tactical advantages. The aluminum construction withstands repeated loading cycles and impact stress better than polymer alternatives. Extended magazines function reliably in both concealed carry and duty holsters designed for standard Glock magazines, though overall length increases by approximately 1.2 inches.
