Description
The SAR Arms ST9 9mm 10-round magazine is the genuine factory equipment for ST9-series pistols. This is a straightforward, dependable spare or replacement magazine built to the same specifications and tolerances as the magazines that came with your firearm.
SAR Arms ST9 Steel Construction
Built from quality alloy steel with a durable matte black finish, this magazine handles regular use without fussing. The steel body keeps the magazine feeling solid, and the matte finish resists showing scratches and wear that catches the eye on shiny surfaces. The polymer follower and spring work together to keep rounds seated properly and feeding cleanly when you need them.
10-Round Capacity for the ST9
Holding a full 10 rounds, this magazine gives you reliable capacity without bulking up your carry setup or gear bag. The mag itself stays compact and manageable, whether you're rotating between a few magazines at the range or keeping one as a spare in a range bag.
Built for Real Use
Factory-spec magazines just work. You don't have to wonder about fitment or feeding issues because these were designed in the factory for your gun. The polymer base plate pops on and off for simple field cleaning, and the interior design keeps ammunition properly aligned during feeding cycles. Keep a couple on hand for range days, training sessions, or whenever you want an extra mag in your rotation.

Frequently Asked Questions
Will this SAR ST9 magazine work with other pistols?
No, this magazine is designed specifically for SAR USA ST9 pistols. It won't fit other platforms. If you own an ST9, these are your factory-compatible option for spares or replacements.
What's the difference between the 10-round and higher capacity ST9 magazines?
This is a 10-round magazine. SAR also makes 17-round magazines for the ST9, which hold more rounds but create a larger footprint. Choose based on your preferred mag capacity and whether you prioritize shorter magazines for concealed carry or higher capacity for extended range sessions.
How do I clean this magazine?
The polymer base plate is removable for simple cleaning and maintenance. You can field strip it without tools to clean the interior spring and follower if needed. It's a straightforward process that takes seconds.
Are these actual factory SAR magazines?
Yes, these are OEM magazines made to Sarsilmaz factory specifications and tolerances. They're the same magazines that ship with new ST9 pistols, just sold separately as spares or replacements.
