Built for the XD Compact .45 ACP
This magazine is engineered specifically to fit the Springfield XD Compact .45 ACP double-stack frame. The dimensions, feed geometry, and X-Tension sleeve are all tuned for this model, providing:
A secure, drop-free fit in the XD Compact frame
Reliable feeding and slide lock on empty with quality ammunition
A seamless transition from the pistol grip to the Dark Earth sleeve for a full-hand purchase
Because it’s a Springfield Armory OEM magazine, you get the same engineering, testing, and quality control that goes into the mags shipped with the pistol from the factory.
10-Round Capacity – State-Friendly Firepower
The XD4551 provides a 10-round capacity in .45 ACP, which is ideal if you:
Live in an area with magazine capacity restrictions
Prefer to standardize your XD Compact mags at 10 rounds for training and carry
Want a balance of manageable recoil and control with a slightly lighter mag
Paired with the XD Compact’s shorter slide and grip, this mag gives you a solid, controllable .45 ACP platform that still hits hard while staying within legal limits in many jurisdictions.
(Always verify your local, state, and federal laws regarding magazine capacity before purchase or use.)
Stainless Steel Construction – Durable & Corrosion-Resistant
The tube of the XD4551 is made from stainless steel, which offers several important advantages:
Enhanced durability and structural rigidity to keep feed lips properly aligned
Corrosion resistance against sweat, humidity, and daily carry conditions
Smooth internal surfaces that work with the follower and spring for consistent feeding
Whether you’re running this mag in a nightstand gun, range pistol, or everyday carry setup, stainless construction helps ensure it will stand up to hard use.
Dark Earth Grip X-Tension – Full-Size Feel on a Compact Frame
A standout element of this magazine is its Dark Earth Grip X-Tension sleeve. This extension is designed to mate perfectly with the shorter XD Compact grip, offering:
A full-hand grip with support for your pinky finger
A consistent, comfortable feel that mirrors a full-size XD grip profile
A unique Dark Earth accent that complements FDE and earth-tone gear, holsters, and accessories
Better control under recoil, especially when firing hotter defensive .45 ACP loads
With the XD4551 inserted, many shooters find their XD Compact handles more like a full-size pistol, without giving up the compact slide length and balance they prefer for carry and quick handling.
OEM Reliability – Built by Springfield, for Springfield
Because this is a genuine Springfield Armory magazine, you’re not dealing with guesswork on fit or function:
Correct mag catch cutouts and dimensions for proper lockup
A factory-tuned follower and spring designed for .45 ACP in the XD Compact platform
Reliability tested as part of Springfield’s OEM mag lineup
If you’ve had mixed experiences with off-brand mags, stepping up to XD4551 OEM magazines can be a simple way to improve reliability for both training and defensive use.

Basic Maintenance & Care
To get the most out of your XD4551 10-round XD Compact magazine:
Inspect regularly for dents, cracks, or damage to the tube, base, or X-Tension sleeve.
Disassemble and clean the mag body, follower, and spring periodically—especially after high-round-count sessions or exposure to dirt, sand, or moisture.
Avoid over-lubrication inside the mag; excessive oil can attract debris and affect feeding.
Rotate between carry and range mags to even out wear and quickly identify any magazine that starts to exhibit issues.
With simple care, this OEM magazine will deliver long service life and steady performance.
