SAR USA ST917 ST9 Black Detachable 17rd Magazine for 9mm Luger

The SAR USA ST917 is a 17-round 9mm magazine purpose-built for the SAR ST9 handgun. If you run an ST9 for duty, sport shooting, or backup carry, having reliable factory magazines on hand isn't just convenient—it's essential. This detachable magazine gives you the capacity and dependability your ST9 was designed around.

Build quality matters in a magazine. SAR engineered the ST917 with a high-quality spring and polymer follower to feed rounds consistently under real-world conditions. The polymer base plate is durable enough for range sessions and duty use, while the black finish resists corrosion. Whether you're practicing at the range, running steel courses, or keeping your ST9 ready for serious use, a second or third magazine reduces downtime and keeps your gun in the fight.

SAR magazines are straightforward pieces of kit—they don't need to be fancy, just reliable. The ST917's 17-round capacity makes it a practical choice for shooters who want full-power firepower without sacrificing ergonomics or concealability compared to some extended alternatives. This is a factory-spec magazine, so you know it'll perform exactly as SAR intended.
