Description
This is a genuine Ruger factory magazine built to the same specifications as the magazine that shipped with your SR9C. It holds 10 rounds of 9mm Luger and comes packaged with two different floorplates so you can dial in your grip preference. The flush baseplate keeps things compact when concealed carry matters, while the extended floorplate adds a finger rest for better purchase and control during shooting.
The magazine body is constructed from blued steel with a polymer follower and steel wire spring inside. You get witness holes along the side of the magazine so you can do a quick round count at a glance without dropping it and guessing. The construction is straightforward and proven, with the same attention to fit and tolerance that Ruger applies to all their replacement magazines.
SR9C Magazine Compatibility and PC Carbine Use
This magazine works directly with the Ruger SR9C pistol, and it's also compatible with the Ruger PC Carbine when you have the SR9/S9 magazine well insert installed. If you're running both the compact pistol and the carbine with the matching magazine well, this gives you the ability to share magazines across both platforms. This magazine does not fit the full-size SR9 or the Security-9 pistol.
What to Expect on First Use
Brand new magazines come with a stiff spring, and that's by design. The tension keeps rounds feeding reliably after years of use. Your new magazine will load a bit tighter when you first get it, especially that final round into the chamber. This is completely normal and will ease up as you use it. Loading and unloading the magazine a few times over a week or two speeds up this break-in process. If you're hitting the range right away, the act of cycling rounds through will naturally loosen things up as you go.

Frequently Asked Questions
Why is my new SR9C magazine so stiff to load?
New magazine springs come with extra tension to ensure they maintain reliable feeding pressure throughout their lifespan. This stiffness is normal and will ease up with use. Cycle rounds in and out of the magazine several times over a week or two to speed up the break-in, or simply take the magazine to the range and it will loosen naturally as you shoot.
Can I use this 10-round magazine with the PC Carbine?
Yes, this magazine works with the PC Carbine when you have the SR9/S9 magazine well insert installed. If your carbine has that specific insert, this magazine will feed reliably. Check your magazine well markings to confirm which insert you have, as the PC Carbine can accept different magazine well types for various platforms.
Is there a difference between the flat and extended floorplates?
The flush floorplate keeps a lower profile for concealment, while the extended floorplate adds a finger ledge to give your pinky more purchase and control. Try both and use whichever feels more comfortable for your hand size and shooting style. Swapping them is quick and simple.
Do witness holes help me know how many rounds are loaded?
Yes. The numbered witness holes run along the side of the magazine body, so you can count your rounds at a glance without removing the magazine or manually dropping rounds to count. It's a simple feature that saves time and makes managing your ammunition easier at the range.
