Description
This magazine is the missing piece if you're running an Advantage Arms .22 LR conversion kit on your Springfield XD. It's built specifically for that job, which means it'll work the way you expect without any guessing games about compatibility.
What the Magazine Does
You get a 10-round polymer magazine that feeds .22 Long Rifle ammo cleanly through your conversion kit. The polymer construction keeps it light and durable, and there's a steel spring inside that's rated to handle extended use. One detail that matters if you pay attention to these things: it has a last-round hold open feature, so the slide locks back when you empty the mag. Not all rimfire conversions nail this, but Advantage Arms did here.
Compatibility Notes
Make sure you've got a standard XD frame. This magazine will not work with XDM frames. It also won't do anything by itself. You need the actual Advantage Arms conversion slide kit to make this work. If you're shopping for the whole setup, some retailers bundle them together, which takes the guesswork out of the process.
Real-World Performance
People who run these conversion setups often buy a few extra magazines because you'll want them on hand. The setup runs best when kept clean and well lubricated. Ammo choice matters a bit with rimfire conversions, and using quality .22 LR rounds gives you better results than the cheapest bulk stuff. If you're treating this as a low-cost training tool, that's exactly what this magazine supports.

Frequently Asked Questions
Will this magazine work with my XDM?
No. This magazine is designed specifically for standard XD frames only, not XDM models. Advantage Arms makes a separate XDM magazine if you've got the Mod 2 or later XDM variant.
What do I need to use this magazine?
You'll need the Advantage Arms conversion slide kit for your specific XD model. The magazine by itself won't convert your gun. The conversion kit includes the .22 LR barrel, slide assembly, and other components that make the whole thing work.
Does the last-round hold open always work reliably?
Advantage Arms designed this feature into the magazine, but they note on their site that due to XD spring design variations, the hold open isn't guaranteed to function consistently on every gun. It typically works well, but results can vary by individual frame.
What kind of .22 ammo should I use?
High-velocity, quality-brand ammunition like CCI, Federal, or Remington tends to work best. The conversion kits can be picky about cheaper bulk ammo, and keeping everything clean and well lubricated helps reliability across the board.
