UPC: 706397904319
Made for XD-S .45 ACP with #1 Backstrap & 3.30"–4" Barrel
This is a Springfield Armory OEM part, engineered specifically for:
XD-S pistols chambered in .45 ACP
Pistols using the #1 backstrap (the smaller backstrap option for a shorter reach and slimmer feel)
Models with 3.30" to 4" barrels, typical of carry and defensive configurations
Because it’s built to match the #1 backstrap contour, the XDS5001M:
Sits flush with the backstrap and frame
Aligns cleanly with compatible extended magazines
Maintains the XD-S’s factory profile and lines while adding functional grip length
If you love the slim feel and shorter reach of the #1 backstrap, this sleeve is the correct companion for your extended magazine setup.
One-Piece Polymer Construction – Strong, Simple, and Dependable
The 1-piece polymer design keeps this backstrap sleeve:
Simple to install – just slide it onto the appropriate extended XD-S .45 ACP magazine
Durable under real-world use – made from tough polymer that resists impacts and daily wear
Lightweight – preserving the XD-S’s advantage as a compact, easy-to-carry defensive pistol
No extra screws, plates, or add-ons—just a clean, robust sleeve that integrates your mag and frame into one cohesive gripping surface.
Black Finish – Factory-Matched, Low-Profile Look
The black finish of the XDS5001M:
Matches standard black XD-S frames and controls for a seamless factory appearance
Works well with two-tone or custom finishes, maintaining a low-profile, defensive-ready aesthetic
Keeps your pistol setup subdued and professional, ideal for concealed carry and duty use
If you prefer the classic black-on-black defensive look, this backstrap sleeve keeps everything visually consistent and discreet.
Fills the Grip Gap with Extended Magazines
When you use an extended magazine in your XD-S .45 ACP, there’s often a noticeable gap between the bottom of the grip frame and the top of the magazine base. The XDS5001M is designed to:
Eliminate that gap, creating a continuous gripping surface from backstrap to magazine base
Give your hand a more secure, three-finger purchase—especially important when managing .45 ACP recoil in a compact pistol
Reduce the risk of pinched fingers or uncomfortable grip edges during firing and reloads
Enhance control for faster, more accurate follow-up shots in training or defensive use
A better interface between frame and magazine means your XD-S feels more like a full, cohesive grip and less like a compact compromise.
Ideal for Concealed Carry, Range Practice & Home Defense
This backstrap sleeve is especially useful if you:
Carry your XD-S .45 ACP daily and want a more confident grip with extended magazines
Spend time at the range practicing with the same configuration you carry for real-world consistency
Use your XD-S as a home-defense handgun and prefer the extra control and capacity of extended magazines
By improving grip ergonomics without adding unnecessary bulk, the XDS5001M helps your XD-S perform better in any defensive or training role.
Easy Installation – Drop-On OEM Fit
Using the Springfield XDS5001M is straightforward:
Confirm your XD-S .45 ACP is unloaded and configured with the #1 backstrap.
Slide the black polymer sleeve over the correct extended XD-S .45 ACP magazine.
Seat the sleeve firmly against the magazine baseplate.
Insert the magazine into your XD-S and check that the sleeve:
Fits flush with the frame and backstrap
Does not interfere with mag insertion, lockup, or release
Once installed correctly, the sleeve remains in place on the magazine, giving your pistol a factory-finished, integrated grip profile.
OEM Springfield Quality – Designed for Reliability & Fit
As a genuine Springfield Armory factory accessory, the XDS5001M offers:
Precise fitment tailored to the XD-S .45 ACP platform with #1 backstrap
Consistent polymer quality and color to match other Springfield parts
The peace of mind that comes from using correct, tested, and approved components on a defensive handgun
When it comes to carry pistols, OEM parts are often the best way to maintain reliability, warranty compliance, and consistent performance.
