For shooters who demand reliable feeding, consistent fit, and affordable spare magazines for duty or range use, the right magazine can make a measurable difference in performance and readiness. Selecting a magazine that matches your platform and shooting needs ensures smooth reloads and fewer interruptions during training or defensive scenarios.

PROMAG SIG P320 is a blued steel magazine designed specifically for use with a Sig P320 chambered in 9mm and offers a 17-round capacity.

Design and construction

The PROMAG SIG P320 uses blued steel construction for the body and follower, prioritizing durability and reliable feeding under repeated use. Blued steel provides a balance of hardness and corrosion resistance when properly maintained, making it a practical choice for a service-style magazine that will see regular cycling and storage.

Capacity and form factor

With a 17-round capacity, this magazine increases available rounds over standard 15-round options while maintaining a compact profile that works well with standard P320 grips and holsters. The 17-round configuration supports sustained drills and tactical reloads without dramatically changing balance or concealment dynamics for users who train regularly.

Performance for 9mm platforms

Chambered in 9mm, the PROMAG SIG P320 benefits from the caliber’s manageable recoil, wide ammunition availability, and proven terminal performance for defensive and practice use. A 17-round magazine maximizes the common advantages of 9mm—higher capacity and controllable follow-up shots—making it ideal for tactical training, duty carry, or range sessions.
