Description
If you're running a Hellcat and want more capacity without a bulky mag, this 15-rounder delivers where it counts. It holds a full 15 rounds of 9mm while measuring just 0.28 inches taller than the standard 13-round extended magazine, so you're gaining meaningful firepower with minimal impact on your carry setup.
What Makes the Hellcat 15-Round Magazine Stand Out
The real strength here is the balance Springfield struck between capacity and size. The stainless steel construction means you get durability that won't fail you, while the black polymer follower ensures smooth, reliable feeding shot after shot. The numbered witness holes let you glance down and know exactly how many rounds you've got left, which is useful whether you're training or depending on the gun. The FDE extension isn't just for looks either, it matches the Hellcat's Adaptive Grip Texture pattern, giving you better purchase on the gun during reloads and extended shooting sessions.
Compact Enough for Carry, Capable Enough for Training
This magazine works well for both roles. At the range, the extra two rounds mean you're reloading less and shooting more, which is where real learning happens. For carry purposes, the FDE color meshes with most Hellcat configurations, and the grip extension gives you better hand positioning if you've got larger fingers or want more control. The magazine locks into the frame with virtually no gap, so there's nothing snagging on your clothing or catching on gear.
Built to Last and Perform
Springfield's factory magazines are known for just working, and this one is no exception. The stainless steel body resists corrosion, the spring design is proven across the entire Hellcat line, and the whole assembly drops free from the pistol without binding. It's the kind of magazine you buy once and stop thinking about.

Frequently Asked Questions
Will the Hellcat 15-round magazine fit both the original Hellcat and Hellcat Pro?
The FDE extended magazine is designed for the standard Hellcat. The Hellcat Pro has different dimensions and requires its own 15-round flush-fit magazine. Check your pistol's specs before ordering to make sure this magazine is the right fit.
How much harder is it to load this magazine compared to the 13-round version?
You will need more hand strength to push rounds down when the magazine gets full, since you're compressing the spring tighter. Many users find that a mag loader makes filling it to capacity much easier, and Springfield includes one with their Hellcat pistols. Once you load it a few times, most people get the technique down.
What's the advantage of getting this 15-round magazine instead of just carrying a second 13-round mag?
With only 0.28 inches of additional length, you get two extra rounds without a noticeably bulkier carry setup. For training and range time, it means fewer reloads. If you're using it as a backup magazine while carrying, the minimal size difference makes it practical to actually carry and deploy without breaking your grip or printing heavily.
Are the witness holes reliable for checking how many rounds remain?
Yes, the numbered witness holes are a straightforward way to count your remaining rounds at a glance. They're visible from the side of the magazine and line up with each round in the magazine. This feature is especially useful when you're training or running drills where knowing your ammunition status matters.
