Warne 3113 Glock 17/22 Magazine Extension +5/4rd Aluminum FDE

The Warne 3113 Magazine Extension transforms standard Glock 17 and 22 magazines into higher-capacity powerhouses, adding 5 rounds to 9mm configurations and 4 rounds to .40 S&W setups. This precision-machined extension addresses the common need for increased ammunition capacity without compromising reliability or concealment profile.

What Makes This Different

Unlike polymer alternatives that can crack under stress, this extension features 6061-T6 aluminum construction with military-grade hardcoat anodizing in Flat Dark Earth. The material choice provides exceptional durability while maintaining a lightweight profile that won't significantly alter the pistol's balance. The anodized finish resists wear, corrosion, and maintains its appearance through thousands of loading cycles.

Key Features

• Adds 5 rounds to Glock 17 (9mm) magazines, 4 rounds to Glock 22 (.40 S&W)
• 6061-T6 aluminum construction for superior strength-to-weight ratio
• Hardcoat anodized Flat Dark Earth finish resists scratches and corrosion
• Maintains reliable feeding with factory Glock magazine springs
• Low-profile design preserves concealability in most holsters
• Precision-machined tolerances ensure consistent magazine function
• Compatible with standard Glock 17 and 22 factory magazines

Field testing demonstrates consistent feeding reliability across various ammunition weights and manufacturers. The extension maintains proper spring tension throughout the extended capacity range, preventing the feeding issues common with inferior magazine modifications. Competition shooters appreciate the reduced reload frequency during stages, while duty officers benefit from increased on-board ammunition without carrying additional magazines.
