Odin Works Magazine Extension for SIG P320 +5 – Black

The Odin Works Magazine Extension for SIG P320 adds 5 additional rounds to factory 17-round magazines, bringing total capacity to 22 rounds. Designed for competitive shooters and those who prioritize extended capacity without changing grip length, this extension maintains reliable feeding while reducing reload frequency during range sessions or competition stages.

CNC-machined from 6061-T6 aluminum with a Type III hard anodized black finish for corrosion resistance and durability. The extension installs without permanent modification to the magazine—simply remove the factory baseplate, install the provided extension spring, and attach the Odin Works baseplate. No gunsmithing required. The aluminum construction adds minimal weight while providing a positive grip surface during reloads.
