This is a factory SIG P320 10-round magazine in 9mm.

This magazine also fits full-size SIG P250 pistols.

This SIG P320 10-round magazine features a steel construction, side-facing witness holes, and an impact-resistant polymer baseplate.

Please note: that this is a full-size magazine blocked at 10-rounds and will fit in full-size P320/P250 pistols. This Sig Sauer magazine is compliant with States and counties with high capacity restrictions (New York, California, Cook County, etc.). Additionally, this magazine is not compatible with the Sig Sauer P211 GTO with a factory magazine well installed.

Having spare magazines for any firearm is a must. Quality magazines don’t go bad, and extra mags allow you to keep your pistol functioning at peak performance.
