The ETS Group 30-round extended 9mm magazine for Sig P320 gives you serious capacity without sacrificing reliability. Built from advanced polymer, this smoke-tinted mag holds more rounds than factory options while maintaining the same dependable feed performance P320 shooters expect. Whether you're running drills at the range, building a competition setup, or simply want extended firepower on the clock, a 30-round mag transforms your P320 into a high-capacity platform without a caliber change.
ETS magazines are engineered for real-world use: the translucent polymer body lets you see your round count and ammo type at a glance, and the specially designed base plate disassembles easily for cleaning or spring maintenance. The ergonomic floor plate is shaped to grab quickly from mag pouches, and the creep-resistant feed lips won't spread or degrade even after long-term storage fully loaded. You get legitimate durability here—impact-resistant polymer that won't crack when dropped, excellent chemical resistance, and thermal stability across cold and hot extremes.
Compatibility is straightforward: this 30-rounder fits the Sig P320 Compact. ETS also offers 15, 17, and 21-round capacities in the same line with interchangeable base plates, so you can build a modular magazine ecosystem around your platform. The lifetime warranty backs the engineering.

This magazine is made for 9mm Sig P320 Compact. ETS manufactures magazines for different platforms and calibers, but they are not interchangeable across different firearm models or calibers. Verify your specific gun model before ordering.
Yes—the base plates are interchangeable across the ETS line of 9mm double-stack magazines (available in 15, 17, 21, and 30-round capacities). This lets you swap components if needed, though each magazine body is caliber and platform-specific.
The smoke-tinted body allows you to see your remaining round count and ammo type without removing the magazine, helping you manage capacity during competition, training, or duty rotation. The polymer is also resistant to impact, chemicals, and extreme temperatures, so you get durability and utility in one design.
