Description
Springfield's XD Mod.2 Sub-Compact in .45 ACP ships with two different magazines for a reason: one keeps the grip trim for concealment, and the other, this one, adds rounds and a more secure hold. The XDG4551FDE is the 10-round extended magazine with Springfield's FDE X-Tension grip sleeve, and it's a direct factory replacement built to the same specs as what came in the box with your pistol.
The magazine body is stainless steel, which holds up well over time and resists corrosion from sweat and holster wear. Inside, a steel spring pairs with a polymer follower to keep cartridges properly aligned and feeding cleanly. The fit is tight and wobble-free, which matters when you're running drills or relying on the gun for defense. The impact-resistant polymer baseplate also provides a bit of protection if you're doing hard mag changes at the range.
The FDE X-Tension sleeve does double duty here. It gives the magazine a grip length that fills out your hand better than the shorter flush-fit option, and it ties in visually with FDE-finished XD Mod.2 pistols for a clean, coordinated look. The textured surface on the sleeve adds grip right where your pinky and palm need it most, which makes a noticeable difference on a sub-compact .45.
This is a purpose-built magazine for the XD Mod.2 Sub-Compact specifically. If you have the standard XD Sub-Compact or an XD-M, double-check compatibility before ordering. Springfield backs this magazine with a lifetime warranty, so you're covered if anything goes sideways. Worth picking up a couple if you shoot this platform regularly.

Frequently Asked Questions
Will the XDG4551FDE fit my XD Mod.2 Sub-Compact .45 ACP?
Yes, this magazine is specifically designed for the Springfield Armory XD Mod.2 Sub-Compact chambered in .45 ACP. It is not cross-compatible with the standard XD Sub-Compact, XD-M, or other calibers. If you're unsure which variant you have, check the model designation on your pistol's frame or the original paperwork.
What is the X-Tension sleeve and does it affect how the gun carries?
The X-Tension sleeve is a textured polymer grip extension that wraps around the base of the magazine, effectively lengthening the grip of the XD Mod.2 Sub-Compact when this mag is inserted. It gives you more hand contact on the gun and adds a round of capacity compared to the flush-fit 9-round option. When carrying concealed with this magazine, the extended grip will print slightly more than the shorter mag, so most people use the flush-fit for carry and keep this one as a spare or for range use.
Is this a genuine Springfield Armory magazine or an aftermarket product?
This is a genuine OEM factory magazine made by Springfield Armory to the same specifications as the magazines that ship with new pistols. It comes with a lifetime warranty from the manufacturer. Sticking with factory magazines is the safest bet for reliable feeding and guaranteed fit.
How does the 10-round magazine compare to the other XD Mod.2 .45 ACP magazine options?
Springfield offers the XD Mod.2 Sub-Compact in .45 ACP with a 9-round flush-fit compact magazine and a 13-round extended magazine, in addition to this 10-round option. The 10-rounder with FDE sleeve lands in the middle, offering more capacity than the flush mag while being slightly less bulky than the full 13-round version. It's a practical balance for those who want a little extra without going to the maximum capacity option.
Does the FDE color on the sleeve match Springfield's FDE pistol finish?
Springfield designed the FDE X-Tension sleeve to coordinate with their FDE-finished XD Mod.2 pistols, so the color match is consistent across the product line. That said, FDE shades can vary slightly between manufacturers and production runs, so if color matching matters to you, it's worth comparing in person when possible.
