Extended Capacity with a Better Grip
This 7-round magazine is designed to:
Add one extra round beyond typical flush-fit capacity (depending on your original mag), giving you more firepower in a compact platform.
Provide a longer gripping surface thanks to the integrated FDE extension, so your pinky has a secure place to rest.
Improve overall recoil control and comfort, especially helpful with the snappier .40 S&W in a slim single-stack frame.
For many shooters, this mag becomes the go-to option for carry, home defense, and serious range training because it simply makes the XD-S easier and more comfortable to shoot.
Stainless Steel Construction – Strong & Corrosion-Resistant
The stainless steel tube offers:
Excellent strength and durability, keeping feed lips and geometry true over time.
Corrosion resistance, ideal for daily concealed carry where sweat and humidity can be a factor.
Smooth internal surfaces for reliable feeding and consistent slide lock when paired with quality ammo and a well-maintained pistol.
Whether you carry every day or just occasionally, a stainless factory magazine is a smart, long-lasting choice.
FDE Grip Extension – Control, Comfort, and Style
The Flat Dark Earth extension sleeve is more than just good-looking:
It extends the XD-S .40 grip to give you a full three-finger purchase, which helps manage recoil and muzzle flip.
Fills the gap between the mag base and the bottom of the grip, creating a smooth, continuous grip profile with no sharp steps.
Color-matched FDE finish looks great with FDE frames and accessories, or creates a functional two-tone look on black-framed pistols.
If you have larger hands or simply want more control on each shot, this extension makes a noticeable difference.
OEM Springfield Magazine – Built for Reliability
Because this is a Springfield Armory factory magazine, you get:
Correct dimensions and mag catch cuts for proper lock-up and drop-free operation.
A spring and follower tuned specifically for .40 S&W in the XD-S platform.
The reliability you expect when your magazine is part of a defensive carry setup.
For concealed carry, practice, or home defense, OEM magazines remain the most dependable option.
Ideal Uses for the XD-S 7rd .40 SS/FDE Magazine
This XDS4007DE magazine is ideal for:
Concealed Carry: A great balance between capacity, control, and concealability.
Home Defense: Extra round + better grip = more confidence under pressure.
Range Training: More comfortable shooting and fewer reloads per string.
Backup/Spare Mag: Carry as a reload with a flush mag in the gun, or run this as your primary mag for the improved ergonomics.
If your XD-S .40 is your primary self-defense pistol, this mag is a smart upgrade.
Maintenance & Care Tips
To keep your Springfield XD-S .40 7-round SS/FDE magazine in top shape:
Inspect regularly for dents, bent feed lips, or damage to the extension.
Periodically disassemble and clean the tube, spring, and follower—especially after exposure to dirt, sand, or pocket lint.
Avoid heavy oil inside the mag; a dry or lightly lubricated interior works best to prevent debris build-up.
Rotate between carry and training mags to even out wear and quickly spot any problem magazines.
Proper maintenance helps ensure your magazine stays reliable when it matters most.
