The Glock MF33009 G33 9-round magazine in .357 Sig is the factory-original choice for shooters running Glock's hard-hitting .357 Sig pistols. Built to Glock's exacting standards, this magazine combines a hardened steel feed lips and spring with a durable polymer body—a proven design that feeds reliably and resists damage from drops and rough handling on the range or in the field.
If you're serious about your .357 Sig Glock, you want factory magazines you can trust. These are engineered to work flawlessly with your pistol right out of the box, though like all new Glock magazines, they can feel tight when loaded to full capacity. The spring compresses over a few days of normal use, or you can accelerate the break-in by loading the magazine to full capacity and cycling it repeatedly from full to empty. This is normal and not a defect—it's the price of a spring that's built stiff enough to reliably feed round after round, year after year.
For hunters, competitive shooters, or anyone who carries a .357 Sig, having reliable factory magazines on hand is essential. These are drop-free magazines, so they'll release cleanly every time you reload, and the rugged polymer construction means they'll take the punishment your training or hunting trips can dish out.

Frequently Asked Questions
Will this magazine work with my Glock G33?
Yes—this is the factory Glock magazine designed specifically for the Glock G33 in .357 Sig. It is engineered to feed and function reliably in that platform.
Why is the magazine so hard to load when it's new?
New Glock magazines have stiff springs to ensure long-term reliability. Load it fully and let it sit for a few days to allow the spring to compress, or cycle it repeatedly from full to empty to speed up the break-in. This stiffness is a feature, not a flaw—it ensures your magazine will feed reliably for years.
Is this a factory Glock magazine or an aftermarket copy?
This is a factory-original Glock magazine (model MF33009). It is made to Glock's specifications and backed by the reliability Glock is known for.
