One-Piece Polymer Construction – Simple & Tough
The 1-piece polymer design of the XDS5901M keeps things simple and durable:

Impact-resistant polymer stands up to daily carry, range sessions, and repeated mag changes
Lightweight design maintains the XD-S’s reputation as a compact, easy-to-carry platform
Install it once, pair it with the right extended magazine, and enjoy a clean, dependable grip enhancement with no extra fuss.
Black Finish – Clean, Factory-Matched Look
Finished in black, this backstrap sleeve:
Blends perfectly with black XD-S frames, baseplates, and controls, keeping a factory-correct look
Works equally well with contrasting or two-tone setups if you prefer a clean, understated finish
Maintains a low-profile appearance that doesn’t attract unnecessary attention—ideal for concealed carry
If you want your extended magazines to look like they truly belong on your XD-S, this black OEM sleeve completes the package.
Smoother, Fuller Grip with Extended Magazines
When used with compatible extended magazines, the XDS5901M sleeve offers a noticeable improvement in how your XD-S feels and handles:
Fills the unsightly and uncomfortable gap between the bottom of the frame and the top of the magazine base
Creates a continuous gripping surface, which:
Helps eliminate pinch points
Gives your pinky finger a more secure purchase
Improves overall control during recoil
Allows for better recoil management and tracking of sights, especially in fast strings or defensive drills
For many shooters, this kind of grip enhancement makes the difference between a pistol that’s merely carryable and one that’s truly enjoyable and confidence-inspiring to shoot.
Ideal for Concealed Carry, Training & Home Defense
The Springfield XD-S 9mm is built to be carried—and this sleeve is built to optimize carry-focused configurations:
Concealed Carry:
Extended magazines often ride in the gun or as a spare; this sleeve ensures they feel as good as they function.
Range Practice & Drills:
Running the same extended mag setup on the range that you carry on the street helps reinforce consistent grip and control.
Home Defense:
A fuller grip with an extended magazine provides more control in high-stress, low-light scenarios.
If the XD-S is part of your defensive lineup, this backstrap sleeve helps you get the most out of your extended mags.
Easy Installation & Use
Installing and using the XDS5901M is quick and straightforward:
Ensure the firearm and magazine are unloaded and safe to handle.
Slide the black polymer sleeve onto the compatible extended XD-S 9mm magazine.
Seat the sleeve against the magazine baseplate as designed.
Insert the magazine into your XD-S 9mm with #1 backstrap and 3.30"–4" barrel.
Confirm the sleeve sits flush with the grip frame, with no interference in seating or releasing the magazine.
Once installed properly, the sleeve stays in place and gives your extended mag a factory-fitted, integrated appearance and feel.

Factory-level reliability and fit for the XD-S platform
Matching aesthetics with Springfield’s standard black parts and finishes
Confidence that the part is designed to function in harmony with your firearm, not against it
