Sig Sauer, Zev technologies Z320 Octane 9mm pistol. This firearm comes with one magazine. This is an extended magazine, and appears to have come from a larger Legion series gun. This firearm is in good condition, but does show some signs of carry wear. We are in Arizona, and the left side of this gun appears to have some spotting from sweat salts, mostly at the rear serrations and back of slide.
The rifling in the barrel looks good.
