Warne MESIG54DE 6061-T6 Aluminum Magazine Extension, Hardcoat Anodized Flat Dark Earth Finish, Adds 5 Rounds for Sig P320 9mm Luger Magazines

The Warne MESIG54DE magazine extension is a straightforward way to add capacity to your Sig P320 9mm magazines. Built from 6061-T6 aluminum and finished in hardcoat anodized Flat Dark Earth, this five-round extension stacks durability and practical aesthetics into a small package. If you run a P320 for duty, sport shooting, or self-defense and want a few extra rounds on tap without swapping mags, this extension bridges the gap between your standard magazine and a full-size reload.

The hardcoat anodize finish means this isn't just a cosmetic choice—it's a protective coating that resists wear, corrosion, and the scuffs that come with regular handling and carry. The 6061-T6 aluminum alloy is a proven material in precision machining, chosen for strength-to-weight balance and reliability under stress. Unlike some magazine accessories that feel loose or rattle, a solid extension like this one should seat firmly and feed consistently when you need it.

Installation and removal are typically straightforward with mag extensions—no special tools required. The FDE color coordinates well with modern tactical setups and blends naturally with most P320 platforms and holster systems. Whether you're building out a home-defense rig, stocking spares for the range, or looking to add insurance to your carry setup, this extension gives you a quick capacity boost without the bulk of switching to a different magazine altogether.
