Description
This is the genuine Ruger factory magazine for your Security-9, and if you run this pistol regularly, having extras on hand makes a real difference. The 17-round capacity gives you a meaningful advantage in both training and home defense setups without the bulk of traditional extended mags. It comes ready to use with a flush-fit floor plate already installed, plus an adapter in the box that lets it fit perfectly in your standard Security-9 configuration.
Construction and Durability of the Security-9 Magazine
The magazine body is made from blued alloy steel that resists corrosion and holds up to regular use. Inside, you get a steel wire spring paired with a polymer follower designed to prevent feed lips from getting snagged, so your rounds feed smoothly every time. An impact-resistant polymer floor plate protects the base during daily handling. Numbered witness holes run down the side so you can count your rounds at a glance without breaking it down.
Compatible Platforms and Real-World Use
Beyond the Security-9 pistol, this magazine also works with Ruger's PC Carbine and PC Charger when used with the SR9/Security-9 magazine well insert. That system compatibility is genuinely useful if you're building out a 9mm platform. The 17-round capacity sits between your standard 15-round mag and the shorter 10-round models, giving you options depending on where you shoot or train. Bear in mind this magazine isn't recommended for the Security-9 Compact, and it won't work with SR9 or SR9c pistols.
Made Right Here in the USA
Ruger manufactures this magazine domestically at their own facilities, which matters to people who care about supporting American manufacturing. It's built to the same tight tolerances as the factory magazines that ship with new Security-9 pistols, so if you've already got experience with those, you know what to expect.

Frequently Asked Questions
Will this 17-round magazine work in my Security-9 Compact?
This 17-round magazine is designed for the full-size Security-9 and isn't recommended for the Compact model. It'll physically fit the Compact but won't sit flush with the grip. If you need more capacity for a Compact, Ruger makes a dedicated 15-round Compact magazine that fits properly.
Does this magazine work with the PC Carbine?
Yes, it works with the PC Carbine when you install the SR9/Security-9 magazine well insert. That insert is a simple swap that takes less than a minute, and once it's in place, Security-9 magazines feed reliably in the carbine. This makes it a good option if you're running both platforms.
What's the difference between this 17-round and the standard 15-round magazine?
The 17-round gives you two extra rounds without a significant difference in size or weight. Both use the same flush-fit design, so the trade-off is basically just two more rounds. The 15-round is what ships standard with Security-9 pistols, but the 17-round is the extended-capacity option when you want maximum firepower.
Are these magazines made by Ruger or a third-party manufacturer?
These are genuine Ruger factory magazines made in the USA at Ruger's own facilities. They're not aftermarket clones. If you've used magazines that came with your Security-9, these are engineered to the same standards and will function identically.
