Elite Tactical Systems Group SIG P320 9mm 21-Round Magazine – Transparent Polymer Construction

The ETS 21-round magazine for SIG Sauer P320 pistols delivers extended capacity in a lightweight, transparent polymer design. The clear body allows instant visual confirmation of remaining round count without removing the magazine from the firearm. ETS magazines feature advanced ergonomic geometry that enhances grip purchase during reloads and extreme impact resistance that exceeds traditional polymer magazine standards.

Constructed from a proprietary polymer blend, this magazine is compatible with all P320 full-size and compact variants chambered in 9mm. The floor plate is removable for easy disassembly and cleaning. The magazine ships fully assembled and ready to use. Note: magazines exceeding 10-round capacity are restricted or prohibited in California, Colorado, Connecticut, Hawaii, Maryland, Massachusetts, New Jersey, New York, Vermont, Washington D.C., and other jurisdictions with magazine capacity limits. Verify local and state laws before purchasing.
