Built for XD-S 9mm with #1 Backstrap & 3.30" Barrel
This is not a universal sleeve—it's a Springfield OEM component precisely molded for:
XD-S 9mm pistols
Using the #1 backstrap (the smaller backstrap option)
3.30" barrel variants, commonly carried for concealed self-defense
That means:
The curves, angles, and dimensions are matched specifically to the #1 backstrap profile, ensuring a tight, factory-correct fit.
When paired with an appropriate extended magazine, the sleeve fills the empty space and completes the grip for a more natural, full-hand hold.
If you’re running the #1 backstrap and want the best possible fit and feel with your FDE setup, this is the exact sleeve you’re looking for.
One-Piece Polymer Design – Strong, Simple, Reliable
The 1-piece design of the XDS5901MFDE sleeve offers several functional advantages:
No screws or moving parts to work loose or go missing.
High-strength polymer construction that resists impact, flex, and everyday wear.
Simple installation—slide the sleeve onto the proper extended magazine and seat it into the pistol.
This keeps your XD-S carry setup lightweight, snag-free, and dependable, even with frequent practice and carry.
Flat Dark Earth Finish – FDE Grip Sleeve to Match Your XD-S
The Flat Dark Earth (FDE) finish gives your XD-S a modern, tactical look:
Complements FDE frames, magazines, and accessories for a cohesive build.
Works as a subtle contrast on black-framed XD-S 9mm pistols, if you prefer a two-tone aesthetic.
Keeps your pistol’s appearance professional and low-glare, ideal for defensive carry.
If you’re building an FDE-themed XD-S or just want your extended magazine grip extension to match your pistol, this OEM sleeve is the perfect finishing touch.
Improved Grip, Control & Comfort with Extended Magazines
When used with the correct extended magazine, the Springfield XD-S backstrap sleeve:
Eliminates the gap between the bottom of the XD-S grip and the extended magazine base, preventing the feeling of a “step” or exposed magazine body.
Provides a smoother, more complete gripping surface, especially beneficial for larger hands.
Helps you achieve a solid, three-finger purchase on the gun, improving recoil management and stability.
The result is a more confident, controllable shooting experience, especially during:
Factory Fitment & OEM Quality
As a genuine Springfield Armory factory part, the XDS5901MFDE offers:
Perfect dimensional compatibility with the XD-S 9mm (#1 backstrap, 3.30" barrel).
Consistent color and texture quality associated with Springfield OEM accessories.
Peace of mind knowing you’re using a product engineered specifically for your firearm, not a generic aftermarket workaround.
For many concealed carriers, staying with OEM parts is the easiest way to maintain reliability, aesthetics, and long-term value.
Ideal for Concealed Carry, Range Training & Home Defense
This XD-S FDE backstrap sleeve is especially useful if you:
Carry your XD-S 9mm daily and prefer an extended magazine for more capacity and better grip control.
Spend time at the range practicing with the same configuration you carry, and want a more comfortable, secure grip.
Use your XD-S as a home-defense pistol and want maximum control under stress.
By smoothing out the grip interface with your extended mag, you get a pistol that’s easier to hold onto when it matters most.
Easy Installation
Using the XDS5901MFDE is straightforward:
Ensure your pistol and magazines are unloaded and safe.
Slide the FDE backstrap sleeve over the correct extended magazine until it seats against the baseplate.
Insert the magazine into your XD-S 9mm with #1 backstrap and 3.30" barrel.
Verify that the sleeve sits flush against the grip and does not interfere with magazine seating or function.
Once fitted, the sleeve stays in place and gives your extended magazine a factory-quality integrated look and feel.
