Elite Tactical Systems Group (ETS) SIG Sauer P320 9mm 21-Round Magazine – Clear Polymer

The Elite Tactical Systems Group 21-round magazine for SIG Sauer P320 pistols gives you extended capacity in a clear polymer body that lets you verify round count at a glance. Built with ETS's signature translucent construction, this magazine features an anti-tilt follower and reinforced feed lips to ensure reliable feeding through extended range sessions.

Constructed from advanced polymer that won't crack or break when dropped on a loaded magazine, this extended-capacity mag offers superior impact resistance compared to traditional polymer designs. The clear body provides instant visual confirmation of remaining ammunition. Made in the USA. Note: magazines over 10 rounds are restricted in California, Colorado, Connecticut, Hawaii, Maryland, Massachusetts, New Jersey, New York, Vermont, Washington D.C., and other jurisdictions—verify your local laws before ordering.
