Specifically engineered for the all-new Sig Sauer® P320 XTEN 10mm pistol, the Sig Sauer P320 XTEN 10mm 15-Round Magazine is a precision-engineered, factory OEM magazine, designed to deliver smooth, reliable performance in challenging target and tactical environments. The nitride-coated steel body offers superior strength and corrosion resistance, while the high-tensile steel spring and anti-tilt polymer follower deliver smooth feeding performance. The impact-resistant polymer floor plate is easily removed when maintenance and cleaning are required. Better yet, this magazine is equipped with factory-drilled witness holes for quick, visual round counts.
