If you’re looking to improve control, fill the gap between the frame and magazine, and add a custom FDE accent to your XD-S, the XDS5001MFDE is the factory-style solution made just for your setup.
Designed for XD-S .45 ACP with #1 Backstrap & 3.30" Barrel
This sleeve is not universal—it’s tailored for a very specific configuration so the fit and contour are just right:
Because it’s matched to Backstrap #1, the sleeve’s shape follows the grip profile you’ve already chosen, preserving your preferred trigger reach and feel while extending the grip to meet your magazine base.
Fills the Gap Between Grip Frame and Magazine
From the factory, extended magazines on the XD-S often leave a small but noticeable gap between the bottom of the grip frame and the mag base. The XDS5001MFDE is engineered to slide down over the top of the magazine and lock up against the frame, filling that gap for a seamless grip.

Benefits of filling the gap:
More secure firing grip—no more pinky hanging in space
Improved recoil management, especially with snappy .45 ACP loads
Better comfort during longer range sessions and training days
A clean, integrated look that makes the mag and frame feel like one continuous unit
The design doesn’t add capacity (this is a 0-capacity magazine sleeve), but it dramatically enhances how the pistol sits in the hand. Pelcher Outdoors+2Ready Gunner+2
Flat Dark Earth Finish – Function Meets Style
The Flat Dark Earth (FDE) finish gives this sleeve a modern, tactical look that pairs perfectly with FDE frames, magazines, and holsters—or provides a sharp two-tone accent on a black XD-S. Abide Armory+3Ready Gunner+3Big Country Sporting Goods+3
Why shooters love FDE on the XD-S:
Visual contrast improves quick visual confirmation of magazine seating
Matches many FDE holsters, mag carriers, and accessories
Adds a custom, upgraded look without altering the pistol’s function
If you’re building an FDE-themed carry setup, the XDS5001MFDE is a natural addition.
1-Piece Polymer Design – Strong, Lightweight, and Simple
Built from tough polymer in a 1-piece design, the XDS5001MFDE is engineered to be both rugged and lightweight: Abide Armory+4Desperate Measures Firearms+4Ready Gunner+4
Durable: Polymer construction resists impacts, drops, and everyday carry abuse.
Lightweight: Weighs only a fraction of an ounce (around 0.08 oz), so it doesn’t upset the balance of your XD-S. Ready Gunner
Weather-resistant: Polymer won’t rust or corrode from sweat, humidity, or rain.
No moving parts: The one-piece design keeps things simple and reliable.
It’s a true “install it and forget it” accessory that holds up to regular concealment, training, and carry.
Easy Installation – Slides Over the Magazine
Installing the Springfield XDS5001MFDE Backstrap Sleeve is straightforward and does not require gunsmithing:
Unload your firearm and remove the magazine.
Slide the sleeve down over the top of your XD-S magazine.
Push it until it rests firmly on the magazine base.
Insert the magazine into your XD-S and confirm the sleeve meets the grip frame with no gap.
Once installed, the sleeve stays on the magazine, so every time you lock that mag into place you automatically get a fuller, more comfortable grip. Big Country Sporting Goods+3Pelcher Outdoors+3Desperate Measures Firearms+3
Enhances Control for Concealed Carry & Range Use
For a slim single-stack .45, the XD-S is known for its concealability—but that compact size can make grip and recoil management more challenging, especially for shooters with larger hands. This mid-sized sleeve helps bridge that gap:
More grip surface = better control during rapid strings and defensive drills
Less felt flip as your support hand has more real estate to hold onto
Increased confidence when shooting full-power .45 ACP in a small package
Whether you’re carrying every day or just running your XD-S at the range, the improved ergonomics can translate into faster follow-up shots and tighter groups. Abide Armory+3Ready Gunner+3Big Country Sporting Goods+3
Compact Upgrade That Maintains Concealability
Even though the sleeve extends the gripping surface to meet the magazine base, it’s still designed around the compact footprint of the XD-S 3.3". You get:
A more “full-size” feel in the hand when the extended mag is inserted
Minimal change to your holster fit and concealment profile
A factory-style contour that doesn’t snag like improvised grip extensions sometimes do
For many carriers, this sleeve is the sweet spot between shootability and concealment—you get the control of a longer grip when you want it, without moving to a larger firearm.
