ETS Group SG9-320-17 9mm Luger 17rd Clear Detachable Mag - Sig P320

The ETS Group SG9-320-17 is a standard-capacity 9mm Luger double-stack pistol magazine engineered specifically for the full-size Sig Sauer P320. Carrying a flush-fit 17-round count, it mirrors the factory profile of the original Sig magazine while delivering ETS's signature rugged polymer construction.

Built from an extreme impact-resistant advanced polymer, the magazine offers superior resistance to heat, cold, and UV exposure. The translucent clear body lets you visually confirm round count at a glance, and the base plate is interchangeable with the broader ETS line of 9mm double-stack magazines for easy maintenance and field swaps.

Designed as a direct replacement for full-size 9mm Sig P320 pistols, the SG9-320-17 installs flush with the grip frame and feeds reliably through the P320's standard double-stack well. Whether you are stocking a duty pistol, refreshing a range kit, or simply need a durable spare, this ETS mag delivers proven performance at a practical price point.
