Warne Mag Ext Sigp320 +3 De

The Warne Mag Ext Sigp320 +3 De is a premium magazine extension designed specifically for the SIG Sauer P320 platform, adding three rounds of capacity to the original magazine while maintaining reliable feeding and consistent performance. This extension is ideal for armed professionals, competitive shooters, and serious enthusiasts who require enhanced magazine capacity for their P320 during training or duty scenarios.

Machined from 6061 T6 aluminum billet and finished with Type 2 hardcoat anodize, this extension provides the durability and corrosion resistance operators demand in high-round-count training and duty environments. The hardcoat anodize finish resists both abrasion and environmental corrosion, critical for weapons carried in varied climates or salt-air environments. At 0.13 lbs, the extension adds negligible weight to the magazine, preserving the P320's handling characteristics.

Those operating in high-round-count scenarios—patrol duty, advanced force-on-force training, or multi-stage competitions—benefit from the additional reserve capacity without sacrificing draw speed or holster retention. The P320's modular design ecosystem means this extension is compatible with various configurations of the P320 platform.
