Description
When it comes to spare mags, there's no good reason to gamble on aftermarket. These are straight from Ruger, built to the same specs and tolerances as the magazines that came with your SR9, SR9C, or 9E from the factory. The steel body construction, polymer follower, and steel wire spring all work together to keep rounds feeding cleanly and consistently, whether you're running drills at the range or topping off before a long day.
The numbered witness holes on the side make it easy to do a quick round count without having to drop the mag and guess, which is a small feature that gets appreciated more the longer you shoot. The flat polymer baseplate keeps the profile clean, and the overall build feels solid in hand without being unnecessarily heavy.
One thing worth knowing about the SR9C specifically: this is the full-size 17-round SR9 magazine, not the compact 10-rounder. It will function in the SR9C, but Ruger recommends using their magazine adapter (sold separately, part 90341) to keep the mag properly seated and aligned in the compact frame. That extra length actually gives you a nice grip extension when running the compact gun, which some people prefer.
These magazines are also compatible with the Ruger PC Carbine and PC Charger when used with the SR9/S9 magazine well insert, making them a solid investment if you're running that rifle and any of these pistols as a matched pair. Having your pistol and carbine share the same magazines is one of the big practical advantages of the PC Carbine platform.
Getting two at once is just practical. You'll go through rounds faster than you think, and having a second mag loaded and ready keeps your range time moving. These are made in Italy, widely believed to be manufactured by Mec-Gar, which is one of the most respected magazine manufacturers in the world. Genuine Ruger part number 90449.

Frequently Asked Questions
Will this 17-round magazine work in my SR9C compact?
Yes, the full-size SR9 17-round magazine will function in the SR9C, but it extends below the grip frame since the SR9C was designed around a shorter 10-round mag. Ruger recommends using their magazine adapter (part 90341, sold separately) with the SR9C to keep the mag properly aligned in the grip. Many SR9C owners actually prefer the SR9 mag in this setup since it gives a full grip purchase and extra capacity.
Are these genuine Ruger magazines or aftermarket?
These are genuine Ruger factory magazines, part number 90449. They're manufactured to the same specifications and tolerances as the original magazines that came with your firearm. The magazines are widely believed to be produced by Mec-Gar in Italy, which is one of the most respected OEM magazine manufacturers in the industry.
Can I use these SR9 magazines in a Ruger PC Carbine?
Yes. These magazines are compatible with the Ruger PC Carbine and PC Charger when the SR9/S9 magazine well insert is installed in the rifle. This is one of the practical advantages of the PC Carbine platform, the ability to share magazines across your Ruger pistol and carbine. Note that the SR9C compact magazines are not compatible with the PC Carbine, so make sure you're using the full-size SR9 17-round version.
What features do these magazines have for practical use?
The magazines feature numbered witness holes along the side so you can check your round count at a glance without dropping the mag. The steel wire spring and polymer follower work together for reliable feeding and consistent cartridge alignment. The polymer baseplate keeps the overall profile clean, and the blued steel body is built to hold up to regular range use.
Why buy a 2-pack instead of a single magazine?
At the range, a single spare magazine means you're reloading constantly instead of shooting. Having two loaded mags ready to go keeps things moving during drills and practice sessions, and it's more economical than buying them one at a time. It also makes sense to have a true backup, since magazines are wear items and can occasionally need replacing after years of heavy use.
Do these magazines fit the Ruger 9E?
Yes, the Ruger 9E was designed to accept SR9 magazines, and these 17-rounders are a direct fit. The SR9, SR9C, and 9E all share the same magazine platform for the full-size format, so these mags work interchangeably across all three models.
