P320 X-five Legion Magazine - Black, 9mm, 10/rd

The P320 X-Five Legion Magazine in black, chambered for 9mm with a 10-round capacity, is purpose-built for competitive shooters, duty officers, and defensive pistol users who demand magazine reliability without compromise. Sig Sauer engineered this magazine to complement the P320 X-Five Legion platform—a pistol renowned for precision and speed. Whether you're running competition circuits, qualifying on a law enforcement range, or maintaining a duty-ready defensive setup, this magazine delivers the performance standard you've come to expect from Sig's Legion line.

Built with Sig's proven magazine geometry and robust construction, the P320 X-Five Legion Magazine features a witness hole for round-count verification at a glance—critical when reloading under stress or managing range inventory. The 10-round capacity complies with restricted-state carry requirements while maintaining the same mechanical reliability as higher-capacity variants. Anti-tilt followers, reinforced spring rates, and a durable blued-steel body ensure consistent feeding through the P320's optimized feed ramp, eliminating the common failure point many shooters encounter with lesser magazines. The magazine's lip design resists deformation during repeated insertions and removals, extending service life across thousands of cycles.

This magazine is compatible exclusively with Sig Sauer P320 X-Five Legion and standard P320 platforms in 9mm Luger. Law enforcement agencies running the P320 as their duty pistol, competitive shooters in IPSC or USPSA formats, and civilians in states with 10-round magazine limits will find this magazine indispensable for maintaining reliability and compliance. Rotate in multiple magazines to distribute wear, and inspect followers and springs annually if your P320 sees frequent use. Purchasing extras ensures you always have a fresh magazine in rotation and a proven backup ready for duty or competition.
