SAR USA ST9 17-Round Magazine — 9mm Luger, Black Polymer (Model: ST917)

Model: ST917 │ UPC: 858763007886

Keep your SAR USA ST9 running at peak performance with the SAR USA ST9 17-Round Magazine (ST917) — a factory-grade, high-capacity replacement magazine engineered to deliver reliable feeding, a slim carry profile, and rugged everyday durability. Whether you’re stocking backup magazines for range sessions, building a carry kit, or replacing worn gear, the ST917 provides OEM-level fitment and dependable function tailored to the ST9 platform.


Built for Reliability and Everyday Use

The ST917 is designed to meet the tolerances and performance expectations of SAR USA owners. Built with a tough polymer body, precision-formed feed lips, and a consistent-pressure spring, this 17-round magazine gives you smooth, positive feeding and dependable lockup in the chassis. It’s a practical balance of capacity and concealability for shooters who want that extra round without compromising handling.


Key Features & Benefits

  • Caliber: 9mm Luger — feeds common self-defense and range ammunition reliably.

  • Capacity: 17 rounds — high-capacity option for range drills and extended sessions.

  • Fitment: Designed specifically for SAR USA ST9 series pistols — OEM compatibility for seamless drop-in function.

  • Body Material: Durable black polymer — lightweight, impact-resistant, and corrosion-proof compared to all-metal magazines.

  • Follower: Anti-tilt polymer follower for consistent cartridge presentation and reduced malfunction risk.

  • Spring: High-tensile, long-life steel spring calibrated for even pressure and extended service life.

  • Baseplate: Low-profile polymer floorplate for a slim carry footprint and quick disassembly for maintenance.

  • Finish: Matte black polymer — non-reflective, discreet, and resistant to scratches and wear.

  • Maintenance: Field-strip friendly — easy to disassemble for cleaning, spring inspection, and replacement.


Performance You Can Count On

From rapid reloads on the range to everyday carry reliability, the ST917 is engineered to perform. The polished feed lips and precisely bent spring geometry help ensure smooth chambering and minimal friction. The anti-tilt follower reduces tilt and hangups, promoting predictable feeding even when cycling rapidly or under stress.


Carry, Concealment & Ergonomics

While offering a generous 17-round capacity, the ST917 maintains a slim magazine profile that complements the ST9’s ergonomics. The low-profile baseplate keeps the grip compact for concealed carry while still offering a positive purchase for reloads. For users who prefer a slightly extended purchase on the mag, compatible extended baseplates and grip sleeves may be available from OEM and aftermarket suppliers.


Easy Maintenance & Longevity

Routine care will keep your ST917 functioning like new: disassemble the magazine by removing the floorplate, inspect and lightly clean the spring and follower, and lubricate sparingly if needed. Replace springs if you notice a drop in spring tension or follower lag — a simple maintenance step that prolongs magazine life and preserves reliability.


Who Should Buy This Magazine?

  • SAR USA ST9 owners looking for factory-fit spare magazines.

  • Concealed carriers who want higher capacity while preserving a slim grip profile.

  • Range shooters and trainers who need extra mags for drills and practice.

  • Armory managers and instructors who prefer OEM parts for predictable performance.
