Description
This is the genuine factory magazine designed for the SAR USA ST9 full-size pistol. It holds 17 rounds of 9mm Luger ammunition and features a translucent smoke-finish polymer body that lets you see at a glance how many rounds you have loaded without removing the magazine.
The construction combines a durable steel spring with an injection-molded polymer follower to keep cartridges properly aligned and feeding smoothly. The shock-resistant polymer floor plate disassembles easily for field cleaning. Whether you're stocking up for range sessions or just want reliable backups, these magazines are light enough to carry without adding significant weight to your gear.
This is an OEM product from SAR USA, which means it fits and functions exactly like the magazines that come with the ST9. It works flawlessly whether you're training, competing, or putting rounds downrange for practice. Buy a couple of extras so you can reload faster and spend more time shooting.

Frequently Asked Questions
Is this magazine compatible with other SAR pistol models?
No. This ST9 magazine is specifically designed for the SAR USA ST9 full-size pistol only. It will not fit the SAR9 or other SAR compact models. Make sure you're getting the right magazine for your exact pistol model before purchasing.
Can I see how many rounds are in the magazine?
Yes. The translucent polymer construction with a smoke finish lets you quickly count your rounds at a glance without removing the magazine or opening the feed lips. This is convenient during training or when you need to know your ammunition status fast.
How difficult is this magazine to load?
The tapered design makes it easy to seat rounds by hand, though using a speed loader makes the process faster and less fatiguing during extended range sessions. The magazine's polymer body and flexible lips provide smooth, straightforward loading without hangups.
Can I take this magazine apart for cleaning?
Yes. The shock-resistant polymer floor plate comes off easily for field disassembly. You can clean the interior of the magazine, inspect the spring, and put it back together quickly without tools. This helps keep your magazines in top condition.
Is this a genuine OEM magazine?
Yes. This is an original equipment manufacturer magazine made by SAR Arms. It's the same magazine that comes with new ST9 pistols and will function exactly as reliably as the factory-issued magazines.
Why would I need extra magazines for my ST9?
Extra magazines let you reload faster at the range, keep consistent spare magazines for training, or have backup options if one magazine needs maintenance. Running multiple magazines also spreads out wear and extends the life of each individual magazine.
