The SAR ST45 is a solid .45 pistol, and one thing every .45 owner learns fast is that you can never have too many magazines. This is the genuine factory 10-round magazine built for the ST45, made by Sarsilmaz and imported through SAR USA, so it drops in and runs exactly like the one that came in the box with your pistol. No fitment guesswork, no aftermarket surprises.
The body is steel, which handles the wear and tear of range life and holster carry without warping or denting easily. Inside you get a polymer follower that keeps rounds tracking straight up the feed lips, paired with a quality spring that keeps consistent pressure from the first round to the tenth. The polymer base plate rounds out the package and takes the abuse of dropping loaded mags on concrete during reloads. The whole thing wears a black matte finish that stays low-key and resists corrosion.
This mag holds 10 rounds of .45 ACP and measures about 7.15 inches long, giving you a full-size grip fill for the ST45. Whether you're stacking mags for a range day, building out a home defense setup, or just want a backup in the bag, factory magazines like this one are the reliable choice. Aftermarket options can be hit or miss with a .45, so sticking with OEM takes the feeding drama out of the equation.
Bottom line, if you own an ST45, an extra factory mag or two is money well spent. More time shooting, less time reloading between strings, and the peace of mind that your spare will run just as clean as your primary.
Yes, this is an original equipment (OEM) magazine made by Sarsilmaz and brought in through SAR USA, the exclusive U.S. importer. It fits and functions just like the magazine that shipped with your ST45, so you get the same feeding reliability without any aftermarket compromises.
This magazine is built specifically for the SAR USA ST45 chambered in .45 ACP. It is not designed for other SAR models like the K245 or SAR9 series, since those use different mag bodies and feed geometry. Stick with this one if the ST45 is what you're running.
It holds 10 rounds of .45 ACP and gives you a full grip fill on the ST45. If you want a couple extra rounds, SAR also makes a 12-round version for the same pistol.
The body is steel for durability and dent resistance, with a polymer follower and polymer base plate inside. A quality spring keeps steady pressure on the stack, and the black matte finish helps fend off corrosion during regular carry and range use.
